Question

The concept that only the lymphocytes with a specific type of antigen receptor will proliferate when activated by contact with a specific antigen and interleukins is called: A. Clonal selection B. Antibody selection C. Receptor cell expansion D. Interieuken-mediated immunity What substance stimulates B cells bound to a foreign antigen to proliferate? (Use the answer in the book, the notes and figure from class are different - welcome to science!). A. Interleuken 1 B. Interleuken 4 C. Interferon D. Interferon Cells that produce and secrete antibodies into the body fluids are called: A. Plasma cells B. Helper T cells C. Antigen presenting cells D. Monocytes Which creates the stronger and longer lasting immune response? A. Primary immune response B. Secondary immune response C. Tertiary immune response D. Antigen Presenting Cell response During the first exposure to a pathogen, which type of antibody is produced in large quantities first? A. IgG B. IgD C. IgM D. IgE During the second and subsequent exposures to a pathogen, which type of antibody is produced in the largest quantities? A. IgD B. IgM C. IgE D. IgG Antibody mediated immunity is called: A) The reticuloendothelial system B) The immune surveillance system C) Humoral immunity D) Cell-mediated immunity What type of immunity is most effective against intracellular pathogens? A) The reticuloendothelial system B) The immune surveillance system C) Humoral immunity D) Cell-mediated immunity

Explanation / Answer

57: A: Clonal selection occurs when a lymphocyte with special antigen receptor is proliferated only.
58: Interleukin 2 is released by helper T cells to stimulate the clonal selection.
59: A: Plasma cells are the cells that serve to secrete the antibodies in the body fluid.
