What is the primary characteristic of a secondary immune response?

  • A. It is slower and less specific
  • B. It is faster, stronger, and more specific
  • C. It produces only IgM antibodies
  • D. It does not involve memory cells
Correct Answer: B

Rationale: The primary characteristic of a secondary immune response is that it is faster, stronger, and more specific. This is because memory cells generated during the primary response allow for a quicker and more efficient recognition and response to the same antigen upon re-exposure. This results in a faster production of antibodies, a stronger immune response, and increased specificity. Choice A is incorrect as secondary responses are actually faster and more specific. Choice C is incorrect as secondary responses can produce IgG antibodies in addition to IgM. Choice D is incorrect because memory cells are essential for secondary immune responses.
