  1. In a plasma membrane, the "tails" of the phospholipid molecules
    1. project into the intracellular fluid (ICF) and into the extracellular fluid (ECF)
    2. are directed toward the interior of the membrane, away from the ICF and the ECF
    3. constitute a hydrophobic environment that separates the ICF from the ECF
    4. both B. and C.

  2. "Interstitial fluid" is located
    1. inside the nucleus of a cell
    2. inside cells, between the plasma membrane and the nucleus
    3. within the plasma membrane, between the two layers of phospholipids
    4. outside cells, but not in blood

  3. In pancreatic acinar cells, the function of rough endoplasmic reticulum is mainly to
    1. serve as a site for DNA replication
    2. direct the movements of chromosomes during mitosis
    3. synthesize enzymes and package them into vesicles
    4. synthesize lipids and destroy some toxins

  4. Which one of the following does not include a phospholipid membrane as part of its structure?
    1. vesicle
    2. microtubule
    3. Golgi apparatus
    4. endoplasmic reticulum

  5. The structures called _?_ are responsible for the movements of vesicles and chromosomes.
    1. phospholipids
    2. ribosomes
    3. microtubules
    4. smooth endoplasmic reticulum

  6. Which term or process is least directly related to the others?
    1. secretion
    2. vesicle
    3. exocytosis
    4. mitosis

  7. Given the following key: 1=mitosis; 2=interphase; 3=cytokinesis;
    what is the normal sequence of phases in a cell cycle?
    1. 1 - 2 - 3

    3. 2 - 3 - 1
    4. 3 - 1 - 2

  8. During interphase,
    1. DNA is confined to vesicles in the cytoplasm
    2. DNA is scattered throughout the cytoplasm
    3. DNA is highly condensed into chromosomes
    4. DNA is relatively spread out and is visible as "chromatin" in the nucleus

  9. Within a cell cycle, sister chromatids are separated from each other
    1. during interphase
    2. after interphase but before metaphase
    3. during metaphase
    4. after metaphase but before cytokinesis

  10. In the epidermis or in the red bone marrow of an adult, immediately following mitosis and cytokinesis in one stem cell, there are likely to be
    1. two stem cells
    2. two progenitor cells
    3. one stem cell and one progenitor cell
    4. none of the above (there are no stem cells in adults)
