Answer:
Genetic drift is simply a change in the frequency of alleles in a population.
Like shown in the comic A, there are different genes present on chromosomes. All of these genes are made up of a pair of alleles. These alleles determine the genotype and the resulting phenotype of an organism.
If none of the alleles is favored by the environment, then a population will have equal no.of all the variant forms of a trait. Like shown in the comic B, both the green and the grey animals are favored equally.
But if natural selection occurs and one form of the allele variant is favored, then a genetic drift will occur. Most of the organisms will have the alleles which are favored by the environment. Like shown in Comic C, where the grey alleles are favored more than the green alleles.
The hypodermis (subcutaneous tissue) is the innermost layer of skin in your body. The dermis is the middle layer. The epidermis is the outermost layer.
<h3>What does the subcutaneous layer consist of?</h3>
Subcutaneous tissue is the deepest layer of your skin. It's made up mostly of fat cells and connective tissue. The majority of your body fat is stored here. The subcutaneous layer acts as a layer of insulation to protect your internal organs and muscles from shock and changes in temperature.
<h3>What is not found in dermis?</h3>
The answer is C fat cells. So the dermis is between the epidermis and the subcutaneous tissues.

Fungi reproduce by releasing tiny spores which grow into new fungi.
Answer:
DNA helicase
Explanation:
DNA helicase unwinds the DNA strands by breaking the hydrogen bonds down at the center of the strand. this process begins in the replication fork of the DNA strand
geological isolation, if the birds that develop mutations do not have any competition they can survive.
