PLEASE PLEASE ONLY ANSWER ONLY IF U KNOW! THANKS <3 The beak size in a species of bird is influenced by a gene for which only two alleles exist. The allele that results in a large beak is dominant to the allele that results in a smaller beak. If introduction of a new food source causes the birds with smaller beaks to be better fit to survive, which of the following will most likely happen?

A) The allele for small beaks will become dominant to the allele for large beaks.
B) The bird population will decrease as the recessive allele becomes more common.
C) The birds with large beaks will die out as a result of lack of food.
D) The frequency of the allele that results in small beaks will increase.

In a species of birds, wing size is controlled by a single gene that has only two alleles. The same species lives in two different forests. In one forest, the trees have less foliage and the birds' nests are more susceptible to predation. The large-winged birds are able to flee more quickly. In the other forest, the birds with smaller wings are more obscured from predators. Which of the following best describes the species of birds in the different forests?

A),Selective pressures can cause alleles that are adaptive in one environment to become deleterious in another.
B) The species will eventually develop an intermediate wing size in both populations.
C) The alleles of both populations will undergo directional selection to have the same allele frequencies.
D) If genetic diversity and allele frequencies differ, the species will risk decline.

In a grassland ecosystem, a prolonged drought has caused depletion in food sources for a species of rabbit. Which of the following would allow for the population of rabbits to recover from the drought?

A) Genetically diverse population, with some rabbits able to survive with fewer water resources than usual
B) The population of rabbits must reduce its rate of reproduction to produce only the most fit offspring
C) Individuals of the rabbit population should have less genetic diversity to become more similar and evolve in the same direction
D) Individuals of the rabbit population must develop traits that make them better adapted to fewer water resources
