  1. Which one of the following is not a means by which lymphocytes counteract specific antigens?
    1. B cells surround, engulf, and destroy tumor cells ("phagocytosis").
    2. T cells use special molecules to create "holes" in membrane of target cell.
    3. Antibodies attract "complement" which creates holes in membrane of target cell.
    4. T cells introduce special molecules that lead to enzymatic destruction of DNA of target cells.

  2. Generally, large complex molecules such as proteins that are present in the body prior to birth will be regarded as
    1. antigens
    2. antibodies
    3. complements
    4. memory cells
    5. self molecules

  3. The "secondary immune response"
    1. involves "helper T cells" only
    2. involves a longer "lag period" than does the primary response
    3. is provided by memory cells that "remember" a specific antigen
    4. usually leads to rapid production of large numbers of antibodies
    5. both C and D

  4. The most well-documented means by which tumor cells may be destroyed by the immune system is
    1. direct attack by B cells
    2. direct attack by T cells
    3. agglutination (clumping) caused by antibodies
    4. none of the above (there are no documented means by which tumor cells may be destroyed by the immune system)

  5. Antibody molecules are particularly useful in
    1. stimulating B cells to form a clone
    2. neutralizing viruses and toxins present in body fluids
    3. providing long-term immunity against multiple antigens
    4. entering virus-infected cells and destroying the viruses in them

  6. In an adult, which one of the following contains the greatest number of lymphocytes?
    1. bone marrow
    2. blood
    3. lymph nodes
    4. the thymus

  7. Which one of the following is the least likely means by which the immune system may reduce the number of viruses in the body?
    1. The immune system may produce antibodies that "clump" viruses together and neutralize them.
    2. The immune system may use special molecules to create "holes" in the membranes of viruses.
    3. The immune system may destroy cells that are infected with viruses.

  8. Given the following key:
    1 = exposure to antigen
    2 = release of antibodies
    3 = "programming" in bone marrow
    4 = formation of B cell clone by mitosis
    What is the correct sequence in the function of B cells?
    1. 1 - 2 - 3 - 4
    2. 2 - 1 - 3 - 4
    3. 3 - 1 - 4 - 2
    4. 3 - 4 - 1 - 2
    5. 4 - 3 - 1 - 2
