Chapter 24, Problem 4TYK
Which of the following best describes the difference in the way B cells and cytotoxic T cells deal with invaders?
a. B cells confer active immunity; T cells confer passive immunity.
b. B cells send out antibodies to attack; certain T cells can do the attacking themselves.
c. T cells handle the primary immune response; B cells handle the secondary response.
d. B cells are responsible for the cell-mediated immune response; T cells are responsible for the humoral immune response.
