Answer to Question 1

ANS: A
Active immunity occurs either after natural exposure to an antigen or after immunization, not with preformed antibodies or the transformation of T cells into B cells or as a result of receiving immunoglobulin.

Answer to Question 2

ANS: A
Antibodies are produced by plasma cells that mature from lymphocytes, called B lymphocytes (B cells), in response to an antigen. Cytotoxic T cells do not respond to antigens. Self-antigens do not respond to antigens. Helper T cells do not respond to antigens.

These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
