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:
intrusive igneous rocks cool from magma slowly because they are BURIED beneath the surface extrusive igneous rocks cool from lava rapidly because they form at the surface and the meaning of those words are simple intrusive means inside of something like interior and extrusive means outside which is like exterior
The color that the new generation's offspring show will be red, pink, and white.
The young creation of living things is called an offspring, which can be created by a single organism or, in the event of sexual reproduction, by two organisms. A group of offspring is sometimes referred to as a brood or progeny in a more generic sense.
All of the pink-flowered progeny are produced when a red-flowered plant and a white-flowered plant are crossed. This cross serves as an example of the incomplete dominance of red and white. The mixing of both alleles results in this circumstance. Gene interaction known as incomplete dominance occurs when only one of two alleles of a gene at a locus is fully expressed, frequently leading to an intermediate or distinct phenotype. Additionally called partial dominance.
CRCW × CRCW = CRCR, CRCW, CWCW i.e, red, pink, and white.
The complete question is:
A red carnation is crossed with a white carnation: Neither one is 3 Fonts dominate over the other: This means that when crossed, their offspring can show pink flower The parent generation genotypes are: CR CR and CW CW (RED x WHITE) An offspring showing pink flowers (CR CW) from the parent generation is now being bred with another pink flower (CR CW) What color will this new generation's offspring show?
