Adaptive Immunity Occurs When

Question

Adaptive immunity occurs when
A) death results from pathogen infection.
B) the innate immune response is overly effective.
C) a broad, rapid response is needed to a wide range of pathogens from the body regardless of the specific type of pathogen.
D) the innate immune response fails to eliminate pathogens in the body and virulent infections persist after the initial innate defense response.

Accepted Answer

Adaptive immunity is activated when the innate immune response is not able to effectively eliminate pathogens from the body, resulting in persistent and virulent infections. This leads to the activation of specific immune cells and molecules that can target and eliminate the specific pathogen causing the infection.
