Question

Quizplus · Accepted Answer

Memory cells are activated by encountering an antigen, which is a molecule that the immune system recognizes as foreign and triggers a response to. Memory cells are a type of immune cell that "remembers" how to respond to a specific antigen if it is encountered again in the future, leading to a quicker and more effective immune response.
