Answer:
D. habitat preference
Explanation:
Habitat preference is one of the driving forces for ecological speciation that does not allow interbreeding between the members of a species. In habitat preference, some members of a species have a different preference for habitat than the others. They live in different habitats and do not interbreed. Over generations, these two populations of a species living in different habitats develop genetic variations and interbreed with the members of their own populations only. Gradually, these two populations would develop reproductive isolation and would evolve as two different species.
The correct answer is C. 36
Explanation:
In genetics, a nucleotide refers to the basic units that form genetical material. On the other hand, a codon refers to a sequence of three nucleotides in the mRNA or messenger RNA which are a set of molecules that take genetical information from ADN to the ribosome of the cell. This implies in the case of a 12 mRNA codons there are 36 nucleotides as each of the codons contains three nucleotides which means by multiplying the number of codons by three (number of nucleotides) it is possible to know the total number of nucleotides in an RNA sequence or in this case 12 (codons) x 3 (nucleotides) = 36 nucleotides.

Answer:
Population size of elk increased while the population of aspen tree declined.
Explanation:
As per question, removal of wolves from the system would result in increased elk population due to absence of its predator (wolves). The increased elk population would extensively feed on shrubs and trees like aspen and cottonwood trees. This would cause decline in population size of these shrubs and trees.
