Which of the Following Describes Adaptive Immunity

Question

Which of the following describes adaptive immunity?
A)It is a general response to pathogens.
B)It does not change over time.
C)It is the basis for vaccines.
D)It is a general response to pathogens and does not change over time.

Accepted Answer

Adaptive immunity is a specific response to a particular pathogen that develops over time after the immune system encounters the pathogen. This type of immunity provides long-lasting protection against future infections and is the basis for vaccine development. Therefore, the best choice is C, which correctly identifies adaptive immunity as the basis for vaccines.
