WILDLIFE BIOLOGY EXAM
QUESTIONS WITH CORRECT
ANSWERS
What are pheromones? - Answer-an externally released chemical cue within species
What are kairomones? - Answer-an externally released chemical cue among species
What are organizational effects? - Answer-permanent change such as development
What are activational effects? - Answer-behavior change like mating behavior
What are progesterones? - Answer-steroid hormones for pregnancy
What are corticosteroids? - Answer-Steroid hormones for stress
What are androgens? - Answer-Steroid hormones for male sex hormones
What are estrogens? - Answer-Steroid hormones for female sex hormones
What is sexual dimorphism? - Answer-Differences between male and female of
same species
What are the two types of sexual selection? - Answer-intrasexual selection
intersexual selection
What is intersexual selection? - Answer-interactions between opposite sex
females fitness is not limited by mate, rather reproductive processes. Male is limited
by access to mates
bright coloration, elaborate ornamentation, vocalizations
What is intrasexual selection? - Answer-interactions between the same sex (fighting)
Tungara Frogs: whines and chucks. Larger males have lower chucks. All males don't
produce chucks because of predators
How do traits appear in natural selection? - Answer-economical, functional, practical.
How do traits appear in sexual selection? - Answer-showy, elaborate, costly, and
wasteful
What is unnatural selection? - Answer-habitat loss, environmental pollution, climate
change, exotic species, emerging diseases
, What is a broad definition of what the endocrine system does? - Answer-broadcasts
to essentially all cells
What are the 2 key features and 2 key structures of the nervous system? - Answer-
fast and highly specific
What are the 2 key structures and the 3 key features of the endocrine system? -
Answer-glands and hormones
slow, widespread, and receptors determine response
more prolonged, widespread responses
Fast responses such as motor control are controlled by what system? - Answer-
nervous system
Slow responses such as growth, development, and reproduction are controlled by
what system? - Answer-endocrine system
Most tissues, like muscles, are affected by both systems. How is this? - Answer-
Muscle movement is controlled by the nervous system, but the ability of the muscle
cell to maintain the nutrients it needs is controlled by the endocrine system
Rest and digest vs fight and flight - Answer-R&D: parasympathetic
F&F: sympathetic
General features of the endocrine secretions include:
gland
hormone
transport
target cell
Hormone: chemical secreted into the blood
Transport: can reach virtually every cell in the body
Target cell: only affect target cell
What are chemical messengers used in? - Answer-Development
Homeostasis
Disruptive events (stress)
Social interactions
What was the significance of the 1840's rooster experiment? - Answer-when both
testes were removed in a normal cock, the comb and wattles were small, no interest
in hens, weak, and no fight behavior were observed.
When a castrated cock had a testis replaced, the comb and wattles were normal, in
showed interest in hens, strong, aggressive, and the testis was larger than the
control cock.
