6.

What is the function of antibodies within the immune system?

a)

Antibodies kill off any antigen that enters the body.

b)

Antibodies are only made when you are given a vaccination for specific antigens.

c)

Antibodies bind to specific antigens to flag for destruction.

7.

How do Killer T-Cells differ from Plasma B-Cells?
