Immunology Practice Exam Questions
With Correct Answers
Infection |with |HIV |results |in |which |of |the |following?
A. |Immunodeficiency
B. |Hypersensitivity |disease
C. |Allergic |reaction
D. |Autoimmune |disease
E. |Genetic |disorder |- |CORRECT |ANSWER✔✔-immunodeficiency
Indicate |whether |the |statement |is |true |or |false |and |explain |why.
Booster |shots |are |necessary |because |repeated |exposure |to |an |antigen |builds |a |stronger |
immune |response. |- |CORRECT |ANSWER✔✔-True, |each |time |the |body |is |exposed |to |an |antigen
|the |adaptive |immune |response |remembers |the |antigen |a |litter |better |each |time. |Therefore, |
with |each |subsequent |exposure |the |immune |response |reaction |time |is |faster |and |can |more |
rapidly |and |easily |adapt |to |fight |the |antigen.
Indicate |whether |the |statement |is |true |or |false |and |explain |why.
