Answer:C) the sequence of nucleotides in the DNA template
Explanation: During protein synthesis, the nucleotide sequence of a DNA molecule is first copied into a nucleotide sequence of an mRNA molecule, and this takes place in the nucleus. The synthesized mRNA is complementary to the DNA. A DNA has four bases: Adenine, Guanine, Cytosine and Thymine while in mRNA Thymine is replaced by Uracil. The mRNA molecule produced from the DNA is transported to the ribosome where protein synthesis takes place. In the ribosome the nucleotide sequence of the mRNA is then read three nucleotides (codon) at a time to code for amino acids. The amino acid sequence of a protein is determined by the nucleotide sequence of an mRNA and its DNA.
During meiosis, the daughter cell receives half it's alleles from the mother and the other half of their alleles from the father. Typically, the alleles go through independent assortment etc that makes the types of alleles that the offspring will have random.

Natural selection lead to different species when the squirrels were separated, some of them acquired traits better suited for their new environment. This allowed them to survive and reproduce better than others. Over time, each group evolved to display unique traits for their different environments until one species evolved into two.
Explanation:
The speciation in the squirrels due to the barrier in canyon occurred due to this. Such speciation is called allopatric speciation.
Speciation leads to formation of new species from the existing species due to change in their habitat or physical structure.
The squirrels on the two different side of canyon adapted to the habitat they are in. Their reproductive cycles, habitat and adaptation mode has become different due to the change in environment.
The species of squirrels became two as they reproduce and passed on the traits for survival in the environment which they had adapted.
The squirrels have become <em>reproductively isolated</em> also.
Genetic divergence takes place due to natural selection as squirrels arenow two different species.
In both animals and plants, cells produce new cells by mitosis - but they split differently. A cleavage farrow forms in the animal cell and it splits. For the plant cell, a cell plate forms and then the cell splits.
