Answer to Question 1

C
Feedback:
Interleukins are chemicals produced by T cells to communicate between leukocytes and stimulate cellular immunity and inhibit tumor growth. Immune suppressants block the inflammatory reaction and decrease initial damage to cells. Interferons are naturally produced and released by human cells that have been invaded by viruses. Monoclonal antibodies attach to specific receptor sites and respond to very specific situations.

Answer to Question 2

B
Feedback:
The G1 phase lasts from the time of stimulation from the resting phase until the formation of DNA. During this period, the cell synthesizes substances needed for DNA formation. Mitotic spindles are produced in the S phase; rest is accomplished in the G0 phase; and reproduction is in the M phase.
