21) While vacationing in a country that lacks
adequate meat inspection, a student ate undercooked ground beef. Sometime later the student became easily
fatigued, and lost body weight. At about
the same time, whitish, flattened, rectangular objects full of small white
spheres started appearing in his feces. Administration of niclosamide
cured the problem. The student had
probably been infected by a
22) Which of the following combinations of phylum
and description is incorrect?
23) An organism is able to extend its feeding
structure(s) through a hole in an exoskeleton.
If the organism were an ectoproct, it would
extend a ________; if a coral animal, it would extend ________; if a bivalve,
it would extend ________; and if a barnacle, it would extend ________.

used by ectoprocts, phoronids,
and brachiopods
25) A brachiopod can be distinguished from a
bivalve by the presence of
26) While sampling marine plankton in a lab, a
student encounters large numbers of fertilized eggs. She rears some of the eggs in the laboratory
for further study and finds that the blastopore
becomes the mouth. The embryo develops
into a trochophore larva and eventually has a coelom. These eggs probably belonged to a(n)

class includes members that undergo embryonic torsion?
28) In a tide pool, a student encounters an
organism with a hard outer covering that contains much calcium carbonate, an
open circulatory system, and gills. The
organism could potentially be a crab, a shrimp, a barnacle, or a bivalve. Which structure below would allow for the
most certain identification?

in members of which class(es)?
32) While snorkeling, a student observes an active
marine animal that has a series of muscular tentacles bearing suckers

39) some members release an anticoagulate

40) A stalked, sessile marine organism has
several feathery feeding structures surrounding an opening through which food
enters. The organism could potentially be a cnidarian,
a lophophorate, a tube-dwelling worm, a crustacean,
or an echinoderm. Finding which of the following in this organism would allow
the greatest certainty of identification?
41) Humans most frequently acquire trichinosis by

with the following larval characteristics: exoskeleton, tracheal system for gas
exchange, and modified segmentation. A
knowledgeable zoologist would predict that its adults probably also would have
43) What is true of echinoderms?
They have an endoskeleton of hard calcareous
plates. Tube
feet provide motility in most 44) A
student observes a worm-like organism crawling about on dead organic
matter. Later, the organism sheds its
outer covering. One possibility is that
the organism is a larval insect (like a maggot). On the other hand, it might be a member of
the phylum ________. One way to distinguish between the two possibilities is by
looking for the presence of
