Textbook Question
Chapter 24, Problem 4TYK
Which of the following best describes the difference in the way B cells and cytotoxic T cells deal with invaders?
a. B cells confer active immunity; T cells confer passive immunity.
b. B cells send out antibodies to attack; certain T cells can do the attacking themselves.
c. T cells handle the primary immune response; B cells handle the secondary response.
d. B cells are responsible for the cell-mediated immune response; T cells are responsible for the humoral immune response.

Antibodies against a specific antigen can be injected into a person to provide passive immunity. For which reason is this NOT as effective as the process of vaccination with that antigen?
Select one:
a.
Injection of antibodies may cause allergic reactions, while vaccination never causes allergic reactions.
b.
Injection of antibodies does not provide long-lasting immunity, and vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells.
c.
Vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells.
d.
Injection of antibodies does not provide long-lasting immunity.
e.
Injection of antibodies does not provide long-lasting immunity and may cause allergic reactions, while vaccination never causes allergic reactions.
Decreased immunity is a symptom of HIV/AIDS. This is caused by which of the following?
Select one:
a. HIV destroys antigens. This decreases the possibility of recognizing pathogens in the future.
b. HIV destroys memory T cells. If the body is infected again, there is no antibodies to fight an infection.
c. HIV attacks the macrophages. Pathogens cannot be destroyed once they enter the body.
d. HIV attacks the helper T cells. This allows pathogen cells to enter the body unnoticed.
Which of the following statements about T cells is false? a. Helper T cells release cytokines while cytotoxic T cells kill the infected cell. b. Helper T cells are CD4+, while cytotoxic T cells are CD8+. c. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. d. The T cell receptor is found on both CD4+ and CD8+ T cells.
