Which best describes a gene
motikmotik

Answer;

a segment of chromosomal DNA

Explanation;

A gene is a  hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.

It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins.  However, many genes do not code for proteins.

Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

The anterior pituitary receives hypothalamic input through the portal blood supply. what is the advantage of this type of anatom
kotegsom [21]

The advantage of this type of anatomical relationship is that this enables the pituitary to receive signals before sending hormones to the rest of the body through the blood.

The anterior pituitary, a significant component of the endocrine system, is the glandular anterior lobe that, along with the posterior lobe (also known as the posterior pituitary or neurohypophysis), constitutes the pituitary gland (hypophysis).

Stress, growth, reproduction, and lactation are just a few of the physiological activities that the anterior pituitary controls.

Blood tests that assess hormone levels are frequently used to determine if the anterior pituitary and the organs it controls are functioning properly.

The hypothalamus-hypophyseal portal veins deliver hypothalamic releasing and inhibitory hormones directly to the anterior pituitary gland.

Certain hormones from the hypothalamus bind to receptors on particular anterior pituitary cells, controlling how much of the hormone they generate is released.
