Amoeba sisters video recap: Genetic Drift
Sunny_sXe [5.5K]

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.

What types of materials are expelled from cells during exocytosis?
alex41 [277]

Large molecules such as hormones materials are expelled from cells during exocytosis

<u>Explanation:</u>

The materials inside the cells are transferred to the outside of the cell and this manner is termed as  Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.

For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.
