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.
Bacteria cell has chromosomal and plasmid dna and is prokaryotic (without a nucleus). Animal cell is eukaryotic (with a nucleus).
Bacteria cell has cell wall and cell membrane, but animal cell only has cell membrane.
Bacteria cell has no mitochondria, animal cell does.
Bacteria cell has flagella, animal cell doesn’t.
Answer: April Cashin-Garbutt, MA, reviewed it (Cantab) Collagen is a protein composed up of amino acids, which are carbon, oxygen, and hydrogen molecules. Glycine, Proline, Hydroxyproline, and Arginine are among the amino acids found in collagen. Collagen makes up around a third of the proteins in the human body.

Meiosis differs from mitosis in the number of chromosomes in each ending cell. In addition, one of the purposes of meiosis is to reduce the chromosome number in each cell by half and meiosis contains two rounds of division which is meiosis I and meiosis II and ends with four gametes that are not the same genetically.
