Mutation creates new genetic variation in a gene pool. ... For any given gene, the chance of a mutation occurring in a given gamete is very low. Thus, mutations alone do not have much effect on allele frequencies. However, mutations provide the genetic variation needed for other forces of evolution to act.

Of cells is one of the processes that help multicellular organisms maintain homeostasis
lord [1]

Answer:

<u><em>Reproduction</em></u> of cells is one of the processes that help multicellular organisms maintain homeostasis.

Explanation:

In biology, homeostasis can be described as the capability of an organism to maintain its constant internal environment despite the changes in the external environment.

External factors like pathogens in the environment tend to kill cells in our body like the skin cells and the immune cells. Through the process of cell division, our cells can reproduce and hence, maintain an equilibrium of the internal conditions.

Reproduction of cells also causes growth. Hence, the process of reproduction of cells maintains homeostasis.

aksik [14]

According to the research, the correct option is exocytosis. Insulin is made by pancreatic cells, packaged in small vesicles, and then released into the bloodstream. This describes <u>exocytosis</u> cell transport.

What is exocytosis?

It is the expulsion, by cells, of particles that, due to their size, cannot pass through the cell membrane.

In this sense, it is the process by which different types of molecules contained in a cytoplasmic vesicle of a cell are secreted. Insulin is released to the outside by exocytosis, intervening in the process of glucose entry into cells.

Therefore, we can conclude that according to the research, the correct option is exocytosis. Insulin is made by pancreatic cells, packaged in small vesicles, and then released into the bloodstream. This describes <u>exocytosis</u> cell transport.
