d. dendritic cells
e. epithelium.

1–17 All of the following statements are characteristic of secondary immune responses except

completely eradicate an infection.
b. Secondary immune responses are restricted to adaptive immune responses.
c. Memory cells are activated rapidly during secondary immune responses.
