Questions and Answers
  • 1. 
    A crossover in meiosis is an exchange of genetic material between: 
    • A. 

      Sister chromatids of homologous chromosomes

    • B. 

      Non-sister chromatids of homologous chromosomes

    • C. 

      Sister chromatids of non-homologous chromosomes

    • D. 

      Non-sister chromatids of non-homologous chromosomes

  • 2. 
    Random orientation of homologous chromosomes occurs in ________ of meiosis.
    • A. 

      Prophase I

    • B. 

      Metaphase I

    • C. 

      Prophase II

    • D. 

      Anaphase II

  • 3. 
    Why do homologous chromosomes pair in prophase I and not in prophase II? 
    • A. 

      Pairing of chromosomes requires precision and it would take too much metabolic energy to pair them twice.

    • B. 

      The kinetochores have been used up after separating the sister chromatids during meiosis I.

    • C. 

      The cells are haploid during prophase II and therefore can't pair.

    • D. 

      Meiosis I is more like mitosis than meiosis II is, and so the chromosomes pair up similarly in meiosis I and mitosis

  • 4. 
    The number of chromosomes in daughter cells produced by meiosis is ________ the number of chromosomes in daughter cells produced by mitosis.
    • A. 

      Diploid

    • B. 

      Triploid

    • C. 

      Half

    • D. 

      Double

  • 5. 
    At the end of meiosis I, each daughter cell is:
    • A. 

      Diploid, and each chromosome consists of a single chromatid.

    • B. 

      Haploid, and each chromosome consists of a single chromatid.

    • C. 

      Haploid, and each chromosome consists of a single chromatid.

    • D. 

      Haploid, and each chromosome consists of two chromatids.

  • 6. 
    Which one of the following is absorbed in the gastrointestinal tract without being digested?
    • A. 

      Starch

    • B. 

      Proteins

    • C. 

      Triglycerides

    • D. 

      Vitamins

  • 7. 
    If you suck on a plain piece of bread, it will begin to taste sweet after a few moments. Saliva contains the digestive enzyme ________________, which breaks down starch into ________________.
    • A. 

      Amylase; glucose

    • B. 

      Pepsin; maltose

    • C. 

      Amylase, maltose

    • D. 

      Maltase, glucose

  • 8. 
    If you were able to collect the chyme from the small intestine and isolate its various enzymes, most of the enzymes would have been produced by the:
    • A. 

      Gall bladder

    • B. 

      Small intestine

    • C. 

      Pancreas

    • D. 

      Stomach

  • 9. 
    Arrange these events in the order in which they occur during fat digestion, absorption, and transport:1. chylomicrons enter lacteals2. triglycerides, phospholipids and cholesterol coated with protein3. fatty acids and glycerol packaged into micelles4. bile salts emulsify fats5. lipase digests fat
