1- Immunodeficiency is a general term that refers to the loss of: A functional mast cells in the body. B immune system function because of genetic mutations. C one or more components of the immune system. D immune system function with age. 2- How does a vaccination help to prevent a disease? A It generates a population of plasma cells that increase the concentration of antibody in the bloodstream. B It generates a population of memory cells that speed up the response to an actual infection. C It establishes defenses that prevent a pathogen from entering the body. D It reduces the severity of symptoms to a disease. 3- Antibodies are formed by which cells of the immune system? A phagocytes B B cells C T cells D natural killer cells E mast cells

Transduction of new virulence factors into a bacterium is called A) Diapedesis B) Opsonization C) Lysogenic conversion D) Antigenic variation E) Phagosome survival
