WSU BIO 106 FINAL STUDY SHEET SOLVED
QUESTIONS AND CORRECT ANSWERS
VERIFIED PREP CONTENT
●● Negative Feedback Loop
Answer: A feedback loop that causes a system to change in the opposite
direction from which it is moving
●● Endocrine System
Answer: The system responsible for hormones
●● Steps in a simple pathway
Answer: Reception
Transduction
Response
●● Steps in a cascade pathway
Answer: A stimulus (first messenger) activity on a receptor that is
transduced to the cell interior through a second messenger.
●● What is a tropic hormone?
,Answer: A hormone that has an endocrine gland as its target = a
hormone that controls the release of other hormones
●● Antagonist pair of hormones maintaining blood glucose levels are
named...
Answer: Insulin and Glucagon
●● Insulin is
Answer: The hormone that lowers blood sugar by having it stored as
glycogen in the liver and increasing cellular uptake.
●● Glucagon is
Answer: A hormone that increases blood sugar levels
●● Antagonistic hormones are
Answer: Two hormones that perform opposite function to maintain
homeostasis
●● What provided opportunity for land colonization by animals?
Answer: Climate was warm and uniform, land was barren rock
●● What were the challenges of colinizing land?
, Answer: There was less water, plants dried out, and there was no support
against gravity
●● What animal phylum was the first to colonize the land?
Answer: Sponges
●● What are the 5 specialized functions of arthropod "modified"
appendages?
Answer: Mating, feeding, sensing, waking, and swimming
●● What are the functions of rigid arthropod exoskeleton?
Answer: Support, protection, and contributes to efficient locomotion
●● Specialized gas exchange found in aquatic species
Answer: Gills: They increase surface area for gas exchange, convoluted
outgrowths containing blood vessels covered by a thin epithelial layer.
●● Specialized gas exchange organs in insects
Answer: Tracheal tubes. Help to increase the surface area and volume
area ratio.
●● Evidence that plants played an important role in insect
diversification
