7) A cage containing male mosquitoes has a small earphone placed on top, through which the
sound of a female mosquito is played. All the males immediately fly to the earphone and go
through all of the steps of copulation. What is the best explanation for this behavior?
A) Copulation is a fixed action pattern, and the female flight sound is a sign stimulus that
initiates it.

it.
C) The reproductive drive is so strong that when males are deprived of females, they will attempt
to mate with anything that has even the slightest female characteristic.

17) During a field trip, an instructor touched a moth resting on a tree trunk. The moth raised its
forewings to reveal large eyespots on its hind wings. The instructor asked why the moth lifted its
wings. One student answered that sensory receptors had fired and triggered a neuronal reflex
culminating in the contraction of certain muscles. A second student responded that the behavior
might frighten predators. Which statement best describes these explanations?

A) listening to adult sparrow songs during a sensitive period as a fledgling, followed by a
practice period until the juvenile matches its melody to its memorized fledgling song
B) listening to the song of its own species during a critical period so that it will imprint to its own

27) One way to understand how early environment influences behaviors in similar species is
through the "cross-fostering" experimental technique. Suppose that the curly-whiskered mud rat
differs from the bald mud rat in several ways, including being much more aggressive. How
would you set up a cross-fostering experiment to determine if environment plays a role in the
curly-whiskered mud rat's aggression?
A) You would cross curly-whiskered mud rats and bald mud rats and hand-rear the offspring to
see if any grew up to be aggressive.
B) You would place newborn curly-whiskered mud rats with bald mud rat parents and place
newborn bald mud rats with curly-whiskered mud rat parents. Finally, let some mud rats of both
species be raised by their own species. Then you would compare the outcomes.
C) You would remove the offspring of curly-whiskered mud rats and bald mud rats from their
parents, raise them in the same environment but without parents, and then compare the
outcomes.
D) You would replace normal newborn mud rats with deformed newborn mud rats to see if it
triggered an altruistic response.
