When a "new" antigen first challenges the immune system,if the primary immune response produces B cells,what are the fates of those B cells?
I-Some of the B cells become plasma cells that secrete antibodies.
II-Some of the B cells become memory cells and can produce a swifter response if the body encounters that particular antigen again.
III-Some of the B cells secrete chemicals called pyrogens that travel to the brain inducing a fever.
A)just II
B)just I
C)II and III
D)I and II

Quizplus · Accepted Answer

During the primary immune response, some of the B cells become plasma cells that secrete antibodies, while others become memory cells that can produce a swifter response if the body encounters that particular antigen again. There is no evidence suggesting that B cells secrete chemicals called pyrogens that induce a fever.
