Answer:

Option C, varicella-zoster virus

Explanation:

The synonym for varicella-zoster virus is VZV and it is responsible for causing chicken pox in primary infection and shingles after the reactivation of latent VZV infection

It is a DNA virus that belong to the group of  herpesvirus. All herpesviruses have the capability to persists in the body after primary infection as latent infection. These viruses survive for a short duration in the environment.

Hence, option C is correct.

If cells in the process of dividing are subjected to colchicine, a drug that interferes with the formation of the spindle appara
ra1l [238]

Answer:

Colchicine inhibits the formation of microtubules by inhibiting tubulin, a protein required for microtubule synthesis. Microtubules in the form of spindle fibers during cell division pull the DNA from the center of the mother cell into the new daughter cells. If microtubules are not formed DNA will not move into new cells. Hence new cell formation will be inhibited in the metaphase stage. Thus the correct answer is option D.

In the term 2pq of the Hardy-Weinberg equation. Why is the multiplication by two necessary?
Gnesinka [82]

Answer:

The correct answer is : option B.

Explanation:

Hardy–Weinberg equilibrium is a mathematical model that states that genotype percentage or frequency in a population and allele in a population remains stable or constant to generations if there are no evolutionary influences present.

Hardy Weinberg equation is :

            P²+2pq+q² = 1

Here, p² represents the frequency of genotypes dominant homozygotes (AA) in a population in equilibrium. The term 2pq represents the frequency of heterozygotes (Aa)  as there are two ways of developing heterozygous individuals either dominant from the egg and recessive from sperm or vice versa. and the term q² represents the frequency of recessive homozygotes (aa).  

Thus, the correct answer is : option B.

What other evidence could you use to analyze evolutionary relatedness among gibbons, monkeys, and humans?
AysviL [449]

Since the question is incomplete, the answer will include the generalize ways that can be used to analyze evolutionary relatedness among gibbons, monkeys, and humans.

Answer:

The evolutionary relationship is important to understand the evolution of the organisms. The common ancestors and closely related species of the organisms can be known by study the evolutionary relationship of the organism.

The DNA sequence and the amino acid sequence of gibbons, monkeys, and humans are quite similar with each other. The gibbons and humans have more then 99% DNA sequence similarity. The physical characteristics, cranial capacity and anatomical characteristics of the gibbons, monkeys, and humans are more or less similar with each other.
