Which cells are associated with the humoral and cell-mediated parts of the immune system?

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.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
