Terms in this set (101)
1. The body plan of a triploblastic organism that lacks a acoelomate
body cavity is best termed:
2. A sense organ of equilibrium seen, for example, in statocyst
jellyfish is a:
3. The primary function of the excretory system in most removal of metabolic waste and osmoregulation
organisms is this:
4. A compound body section resulting from the fusion of tagmata
two or more segments:
5. When animal bodies are comprised of serially metamerism
repeated parts, this is termed:
6. In this type of reproduction offspring develop inside an oviparous
egg that is laid outside of the female body:
7. This term is used to describe the condition of having a cephalization
distinct head region:
8. Flukes are a member of which animal phylum? platyhelminthes
Class Coccidea contains an organism that can be a toxoplasma gondii; avoid undercooked meat and cat litter
serious threat to a developing fetus during pregnancy if a
woman is receiving an initial exposure. What is this
organism? How can it be avoided?
, 10. What is the selective advantage of radial symmetry? allows organisms to recieve stimuli from all directions
When one plane can divide an organism into equal left bilateral symmetry
and right halves, the animal is said to have this type of
symmetry:
12. Alternate waves of contraction are called: peristalsis
This species concept is defined as an irreducible phylogenetic species concept
grouping of organisms distinct from other such groupings
and within which there is a pattern of ancestry and
descent. This species concept is the one that results in the
greatest number of recognized species.
14. Shedding of the outer cuticular layer is also called: ecdysis
15. What is the excretory/osmoregulatory organ in adult antennal glands
crustaceans?
What type of roundworm penetrates skeletal muscle Trichina worms (rare in US)
cells, causing them to become nurse cells for the
parasite? Are cases in the US common?
The evolutionary advantage specifically of the glochidia attaches to fish gills
glochidium larvae seen in some bivalves (as opposed to
general advantages of larval forms) is:
18. Appendages that have two branches extending from biramous appendages
the protopod are termed:
19. The evolution of a series of structures all similar to serial homology
each other but modified for different functions is:
This species concept is a single lineage of ancestor- evolutionary species concept
descendant populations that maintains its identify from
other such lineages and has its own evolutionary
tendencies and historical fate:
21. Character similarity resulting from common ancestry is homology
termed:
22. The type of tissue that covers an internal or external epithelial tissue
surface:
23. In Linnaean taxonomy, which would have the greatest a class
number of recognized species, a class or an order?
