1) simple goiter can be prevented by
a. surgery to remove the thyroid gland.
b. removal of the pituitary.
c. administration of acth.
d. administration of insulin.
e. increasing intake of iodine in the diet.
2) after eating eggs for breakfast, you return in the evening, dunk the dirty dishes in
water, and notice the yellow streaks remain "dried on." however, after soaking awhile,
the complex of various egg yolk molecules easily "washes off." what has happened?
a. heating denatured the egg protein molecules, hydrolysis reactions then formed bonds
in the dried egg, and soaking in water eventually resulted in condensation reactions
where water broke these bonds.
b. heating denatured the egg protein molecules, unorganized condensation reactions
then formed bonds in the drying egg, and soaking in water eventually resulted in
hydrolysis reactions where water broke these bonds.
c. the egg monomers were fused to become one polymer, which was easily dissolved by
water back into monomers.
d. the presence or absence of water changes the molecules from hydrophilic to
hydrophobic respectively.
e. the addition of water converted organic molecules into inorganic molecules.
3) red blood cells come in many "blood types" including type a, type b, type ab, type o
[lacking proteins a and b], rh positive, and rh negative [lacking rh+] and many others. if
blood is transfused, the recipient detects any new or "foreign" proteins. these blood type
proteins are
a. in the plasma where they have been secreted by the red blood cells.
b. inside the red blood cell cytoplasm.
c. on the outer surface of the red blood cell membrane.
d. evenly distributed throughout the cell contents and plasma.
e. in the red blood cell nucleus.
4) an oncogene is
a. a viral gene with no relation to the host cell's genes.
b. a mutated form of a proto-oncogene.
c. a bacterial gene that causes cancer in the host.
d. always seen in human cancer cells.
e. a gene that turns off cellular reproduction.
5) which statement is not true about subatomic particles?
a. protons are found in the nucleus.
b. neutrons have no electrical charge.
c. electrons contain much less mass than neutrons.
d. electrons are found in orbitals around the nucleus.
e. all electrons in an atom contain the same amount of energy.
incorrect
6) the history of life on earth can be studied by looking at ___________ instead of
_________.
a. macroevolution, microevolution

c. sexual selection, macroevolution
d. gene flow, microevolution
7) which of these statements is not correct about the flatworms? flatworm(s)
a. embryos are triploblastic.
b. are deuterostomes.
c. have a sac body plan with an incomplete gut.
d. are free-living or parasitic.
e. are in phylum platyhelminthes.
incorrect
8) which statement about taste receptors is not true?
a. taste receptors are chemoreceptors.
b. taste receptors are located within taste buds in humans.
c. taste receptors are found only on the tongue in animals.
d. taste receptors recognize sweet, sour, bitter, and salty sensations.
e. taste receptors generate nerve impulses in associated sensory nerve fibers.
9) edward jenner promoted the use of cowpox infection that was very similar to the
more dangerous smallpox, as a vaccination to provide patients immunity from future
smallpox epidemics. this is an example of
a. passive immunity.
b. active immunity.
c. an inflammatory response that decreased the ige production and increased t cells.
d. developing high levels of complement.
e. developing high levels of interferon although jenner did not realize these diseases
were viral.
10) which of the following fields of study provide useful information for making
decisions about conservation?
a. agronomy
b. veterinary science
c. genetics
d. physiology
e. all of these fields provide useful information for making decisions about
conservation.
11) name the neuromuscular transmitter that is released into the synaptic cleft.
a. sodium ions
b. calcium ions
c. atp
d. creatine phosphate
e. acetylcholine
12) "artery" and "vein" are defined by whether they leave or enter the heart. if they
were defined by whether they carried oxygenated or deoxygenated blood, we would
have to change the name(s) of
a. the hepatic portal vein to a hepatic portal artery.
b. the hepatic and renal systems; they would have to be switched.
c. the pulmonary artery and vein; they would have to be switched.
d. the coronary artery and vein; they would have to be switched.
e. none, since the aorta and vena cava do not have "artery" and "vein" in their name.
