Answer:

The correct answer is option C. "pleiotropy".

Explanation:

Pleiotropy is a characteristic that defines a gene that is responsible for the development of multiple traits, which often seem to be unrelated. Sickle-cell disease is an example of a disease caused by the mutation of a pleiotropic gene, resulting in the person developing red levels, blood clots, and strokes. Other example is the disease phenylketonuria, at which the affected person suffers from a mental disorder and reduced hair and skin pigmentation by a single mutation in a single gene on chromosome 12.

Weather can change from day to day, but _____ does not
geniusboy [140]
"climate" does not.

Usually if we comparing "weather" condition with another word, the word would be "climate". Weather is the day to day atmospheric condition, but climate is the overall weather of an area throughout long period of time, such as a decade.

Using it in a sentence, we can see the difference. We would say "the weather today is nice", but we wouldn't say "the climate today is nice". "today" is a short period of time.

During cell division, what definition correctly describes the process of cytokinesis?
emmasim [6.3K]

Answer:

The cell’s membrane separates the cytoplasm, forming two cells.

Explanation:

Cytokinesis is the physical process during cell division that separates the cytoplasm of the parental cell into two different daughter cells. Cytokinesis occurs after the telophase of mitosis. During this process, the cell membrane grows to surround each daughter cell and thus separate them. In animal cells, cytokinesis occurs by a ring of contractile microfilaments that lead to the constriction of the parental cell.
