Immobilization of bacteria results in the destruction of what?
True or false: antibody structure is identical to the antibody receptor of their progenitor cell.
Along with plasma cells, B cells differentiate into:
IL-2 sets up a positive or negative feedback in order to encourage T cell division?
T cells bind to which type of cells that have found antigens in the lymph?
Antibodies passing from the mother to the fetus via the placenta or breat milk to the infant is an example of what type of immunity?

Antibodies are also called:
Proliferation of other T cells and B cells that have already been bound to an antigen is regulated by which immune cell?
True or false: Cytotoxic cells circulate the body in search of body cells that display antigens to which they have been sensitized.
