Put the following steps in the process of B-cell activation in cause-and-effect order: Long-lived memory cells remain in the body to respond rapidly if the same antigen appears again The plasma cells produce and secrete large numbers of antibodies A helper T-cell with a complementary T-cell receptor binds the presented antigen The antigen is processed and presented by a class 2 MHC protein The T-cell releases cytokines that activate the B-cell An antigen binds to the B-cell receptors in the...
