This state is characteristic for recessive traits. For an individual to express a recessive trait, it must have two recessive alleles (one of two or more alternative forms of a gene) of the responsible gene. But, if it has one recessive allele and one dominant allele, it will not have the trait, but he will be called a carrier. So, it seems like the trait "disappeared" but still it is "carried" in the genome. However, if its offspring has two recessive alleles and express the trait, it will <span>seem </span>like the trait "reappeared".

igh levels of cortisol would normally provide negative feedback to the _______. High levels of cortisol would normally provide n
alexandr1967 [171]

High levels of cortisol would normally provide negative feedback to the D)the anterior pituitary and the hypothalamus.

ACTH secretion stimulates the discharge of glucocorticoids (cortisol), mineralocorticoids (aldosterone), and androgen from the adrenal cortex.

Corticotropin-liberating hormone (CRH) is launched from the hypothalamus, which stimulates the anterior pituitary to release adrenocorticotropic hormone (ACTH). ACTH then acts on its target organ, the adrenal cortex.

Cortisol increases blood sugar by way of releasing stored glucose, at the same time as insulin lowers blood sugar. Having chronically high cortisol stages can result in continual high blood sugar (hyperglycemia). this can purpose type 2 diabetes.

spin [16.1K]
The powerhouse of the cell: That is a term used to describe the MITOCHONDRIA, because its main function it to produce energy for cellular activities.

Mitochondria is the host of cellular respiration. This is where the Mitochondria take in glucose and oxygen to produce energy and is distributed all throughout the body as energy-rich molecules of ATP.

which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
KATRIN_1 [288]

An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.

A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.

A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.
