Answer:
The correct answer is D. proliferation and differentiation.
Explanation:
Primary immune response occurs due to the first exposure of an antigen to the immune system. The primary immune response is generally delayed by many days because it takes time for B and T cells to become cloned and to proliferate and differentiate.
Then after several days of proliferation and differentiation of activated T and B cells, T cells become effector T cells and B cell becomes plasma cells which then eliminates the antigen. Memory B and T cells are also produced during this process which helps in generating a quick immune response during the second and subsequent exposure of that antigen.
So the correct answer is D. proliferation and differentiation.
<span>If a population is not in Hardy-Weinberg equilibrium that can cause deviations from expectation depending on the assumptions of HW that are violated. If a population violates some of the assumptions (like mutations, migrations and selection) the allele frequencies will change over time. Also, if a non-random mating occurs (like inbreeding), it will cause an increase in homozygosity for all genes.</span>
