The correct answer is option B, that is, Genetic drift greatly affects small populations, but large populations can recover.
Genetic drift in combination with mutation, natural selection, and migration is one of the most fundamental mechanisms of evolution. Genetic drift refers to a change in the relative frequency of distinct genotypes in a small populace, owing to the chance vanishing of specific genes as individuals do not reproduce or die.
The correct answer is C. Virus.
Virus falls on the gray area which is between nonliving and living things.
Virus is referred to as the small infectious agent which replicates only inside the living cells. Virus can infect life forms plants and animals and microorganisms, for example, archaea and bacteria.
They live in form of independent particles which are referred to as virions. Some viruses can evolve from plasmids.

The Apocrine gland has a direct link to the hair follicle.it is made up of clusters of secretory tubules, which emptied to the hair follicles through the excretory duct. This gland secretions is not continuous, but in periodic fashion. The components of the secretion are protein,lipids, steroids. The secretion is usually odorless and Oily in nature. However this changed when mixed with bacterial or germs on exposure to the skin surface.
At the base of the hair follicles are the sebacious glands which produced sebum. Therefore as the apocrine secretion leaves the secretory ducts, they are mixed with sebum to reach the epidermal surface of the skin.
<span>1. Heterozygous black rabbit will have genotype Bb</span>
2. If a heterozygous black rabbit and a brown rabbit were crossed:
<span>Bb x bb</span>
The offspring will be:
Bb Bb bb bb
Which means that half of them will be black and half brown (50%).
