1. Fat digestion and absorption involves the following, listed alphabetically:
1) Bile salt
emulsification of fats; 2) Chylomicrons; 3) Lacteals; 4) Micelles; 5) Pancreatic lipase. The
correct sequential order for these, based on order of appearance and activity, is
a. 1, 5, 4, 2, 3
b. 5, 2, 1, 3, 4
c. 4, 1, 3, 5, 2
d. 2, 4, 5, 1, 3
2. A patient can produce antibodies against some bacterial pathogens, but does not produce
antibodies against viral infections.
This is probably due to a disorder in which cells of the
a. B cells
c. natural killer cells
d. T cells
3. A blood vessel in someone is punctured or otherwise damaged.
The following events are
likely to occur, listed at random:
damaged cells together with platelet & blood factors cause prothrombin to transform
II. fibrin fibers trap blood cells in a meshwork (“clot”)
III. platelets autosecrete material which causes adjacent platelets to clump together
IV. thrombin induces fibrinogen to become fibrin
The correct sequence of these events is:
a. IV, III, I, II
b. III, I, IV, II
c. I, IV, III, II
d. II, III, IV, I
4. Consider an ectotherm and an endotherm of equal body size. The ectotherm is more likely to
survive an extended period of food deprivation than the endotherm because
a. the ectotherm is sustained by a higher basal metabolic rate.
b. the ectotherm will expend less energy/kg body weight than the endotherm, and the
ectotherm will invest little to no energy in temperature regulation.
c. actually, assuming equal size, the ectotherm and the endotherm will have the same
d. none of the above are incorrect
