1. Division 2
2. Division 2
I dont know how to explain the other ones.
Answer:
All antigen receptors produced by a single B or T cell are identical and bind to the same epitope.
Explanation:
Epitope or antigen determinant is the specific part of the antigen that is recognized by an antibody or T-cell receptor. During clonal selection, a lymphocyte proliferates and differentiates to form a group of highly specialized cells in response to a specific antigen present in the body.
The result of clonal selection is the formation of a population of identical cells that recognize the same specific epitope of the same antigen. A lymphocyte that undergoes clonal selection gives rise to two major types of cells in the clone: effector cells and memory cells.
For instance, the clonal propagation of B lymphocytes forms plasma cells (the effector cell) and memory cells. The plasma cells synthesize and secrete specific proteins called antibodies. All the antibodies derived from a plasma cell can bind to and inactivate the same specific antigen.
Answer:
A. chemical energy to kinetic energy
B. chemical energy to thermal energy
D. potential energy to kinetic energy
Explanation:
Food produces chemical energy, standing still, potential energy, running kinetic energy and her body warming up is thermal energy(heat energy)
I think it’s listed in largest to smallest order as is.
In determining probabilities all you need to do is count and then divide by the number of results.
It is asking the chances of having green seeds and that's the recessive allele. For recessive traits to be expressed, there can't be a dominant trait next to it because the dominant trait will always be expressed. So the expected result should be yy (two lowercase) if you want the recessive trait to be expressed.
In the Punnett square of the second generation, there is 1 out of 4 yy genotype. So then divide 1 by 4 and multiply it by 100% to get the probability in percent.
So in short, the answer is 25%.
