Question

Quizplus · Accepted Answer

The major advantage of having a system of adaptive immunity is that it enables a rapid defense against an antigen that has been previously encountered. This is because the immune system can quickly produce specific antibodies or immune cells that recognize and target the antigen, speeding up the process of eliminating the pathogen from the body. This is the basis of immunological memory, which allows the immune system to mount a faster and more effective response to subsequent infections by the same pathogen.
