Which part of the adaptive immune response involves b cells?

Humoral immunity

Explanation:

Adaptive immunity is of two types: cell-mediated immunity and antibody-mediated immunity. Antibody-mediated immunity includes B cells. The function of B cells is to transform into plasma cells which in turn form antibodies. Antibodies are also called immunoglobulins and bind with a specific antigen to generate an immune response. Body fluids or humor include blood and lymph. Since the antibodies bind to the antigens in body fluids (blood and lymph), the antibody-mediated immunity is also called humoral immunity.

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.
