Indian Womens Showing Breasts
Remember the time ....? NO!!
But you've seen recently Claudia Koll?
I mean, I was doing yesterday and zapping me in the beak on Rai Uno Domenica In
And this alone should make you stop reading.
However, if the chick in question and where the singing sounded like the new Santa Maria Goretti, among other TV series in which he also starred as Countess Mazzoleni.
I remembered in "Cosi fan tutte" when it was the bidet, large short robe.
to think of it seems to me that the generation of actresses 80/90 after erotic films should canonized by force (even before its death) on TV.
New starlets do not need this step, after taking it in the mouth become minister or make a career in ShowBizz.
Or both things.

Biological Process Affected Temperature
astronomy
The position of the stars (1) The celestial sphere and its terms of reference universal
E ' the surface on which the stars are projected, and serves to represent and study the layout of the various celestial bodies that surround the Earth. Appears to rotate from east to Oves, the Earth is actually rotating in the opposite direction around an ideal axis of the earth whose extension in space touches the side of the North Pole, the celestial sphere at a point near the star Polaris.
To locate the position of a celestial body, you need some reference points that are universal ie independent of the position of observer:
- the 'axis of the world: it is the ideal line is obtained by extending indefinitely the axis of rotation Earth intersects the celestial sphere in two points called the north celestial pole and south celestial pole.
- The celestial equator: it is obtained by extending the floor space of the Earth, that is, that is perpendicular to the axis of the world passing through the center of the celestial sphere. Parallel circles are parallel to the equator in the sky and the celestial meridians are half circles that combine The celestial poles. If the parallel key is the celestial equator, the celestial meridian passes through what is fundamental point range, the point on the celestial sphere where the Sun is the day of the vernal equinox. The point diametrically opposite is the omega point. The omega point range and are on the celestial equator.
(2) Elements of benchmarks on the celestial sphere
are points whose location depends on the position of the observer.
- Zenit is the point where the vertical raised above the head of an observer
meets the sky - the nadir, the point opposite the zenith
- the celestial horizon is the circumference maximum that divides the celestial sphere in an upper and a lower hemisphere. It is obtained by cutting the celestial sphere with a plane perpendicular to the vertical line to the observer.
- The celestial meridian of the place of observation is the maximum circumference that contains the celestial north and south poles, Zenith and Nadir.
(3) Reference elements of the celestial sphere for an observer at the North Pole and the cardinal points
In this case the vertical axis coincides with the Earth and then Zenit coincides with the north celestial pole, the celestial horizon instead coincides with the celestial equator is the great circle described by the apparent motion of stars in their rotation around the axis of the celestial sphere. The stars are not on this vicious circles and instead, called celestial parallels with a diameter gradually decreasing as one approaches the north celestial pole. Polaris will be at Zenit
East (east or east) and West (west or west) are placed in the intersection points between the celestial equator celestial horizon, where the two planes do not coincide (ie if an observer is not place the pole). The local meridian cuts the horizon at two points which are the North and the South posed by part of the pole of the same name. East, West, North and South are the cardinal points.
(4) Determining the position of the stars: the sky coordinates
To place the stars, the Earth is imagined as a reference point and used the celestial equator and the celestial meridian passing through a particular point, the point range of the Constellation of Aries. The point range is the point where the Sun is the spring equinox, March 21. The absolute coordinates, that is independent from the observer's position are:
- the celestial declination: The angular distance between the star and considered the plan of the celestial equator
- right ascension: the angular distance of the star from the meridian Heavenly passing through the point range
altazimuth coordinates are dependent from the point of observation and are
- Height: measured in degrees from 0 to +90 starting from the horizon to the zenith and visible from 0 to -90 at Nadir
- azimuth: measured in degrees along the 'horizon from the south ie from the point where the meridian intersects the local horizon easure growing west. The compass points south, west, north and east that have respectively azimuth 0 °, 90 °, 180 ° and 270 °.
(5) The unit of distance
astronomical units away are mainly three:
- the Astronomical Unit (AU) is the average Earth-Sun distance and amounts to about 149 000 km 600 . It is used within the limits of the solar system
- Year-light (to) is the distance traveled by light in a year that propagates at a speed of approximately 300 000 km / s. In km corresponds to about 9.463 trillion kilometers
- the Parsec (parallax-second, pc): the distance of a point from which an observer would see the semi-major axis of Earth's orbit, perpendicular from the angle of 1 ". This distance is equivalent to 206,265 times the Earth-Sun distance and amounts to 30 900 billion km or 3.26 years-light. The parsec is a measure derived from the method used to determine the distance of stars, which is based on measuring the angle of parallax. The parallax in astronomy is the apparent displacement of a star against a backdrop of distant stars when observed from two points separated by some distance. The parallax is greater the greater the distance between the two different viewpoints, and this is taken as the basic astronomy in the major axis of Earth's orbit, performing two subsequent observations six months apart from each 'other. The characteristics of the stars
(6) apparent magnitude and absolute magnitude
classes magnitude classify stars according to their apparent brightness or absolute. In the first case the brightness of a star is measured with a photoelectric photometer mounted on the telescope. Were, by the ancient Greek Hipparchus, identified six classes of magnitude, we have seen with photometric between a class and the other there is a difference in brightness of about 2.5 times. The classes of magnitude are more than six hours, arriving even negative magnitudes as in the case of the star Sirius (-1.47). You get to perceive images of stars of magnitude 30.
The stellar luminosity that reaches the Earth depends on the actual light emitted by the distance that separates the star from Earth, the classes are for the magnitude of the apparent magnitude (m), the intrinsic brightness of a star is rather indicated by the absolute magnitude (M) that corresponds to the brightness of individual stars that would show if they were placed at a standard distance of 10 parsecs from us. It can be traced back to the absolute magnitude apparent only if you know the distance to the star, however, measured only for a limited number of stars. It may, however, to extrapolate values \u200b\u200bof absolute brightness from the study of stellar spectra.
7) Discuss the information that can be drawn from the study of double stars
The double stars are very close pairs of stars that revolve around their gravitational center of gravity. The study of their orbits (and thanks to the law of universal gravitation) can be traced to their mass, physical parameter otherwise very difficult to determine. These studies showed that most stars have examined mass of between 1 / 10 and 50 times that of the Sun. It 'also possible to derive the diameter of the stars based on the period of concealment of an observer on Earth. Walking around the center of gravity in fact, passing the one before the other, are hidden to each other for a period dependent on their size. They then discovered exceptionally small stars such as neutron stars, as well as the exceptionally large supergiant star with a diameter of more than a thousand times that of the Sun.
8) Describe a stellar spectrum, explaining how you get
Most of the spectra collected from celestial objects is represented by absorption spectra and only in certain situations you have emission spectra. The absorption spectra are obtained when the continuous radiation, coming from the star passes through a low-pressure gaseous substance and less of the hot source, consisting of stellar atmosphere. In this case, the atmospheric gas absorbs some of the radiation emitted by the source, if the radiation is then refracted (prism), we get a colorful spectrum (as a continuous spectrum) interrupted by dark lines or bands corresponding to the absorbed radiation. The number and placement of absorption lines on the spectrum reflect the chemistry of the stellar nature was analyzed to be remarkably uniform in the stars: hydrogen and helium about 80% to 19%, the remainder may comprise all other chemical elements we know.
9) Say how you look at a stellar spectrum in the information that if they draw
The spectrum of the stars is obtained by passing their light through a prism attached to a telescope. It seems a stretch all the colors of the rainbow, from red to blue, interrupted by black lines corresponding to wavelengths missing. The intensity of colors provides background information about the star's surface temperature while the position Black lines informs us about the chemical composition of stars (the outside of the stellar gas). The stars were classified into spectral classes, named by the letters O, B, A, F, G, K, M, reflecting decreasing temperatures. The Sun belongs to the class G that includes yellow stars and surface temperatures of 5000-6000 K. The data instead indicate a prevalence of the chemical composition of hydrogen, about 80%, and approximately 19% helium. The remaining 1% contains all other elements of the periodic table, but not present in all stars.
10) Explain how the Doppler effect applied in the light gives information about the motion of removal approach with respect to Earth or a celestial body
The Doppler effect is a phenomenon that affects all sources of waves, especially for the light that happens when a star is approaching or moving away from an observer on Earth, its spectrum appears with lines respectively move toward the blue (blue shift) or towards the red (red shift). The effect is that in an apparent change in frequency or wavelength of the radiation received. Christian Doppler in 1845, this phenomenon occurred, with the sound waves, firm stance on a railroad track, putting to hear the sound emitted by a car full of musicians: const that the pitch increased when the car was approaching, was decreased when moving away. For the starlight effect of stretching or contraction of wavelengths becomes visible due to the slippage of the spectral lines.
11) What is the space between the stars? There
interstellar matter: very fine dust and gas. This material is not dispersed homogeneously in space but is often found in clusters with dense fog-like appearance and therefore called nebulae. They may or darker than a fund of stars (dark nebulae), or low light because they reflect light and very bright stars very close (nebulae reflection). Only a few can emit a faint light of their own (emission nebulae) the result of a phenomenon of fluorescence produced by the interaction of ultraviolet rays of a few stars near the gas cloud.
The interstellar matter, where it thickens, it can produce new stars.
The evolution of celestial bodies
12) Construction of the HR diagram
E 'was created, independently of each other, the two scientists Hertzprung E. and HN Russell between 1911 and 1913. This is a two-dimensional diagram which highlights the relationship between temperature (abscissa) and absolute luminosity (ordinate) of the stars. Having
data on the visible stars can be seen that their position on the diagram is not random nor are they present in a diffuse way, but instead deal with particular areas. Most are located in a diagonal band, called the main sequence of stars made in which size and temperature are decreasing from top to bottom. The Sun occupies the central region of the sequence. Almost all the remaining stars are arranged in two quite separate areas of the diagram: at the top and right of the sequence is the area of \u200b\u200bvery bright but relatively cool stars (giants and red supergiants), lower left we find very small stars hot (white dwarfs). About 85% of stars belong to the sequence main, only 3-6% to 10% of white dwarfs and the giants and red supergiants.
13) Relation between mass and luminosity of stars
HR diagram relates the brightness temperature without specifying the relationship of these two parameters with the mass of the stars. However, it was later seen that in the brightness of a main sequence star is proportional to its mass: the white-blue stars of the sequence are also those with greater mass, while the red stars, cooler and less bright, are those that have lowest mass. The mass-luminosity relation is not valid for the stars but who are away from the main sequence. For example, White dwarfs are small (small diameter) but have very high mass and therefore a high density. In contrast, the red supergiant star at the top right are bright because they have very large surface, but their mass is relatively small as well so their density.
14) Interpretation of the HR diagram
The HR diagram is a point of reference for understanding all the phenomena of color changes, size and temperature that the stars undergo during their existence, namely to study stellar evolution . The current interpretation of the record is based on the assumption that every region of the diagram is occupied in a stadium can the life of a star, then the denser regions of stars (main sequence) are the evolutionary phase in which a star spends most of its existence. The photographer then the HR diagram stars in different evolutionary stage, captured at the same time. His study led to the conclusion that the position of a star in the diagram is not fixed but depends on factors such as mass, age, chemical composition, which change over time.
In the main sequence, where is the maximum density of points, is the longest and most stable phase in the life of a star. White dwarfs and red giants are different stages of evolution from main sequence stars.

The Julian calendar and the Gregorian
The custom of celebrating the New Year's Eve is old but not ancient.
The ancient Romans used for many centuries a calendar lunar: Romulus, first king of Rome, had divided the year into 10 months and the year began in March, with the spring.
Julius Caesar decided to instead go to the solar calendar, which lasts 365 days a year, every four years is a leap year and 12 months. A nearly equal to that of today, but not totally identical. The beginning of the new year was still very elastic, celebrated between January and March depending on the location. The Julian calendar
considered the average duration of a year of 365 days and 6 hours (every 4 years and this is retrieved 24 hours a leap year). In fact Julius Caesar's astronomers had miscalculated by 11 minutes and 14 seconds.
little thing, you think! But the great thing, because it accumulates so every 128 years a day late: in 1582 days of delays were even 10!
This complicated life even to the Vatican that began to have problems to fix the date of Easter. In fact, Pope Gregory XIII
must have thought: "If we go on like this sooner or later the Easter we celebrate at Christmas! No no, here we must find a remedy."
So, in October of 1582 the calendar is reformed. First we recover the lost ten days (October 4, 1582 and we went directly to 15 October). At the same time, not to create too much
The planet Saturn in the Chronograph of 354
confusion, since October 4 was a Thursday, the day after, October 15, automatically became a Friday.
Then he lay down new rules for leap years, so that in the long term should not happen again what happened with the Julian calendar.
New Year, even after the spread of the Gregorian calendar, we continue to celebrate on different days depending on geographical areas. In many cities, the beginning of the year in March (Florence and Pisa 25, Venice 1), anyone celebrating Christmas, in southern Italy is celebrated according to the Byzantine tradition on 1 September.
At the end of the seventeenth century Pope Innocent XII indicates January 1 as the first day of the year. And slowly over most of the world accepts this date.
remain naturally different traditions: the Orthodox Church follows the Julian calendar and the Muslim world that follows a lunar calendar when the year is 11 days shorter than solar (in 2008 the Islamists have in fact celebrated twice New Year, once in January for the arrival of 1429 and once in December for the arrival of 1430), the Iranian New Year, the Norouz, is celebrated with the spring equinox, March 21, and then in the various traditions Eastern New Year falls on different days.
One last thing. The fascist regime attempted to revolutionize the calendar by setting the date of 28 October (anniversary of the March on Rome) as a new year of the Fascist Era. Fortunately the attempt was a fiasco.
And luckily none of today's politicians are still coming in such an idea. Ma .. never say never.

Vitamin D
See also Vitamin D: Vitamin D in foods, vitamin A deficiency D
Vitamin D is needed for bone formation:
deposition of calcium and phosphate in the regions of cartilage;
absorption of calcium (and its phosphate) in the digestive tract;
mobilization of calcium from bone;
renal reabsorption.
CHEMICAL STRUCTURE
The term vitamin D is defined as all compounds with biological activity and are characterized by being calciferol derivatives ciclopentanoperidrofenantrene. The
calciferol (vitamin D3) is the form naturally in mammals, while the ergocalciferol (vitamin D2) is formed upon exposure to ultraviolet light ergosterol (Provitamin form of plant origin). The
calciferol is 50-100 times more active dell'ergocalciferolo (D3 is more active than D2).
Both ergocalciferol that calciferol are inactive forms of vitamin D is therefore needed an activity that occurs in the liver and kidneys.
Man is able to synthesize cholecalciferol from a precursor, which function as provitamin: The dehydrocholesterol (derived from cholesterol reduction). This pro-vitamin is found in skin, so to absorb solar radiant energy that causes the isomerization to cholecalciferol (see synthesis of cutaneous vitamin D). Adequate exposure to sunlight thus reduces the need for vitamin D.
ABSORPTION
The calciferol is absorbed in the intestine of lipids in the same way: enter then become part of the micelles (formed by combination of bile salts with the products resulting from hydrolysis of lipids), is absorbed by diffusion passive in the enterocytes and subsequently incorporated into chylomicrons and transported into the circulation through the mesenteric lymphatic vessels.
Unlike the other fat-soluble vitamins are not stored in the liver calciferol. The amount of calciferol from the diet, however, is very low and the majority of vitamin D is synthesized in the skin by the action of ultraviolet light.
Functions of vitamin D
Vitamin D is essential for the maintenance of calcium and phosphate. The metabolically active form is the 1, 25 - (OH) 2-cholecalciferol which acts by promoting:
calcium absorption in the intestine;
the absorption of calcium and phosphorus in the proximal convoluted tubule;
the deposition of calcium level of bone. The
calciferol acts with a mechanism of action of hormone-because:
is synthesized by the human individual;
acts on a target organ;
has a structure reminiscent of steroid hormones. VITAMIN
DE FOOTBALL
The 1, 25 - (OH) 2-cholecalciferol stimulates the synthesis of CaBP (calcium-carrying protein) in the target organ (enterocytes), intervening at the level of intestinal transcription of DNA encoding the protein and RNA polymerase plasma.
Use dell'actinomicina D and a-amanitin inhibitors of transcription and RNA polymerase, respectively, confirm this action.
This new RNA is synthesized which promotes the synthesis of CaBP necessary to facilitate the absorption of calcium.
It is now certain that this process is involved in the cyclic AMP, which increases in the tissues by the action of vitamin D active.
deficiency and toxicity of vitamin D
The early signs of lack of calciferol are:
reduction of serum calcium and phosphorus
secondary hyperparathyroidism and increased alkaline phosphatase in serum.
signs later are:
inadequate skeletal mineralization (rickets in children, osteomalacia in adults);
muscle weakness, abdominal pain
.
Rickets appears in children between 4 and 24 months of age and is basically inadequate bone mineralization in growth, leading to deformation of the skeleton.
In the first months of life symptoms relate mainly to the skull:
softening in the occipital region, temporal and parietal;
delay in closing the anterior fontanelle (becomes pathological after the fifteenth month of life);
rachitic rosary (between the sixth and twelfth month) hypertrophy of the rib-cartilage junctions;
hypertrophy of the cartilage (in older children) with knots especially wrists and ankles;
bowing of the bones length of the leg and knee valgus.
Osteomalacia occurs in adults with:
muscle weakness;
pain in the back-stretch lumbar spine, pelvic girdle and thighs;
unsteady gait and brittle bones, especially of the spine, shoulders, ribs and basin;
extremely low bone density and the presence of pseudo-fractures, especially the spine, femur and humerus (they radiography);
increased risk of fractures, especially in the hips and wrists. The
hypervitaminosis (excess vitamin D) results in increased intestinal absorption of calcium and bone resorption, hypercalcemia, and decreases serum PTH (amount of parathyroid hormone in the blood, see: calcium and osteoporosis), and loss of calcium homeostasis resulting in:
nausea, vomiting and diarrhea;
hypercalcemia and hypercalciuria, nephrocalcinosis
, cardiocalcinosi and soft tissue calcification.
Excessive intake of calciferol in the diet is extremely unlikely, given the small amount of vitamin D in food, just as you do not know cases of hypervitaminosis due to excessive sun exposure. Instead, you can
intoxication following the administration of calciferol for therapeutic purposes.
food ration made and recommended
Foods rich in vitamin D include:
liver, fish oils, some marine fish (herring, salmon, sardines), smaller amounts are present in eggs, butter and milk.
Almost all vitamin D is synthesized in the skin, so it is recommended that adequate exposure to sunlight, particularly for the elderly.
Under normal exposure to sunlight is sufficient to calciferol meet the needs of the organism, however, especially for safety we recommend the following levels of intake:
infants 10 to 25 g;
children 1 to 3 years 10 g;
children 4 to 10 years 0 to 10 g;
girls 11 ÷ 17 years and boys 0 to 15 g;
adults 0 to 10 g, 10 g

BIOLOGY QUESTIONS 1. Difference between prokaryotic and eukaryotic cell.
prokaryotic cells have a simple internal structure, the DNA is located in the region the cytoplasm (nucleotide) and lacks the membrane, organelles are not present, replaced by ribosomes, which are responsible for protein synthesis.
Eukaryotic cells have an internal structure more complex, the DNA is contained within the nucleus surrounded by a membrane called the nuclear membrane, while the organelles are immersed in the cytoplasm.
2. The kingdom of fungi.
in the Mushroom Kingdom nourishment is absorbed through cell membranes, this process is called nutrition absorption. The cells that compose them are eukaryotic cells and can be unicellular or multicellular.
3. Cell immersed in a solution rich hypertonic glucose: describe the steps of substances through the membrane.
Water tends to move out because the second gradient, and the glucose enters the cell through the cell membrane.
4. What are enzymes? How are synthesized in the cell?
Enzymes are proteins that allow the occurrence of almost all chemical reactions in biological systems, acting as real biological catalysts and are synthesized in the ribosomes.
5. Describe the cell in mitotic metaphase.
During mitotic metaphase sister chromatids are aligned on an imaginary equatorial plane and are crossed by microtubules that attract them to each other on one side and on the other.
6. Run the following intersection: AaBb X AABB
F1
1:2:1:2:1:1
7. What are the effects of crossing-over in crosses with genes associated with? You also do an example.
The effect of crossing-over is that of recombination because the two chromatid exchange portions of DNA, generating new chromosomes that have a different combination of genes. In the case of related genes is a rare phenomenon, but still possible.
EXAMPLE: Crossing-over between GL and vr: Gr and vL
8. How likely is it that a child born by a group 0 A father and a mother B? And that led to two more group 0?
The mother may have had parents B B is the presence of only one X chromosome, while the chromosome in the female patient may be accompanied by a sound and then there is a compensation. In Drosophila
the character is sex-linked eye color is according to this scheme:
All male specimens have red eyes.
All female specimens have red eyes.
All specimens are males with white eyes (mutant).
10. Characteristics of human gametes
The female gametes contain the human X chromosome (omogametico it comes to sex), men's rights to X or Y (eterogametico talking about sex). The sex of the unborn child depends on which fertile male gamete cell egg: if Y is born a male, if X is born a girl.
11. Specifying the meaning of autotrophy through what mechanisms is realized? The
autotrophy and nutritional status of an organism capable of synthesizing its own organic molecules from inorganic materials and using energy not derived from organic substances. They are autotrophic, for example, all plants which, through the process of photosynthesis, are able to synthesize organic compounds from inorganic substances: carbon dioxide and water through the electromagnetic energy of solar radiation. They are also autotrophic algae and many bacteria.
12. Mendel because he needed to do to get a lot of crosses its results? What would happen if she used only a few plants?
Mendel was obliged to work with multiple copies of peas because he was aware that to get results that would allow a correct calculation of the probability would need to rely on many cases and not only watched the first generation, but the second and so on, to be able to distinguish clearly between the lines as well. If he had not worked with thousands and thousands of plants making them match as he wished, he would have obtained a few combinations that would have been the result of chance and could not allow him to make laws that are still valid for the calculation of probability.
13. The difference between sex cells and sex chromosomes.
The sex cells are the gametes: male (sperm) and female (egg). The sex chromosomes are the 23rd pair of sex cells that are X and Y in humans and XX in females. From this combination is born or a male (XY) or female (XX)
14. Membrane proteins: structure and functions.
proteins (integral) membrane act as carriers for transporting molecules in two directions: on one side of the cell membrane. Those are called protein channels that usually allow the passage of small ions such as Na + or Ca + + and are immersed in the phospholipid bilayer, so that through it all; called carrier proteins are those with binding sites and bind to specific molecules of great dimensions.
15. What is a genetic map and how it was done?
The genetic map is the representation of distance between genes, based on data from genetic recombination. And this occurs due to crossing-over, which changes the genetic make phone by simply interchanging sections of chromosomes in meiosis.
16. How do I recognize a sex-linked gene? Write an example of intersection.
recognize whether a gene is sex-linked characteristic that identifies whether the gene will be forwarded to the next generation and is manifested in a of both sexes.
17. Write the possible blood groups of children produced by a group A mother and a father of group AB.
The mother of blood group A may have parents A
18. Describe a human cell in telophase of meiosis II
The human cell in meiotic telophase II is a cell with 23 chromosomes each.
19. Run the following intersection: AABB X aabb
F1 1:1
20. Benefits of Using Drosophila as a genetic model? What is your situation chromosome?
Morgan found in the sample of Drosophila several advantages including: sheet prolific (each intersection produces around 100 individuals) with the possibility of two new generations of each month (rapid generational turnover) and the characteristic four pairs of chromosomes have large easy to analyze, in XY male and XX in female.
21. The kingdoms of the living world
The kingdoms of the world that are living animals (living things which feed internally), vegetable (living autotrophs then transform solar energy into their constituent cells and photosynthetic), fungi (living things that absorb nutrients through cell membranes external), protists (eukaryotic unicellular beings, such as protozoa and amoebas), Monera (prokaryotes living as a simple blue-green algae or bacteria).
22. Difference between active transport and facilitated diffusion. Glucose can be used both modes to enter the cell: in situations where using one or the other way?
Facilitated diffusion is taking place through the passage to the channel proteins, which allow the passage of polar molecules, large or small, is along the gradient. The active transport is the one that requires energy that is the use of ATP and is also called "induced" and occurs against the gradient. Glucose use both of them but most will move through the channel protein when there is a lower concentration of glucose inside the cell and hypertonic condition occurs in the exterior of the cell and will act according to the gradient, while it moves through the active transport when there is a lower concentration inside and isotonic condition occurs within the cell and acts against the gradient.
23. Characteristics of cells produced in meiosis in Drosophila.
cells produced by meiosis in Drosophila are large cells that contain four pairs of chromosomes: three autosomes and one eterocromosomi: male XY and female XX.
24. Run the following intersection: AABB X aabb
F1
1:1:1:1
25. Role of DNA within the cell. What produces an abnormal gene?
The DNA is responsible for synthesizing proteins and to transmit the genetic heritage from one generation to another. An abnormal gene is produced by an abnormal protein, for example with a single amino acid.
26. Structure and function of mitochondria
A mitochondrion is a cellular organelle present in all cells and are Eucharists organelles in the cytoplasm, or organelles involved in the cellular respiration, consisting of respiratory enzymes. They consist of two membranes: the inner membrane and outer membrane, the space between these two membranes is called the intermembrane space. The space bounded by the inner membrane is called the mitochondrial matrix, inner membrane extends into the matrix, forming folds called cristae mitochondrial respiratory enzymes are concentrated here.
27. What results would be obtained in Mendel's F1 dihybrid experiment with if there was incomplete dominance in both pairs of genes? Write the intersection using the genetic symbols.
If Mendel had crossed two copies to incomplete dominance in F1 would have obtained a specimen with intermediate characteristics.
GGLL vvrr X → A → GvLr pea with a colorful mixture of yellow and green and a roughness less pronounced.
28. Give all possible genotypes of the parents of a child with blood group A
Parents should have blood group A arrange themselves in a totally random.
30. How can I come to know that two genes are associated? As an example
are called genes associated with those usually found on the same chromosome. It is noted for example in GL (yellow-smooth) and vr (green-wrinkled).
31. Difference between prokaryotic and eukaryotic cells (GIA 'REPLY TO QUESTION 1)
32. Membrane proteins: structure and functions (GIA 'REPLY TO QUESTION 14 °
)
33. How can I recognize in a population with a sex-linked disease? Write an example of cross
I can recognize it because it will present more on the sample of males, the presence only one X chromosome While it will be less frequent in the sample of women for the presence of two X chromosomes, and then to compensate.
EXAMPLE:
[*= sick] [x = recessive] [X = dominant]
If a woman is the man with x * X which is coupled XY
The child will be born:
a carrier female ( Xx *)
male patient (X * Y)
healthy female (XX)
healthy male (XY)
34. E 'fair to say that the DNA consists of a sequence of genes? Explain.
The definition of DNA as "gene sequence" is partially correct. Suffice it to say that DNA is made up of certain genes follow one another without necessarily being close to each other, but with the ability to distance himself also a lot of space. This "absence" of genes for some stretches of DNA is always "presence" of DNA, but still do not know its exact function, for the most part believes that it serves to coordinate the action of genes in DNA.
35. What are vesicles in the cell? Make an example.
From the end of the smooth endoplasmic reticulum vesicles detach going to fuse with the membrane dell'organulo specific target, depending on the contents of the vesicle. The vesicle membrane becomes part of the target and its contents dell'organulo are secreted outside, or exposed on the membranes if they are anchored to them.
An example is the Golgi apparatus that receives the vesicles of the ER, with amendments and are incorporated into new vesicles that are destined for other areas of the cell, forming a new plasmatic membrane or which discharge their contents outside.
36. The sodium-potassium pump
The sodium-potassium pump is a special case of active transport across the cell membrane that needs energy, and ATP, which acts against a concentration gradient, in which process the Na + out and K + enters the cell using just the energy derived from hydrolysis.
37. Difference between probability and frequency: an example.
The probability of an event is the ratio between the number of successes at the event and the number of possible cases, provided that they are all equally likely. The frequency is instead a repetition of a given event in a certain frequency of time.
Example:
Mendel's experiment has probability calculations and records of attendance. So we know that Mendel considered the probability as the ratio of 3:1 in the F2 and the frequency of repetition of this event as an exact number of times over a given period of time.

39. The cell in prophase of meiosis I. In
cell in prophase of meiosis I, the pair of chromosomes form the tetrads and is experiencing the phenomenon of crossing-over, ensuring a mutation in the gene pool with the mutual exchange of DNA between two chromosomes.
40. The way in which the character of stature is inherited in humans? Explain.
The character of stature is spread across multiple genes and therefore the sum of these genes is high intermediate.

Cardboard Luggage Box
I've decided.
This year is good.
pv I'm getting married later than 31/12.
There are many good reasons to do so.
The first is that tight I would be god.
The second is that I would be really tight with God.
I could list more, for example, see my friends in mezzotight stay with God, but of course one step below ...
All celebrated the first 18 hours, ça va sans dire!
And then today, if not done for a: "I can meet my wife" 're not really anyone. Even
the most miserable now has a wife.
The trend of the moment is the wedding.
The single is now outdated, too nineties.
A little 'how to listen now "Smells Like Teen Spirit", the real revolution is reassessed Toby Lightman.
\u0026lt;time say he was a poet who could speak
d'amore
What does it matter if one dies at the end
It can no longer speak of te>>
