Answer:
Because natural selection selects for it. Thus it persists.
Explanation:
You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.
Genetic. And it allows for more fish to be created and living freely
In my opinion we would not have clouds because the clouds is our water vapor
Answer:
Option C) Feedback inhibition
Feedback inhibition is a regulatory mechanism in which the end product of a metabolic pathway inhibits an enzyme that catalyzes an early step in the pathway.
Explanation:
Feedback inhibition is a regulatory mechanism in which a biochemical pathway is regulated by the amount of the product that the pathway produces. Thus, it is also known as end-point inhibition.
For example:
The accumulation of ATP inhibits the action of phosphofructokinase, the enzyme that catalyzes the rate-limiting step of glycolysis
