Answer to Question 1

D
Feedback:
After being activated, the B cells form memory cells that will produce antibodies for immediate release in the future if the antigen is encountered again. Although lymphocytes, monocytes, and T cells will then join in the battle to destroy the antigen, they do not produce memory cells as the B cells do.

Answer to Question 2

C
Feedback:
This system (i.e., the HPA) also can create complications, especially when a need exists to override or interact with the total system, as is the case with replacement therapy or treatment of endocrine disorders. Interactions with the total system cannot create a negative feedback system, homeostasis, or maximum efficiency. The other options are incorrect.
