Answer: The correct answer is -

D) have a mutation that allows them to survive treatment with medication.

Explanation -

Natural selection is a theory of evolution that was proposed by Charles's Darwin. According to this theory, organisms that have a beneficial gene variant (allele) to enhance their survival or that are capable of better adapting in their changing environmental conditions, will survive and produce large number of offsprings through reproduction.

Option D) in this question correctly correlates this theory as the mutation in the organism is enhancing its rate of survival.

Thus, option D) is the right answer.

Answer:

i dont know exactly what characteristic it would be

Explanation:

the variation of the beak shape was because the islands had diffrences to them. so on some of the islands the nuts would be bigger or smaller. The birds had to adapt to this so their beaks changed when you looked at the diffrent birds on the diffrent islands. The finches would have big beaks on one island because the nuts were bigger and they need food, but on another island the nuts were smaller so the finches on that island would have a smaller and more narrow beak. so bassiaclly the diffrences were because the birds adapted over time so they could use their beaks to properly eat.
