Which statement about the specific immune response is false? clonal selection creates short-lived effector cells to destroy the specific antigen. clonal selection produces memory cells that are long-lived and can recognize the antigen in the future. it takes about two weeks for memory cells to respond to an antigen. the maximum response from effector cells takes about two weeks after the first time the body has been exposed to an antigen. memory cells divide to produce effector cells when they are exposed to their specific antigen.
