Answer:
The changes in the frequencies of blue and green eye alleles can not be predicted since genetic drift is a random event.
Explanation:
Genetic drift is the change in the allele frequencies of a population caused by some chance event. The effect of genetic drift is more pronounced in smaller populations since random events cause changes of greater magnitude in a small population. It can cause the complete loss of an allele from a small population.
According to the given information, the frequencies of alleles for green and blue eyes are changed by genetic drift which in turn would produce random evolutionary changes Either of the alleles may be eliminated from the population irrespective of the fact that the allele is beneficial or harmful. Thus, genetic drift would change the frequencies of the allele in an unpredictable manner.
This makes solution hypertonic which helps in reduction of inflammation in the surrounding cells.
<h3><u>Explanation:</u></h3>
The phagocytosis is the process by which white blood cells take in in different parts of of the pathogens that are invading the human body as well as secreting different toxins which helps them to survive better inside their hosts. Thus these white blood cells takes in the pathogens and thereby digests them and produce the excretory products which are then excreted in the interstitial space. Excretory products from thousands of white blood cells accumulate in the blood plasma and thereby it increases the concentration of blood plasma and makes it hypertonic with respect to the tonicity of the surrounding cells.
In the meantime due to the infection, the surrounding cells are inflamed. The hypertonic blood plasma thereby draws out different amounts of water from the cell and reduces the inflammation to certain extent.

Answer:
C. E site
Explanation:
Translation is the process by which mRNA is converted into polypeptide chain. Translation machinery has three binding slots for tRNA : A, P and E. Any incoming tRNA encounters A, P and E site in that order.
When a new tRNA (#1) carrying the next amino acid (here, lysine) comes, it enters the A site. Peptide bond is formed between lysine and the already existing amino acid on the growing polypeptide chain on the preceding tRNA (#2). Once lysine is added to the polypeptide chain, the entire chain moves to tRNA #1 which makes tRNA #2 empty. Meanwhile, the machinery moves forward. As a result, tRNA #1 slides to P site and tRNA #2 slides to E site. The A site is empty now and can receive another tRNA.
Blood like most liquids, is incompressible, and the equation of continuity in the form of
A1v1 = A2v2 can be applied. We also have to use the fact that the area of a circle is πr2
unobstructed volume flow rate (πrU2)vU = (πrO2)vO obstructed volume flow rate
The ratio of radii then is given by: rU/rO = sqrt[vO/vU] = sqrt(3) = 1.7
