  a. chemotaxis.
  b. endocytosis.
  c. degranulation.
  d. opsonization.

Question 2

Answer to Question 1

ANS: C
Degranulation of mast cells is a major cellular component of inflammation. Chemotaxis is the process of white cell migration. Endocytosis and opsonization are parts of phagocytosis but are not factors in mast cell response.

Answer to Question 2

ANS: C
Opportunistic microorganisms can cause disease if the individual's defenses are compromised. Diabetes, congestive heart failure, and pneumonia are not associated with immunocompromised disorders.
