Question

16 of 25

Which of the following describes a fever?

Fever is a specific response to a specific antigen.

Question

22 of 25

What is the function of the helper T cell?

It produces antibodies.

It is a descendant of an activated B or T cell that stays in the body for years after the initial infection.

It resides in the lymph nodes and evolves into a plasma cell.

It engulfs and digests antigens and then presents parts of the antigen on its plasma membrane.
