5 True/False Question

1. Humoral Immunity → specific immunity produced by B cells that produce antibodies that circulate in body fluids
   

   True        False

2. Vaccine → foreign molecule that provokes an immune response
   

   True        False

3. Antibody → protein in blood plasma that attaches to a particular antigen
   

   True        False

4. Allergy → lymphocyte that matures in the thymus; is responsible for cell-mediated immunity and also plays a role in humoral immunity
   

   True        False

5. Memory Cell → long-lasting lymphocyte formed during the primary immune response that is reactivated on exposure to the same pathogen, quickly producing many clones
   

   True        False
