question
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?

question
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.
answer
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.

question
Behaviors are diverse and important for survival and reproduction. Some behaviors are learned, such as the species-specific song of a yellow warbler which is different from the song of a blue-winged warbler. Other behaviors are innate, such as a female cat in heat urinating more often and in many places to attract a mate or honeybees do a "dance" that indicates the distance and direction of a food source when they return to their hive. Which of the following statements supports the idea that behaviors are important in survival and therefore affect natural selection? A) Learned behaviors may not necessarily increase fitness. Baby warblers can learn the song of another species. B) Innate behaviors are the result of selection for individual survival and reproductive success. C) All behaviors are survival mechanisms that increase reproductive fitness by increasing mutation rates. D) Both innate and learned behaviors are entirely based on genes inherited from parents.

C) Females reproduce by parthenogenesis, which means they produce offspring from unfertilized eggs so the males are not needed. D) Within the ground squirrel population, males leave the area of their birth and are replaced by new males, thus maintaining genetic diversity in the population.
