Answer:
C. disruptive natural selection
Explanation:
Disruptive selection is a type of natural selection in which extreme phenotypes are favored over intermediate phenotypes in a population. Environmental change is a major factor that can bring about disruptive selection. The individuals with the extreme phenotypes adapt well and are able to survive in the particular environment, while those individuals with intermediate phenotypes would hardly survive or be greatly reduced in number.
The gray rock outcrops and the brown soils of the Island favors the survival of mice with brown and gray fur color respectively. The fur colors of these two extreme phenotypes in the population of mice, have helped both varieties against Hawks as their main predators, hence establishing their existence on the Island.

Answer:
mRNA
Explanation:
The messenger RNA also called mRNA is the type of RNA that serves to carry the genetic information from DNA to the cytoplasm. The mRNA is formed by the process of transcription using the DNA template strand.
The mature mRNA enters the cytoplasm and joins with the ribosome. The nucleotide sequence of mRNA is translated into the amino acids sequence of polypeptides. The nucleotide sequence of mRNA is read in the form of triplet genetic codes by tRNA.
