Antigen + TH Antibody Secretion
As represented in the model above, B cells are activated by direct contact with antigens or stimulated
helper T cells (TH). Based on the model, which of the following best describes an outcome of B cell
activation?
a. Activated B cells differentiate into plasma cells and memory cells.
b. Activated B cells stimulate TH cells to secrete antibodies.
Plasma cells produce antibodies that activate additional B cells by a positive feedback
mechanism.
.. Both B cells and TH cells release chemical signals that negatively regulate
antigen-presenting cells.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.

it marks things for degradation via the proteasome. it alters there celluar location.
