Question
The secondary antibody response ... A. prevents disease symptoms from occurring. B. occurs because of cytotoxic T cells. C. produces fewer antibodies than the primary response. D. is slower than the primary response.
Solution
The secondary antibody response prevents disease symptoms from occurring. This is because the immune system has already encountered the antigen in the past during the primary response, and thus is able to produce a faster and more effective response. This is not due to cytotoxic T cells, which are involved in killing infected cells, not producing antibodies. The secondary response actually produces more antibodies than the primary response, not fewer. And it is faster, not slower, than the primary response. So, the correct answer is A. prevents disease symptoms from occurring.
