Biology 172 UH MANOA. Exam 2 Questions With Complete
Solutions
3 major bilateral groups? Correct Answer Deuterostomes,
Lophotrochozoa,
Ecdysozoa
ametabolous Correct Answer growth without major change in
form
amoebocytes Correct Answer digest food particles pulled in
by water current collar cells
ancestral animal resembled? Correct Answer
choanoflagellates
Animal qualities 1. 2. 3. 4. ? Correct Answer (Multicellular
eukaryotes, heterotrophs, cells lack cell walls, bodies held
together by structural proteins-collagen)
annelida traits Correct Answer closed circulatory system.
metameric (repeated body segements)
anurans Correct Answer keratin outcovering, mucus glands.
(frogs etc). closed circ system. 3 chambered heart. separate
pulmonary and body circuits
aquatic tetrapod Correct Answer appear after the kellwasser.
fusion of bones, braced vertebrae, pectoral girdle, dactylyl.
360mya
, Archenteron Correct Answer digestive tube
arthropods Correct Answer 3/4 of all animals. chitin
exoskeletons. functional groups(TAGMATA). open circulatory.
ascaris lumbricoides Correct Answer intestinal parasite, most
common and largest
asynchronous flight muscles Correct Answer allow instects to
beat wings up to 1000 a second. flight is a key innovation in
resource use/sensory development/ nervous system dev
Bilaterian traits Correct Answer bilateral symmetry and
cephalization
Bilaterians Correct Answer all multicellular animals other
than sponges and cnidarians
Blastula, Gastration, Gastrula? Correct Answer Blastula is
hollow ball of cells, gastration the cells fold to form a gastrula
where a digestive tube begins to form and ecto/ectoderms are
created by the folding
C. elegans Correct Answer full genome mapped, most studied
model organism
catch collagen Correct Answer can change between solid and
liquid states
cephalochordates Correct Answer lancets, small filter feeders,
closed circ system
