Some butterflies can ingest toxic chemicals from the milkweed plants they feed on and then canstore those chemicals in their bod
Norma-Jean [14]

Answer:

A) Any butterfly allele that allowed milkweed toxin storage would be likely to persist because butterflies that had it were more likely to survive.

Explanation:

Butterflies are natural preys to birds. Over time, some butterflies evolved adaptive strategy such as developing an allele which enables storage of toxin from milkweed as a form of defense mechanism. This stored toxins repel birds from eating the butterflies having this allele giving rise to the survival of these butterflies overtime. Butterflies that had it are likely to be highly favored for survival against predatory birds, while those butterflies without this allele are likely to be heavily preyed upon by birds.

Explain its normal role and why scientists would regard it as the "guardian of the genome."
Burka [1]
The gene p53, also called the guardian of the genome is located on the 17th chromosome in human genomes.
It was given this alternative name because it has a role in response to damage of DNA molecule and in preventing cancer.
The protein product of this gene stops the replication of damaged DNA, activates proteins that repair the DNA damage and if the reparation proteins fail to fix the damage it activates the process of apoptosis or so-called cell death in order to prevent the damaged cell to proliferate and potentially develop into a tumor.

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.

BRAINLEST SUPER EZ QUESTION Why is ocean water considered a mixture but a cup of water is a pure substance?
devlian [24]

Answer:

Ocean water is a mixture! Salt and water together, makes salt water, since the salt dissolves in it.

Normal water in a cup, though, is a pure substance. Nothing is in it, and its purified, so it is not a mixture.

If it's more than one things, it's a mixture!

I hope this helps!
