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.

Answer:
<em>Carolus Linnaeus devised the binomial nomenclature system under which the organisms were named using their Genus name and Species name. </em>The Genus name was written first, forward by the species name. The system of binomial nomenclature allowed for assigning a scientific name to all the organisms so that the conversations between scientists could be made easier. For example, humans have the scientific name<u><em>,</em></u><em> Homo Sapiens</em>, where Homo is the genus name and sapiens is the species name.
