Answer to Question 1

1 . Four spermatozoa are produced from each precursor cell in spermatogenesis, but only one ovum is formed from each precursor cell in oogenesis.
2 . Spermatogenesis occurs continually and is carried through to completion in about 2 months, meaning that there is always fresh sperm. In contrast, the oocytes are all formed before birth and remain in a prolonged prophase of the first meiotic division from fetal life until they are ovulated.

Answer to Question 2

True

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).
