Which cells are associated with the humoral and cell-mediated parts of the immune system?
humoral—b lymphocytes; cell mediated—t lymphocytes
humoral—b lymphocytes; cell mediated—neutrophils
humoral—t lymphocytes; cell mediated—neutrophils
humoral—neutrophils; cell mediated—t lymphocytes

B cells and T cells, respectively.

Explanation:

Humoral and cell-mediated immunity are parts of adaptive immunity, which is acquired by an individual in his lifetime due to exposure of pathogens. Cells involved in humoral immunity are B lymphocytes or B cells. These cells form antibodies to fight against infections.

Cells involved in cell-mediated immunity are T lymphocytes or T cells. These cells release various cytokines that activate other immune cells or kill pathogens directly.

Thus, the correct answers are B cells and T cells, respectively.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;
