Specific immunity is ______ meaning that it is acquired after a(n) ______ event.

Specific immunity is adaptive, meaning that it is acquired after an exposure event.

Explanation:

Specific immunity refers to the immune response that is tailored specifically to a particular pathogen or antigen. Unlike innate immunity, which provides a general defense against invaders, specific immunity develops as a response to specific threats. This type of immunity is often characterized by the presence of memory cells, which enable the immune system to respond more effectively upon subsequent exposures to the same pathogen.

The acquisition of specific immunity typically occurs in two phases: the primary response and the secondary response. The primary response occurs when a person is first exposed to an antigen. During this event, the body recognizes the pathogen and begins to produce specific antibodies and memory cells. After this initial exposure, if the person encounters the same pathogen again, the secondary response is activated more quickly and vigorously due to the memory cells, thus providing a stronger and faster immune reaction.
