Question 8

A primate called the Aye aye is found only on the island of madagascar. It’s ____ is actually very similar to a woodpeckers because this primate uses its long middle finger to tap on trees and listen for larvae underneath. It then uses that middle finger to dig out the larvae and consumes them. It is active at night and it arboreal. The fossa birds of prey and snakes may eat aye-ayes

Answer 8

niche

Question 9

The kaibab squirrel is a subspecies of the Abert’s squirrel that formed when a small population became isolated on the north rim of the Grand Canyon. Which type of isolation is this an example of?

Answer 9

geographic isolation

Question 10

Male fireflies use specific light patterns to attract females. Various species display their lights differently; if a male of one species tried to attract the female of another, she would not recognize the light pattern and would not mate with the male. Which type of isolation is this an example of?

Answer 10

behavioural

Question 11

of the seven recognized species in genus Magicicada three follows 17 year mating cycle, while four follow a 13 year cycle. While species with a 17 year cycle emerge every 17 years to breed, species with a 13-year cycle emerge every 13 years. In regions where their geographic range overlaps, their emergence coincides once in every 222 years. which type of isolation is this an example of?

Answer 11

temporal isolation

Answer 15

divergent evolution

Question 16

allele frequencies in a population will remain constant unless one or more factors cause those frequencies to change. This is known as the

Answer 16

Hardy-Weinberg Principle

Question 17

Which of the condition is NOT required to maintain genetic equilibrium from generation to generation?

Answer 17

there must be random variation
