Anuta_ua [19.1K]

The thyroid is an endocrine gland that regulates metabolic function through the production of all of the following hormones except: Thyroliberin.

Thyrotropin is a peptide secreted by the anterior pituitary gland that prompts the thyroid gland to release thyroxine. It is also known as thyroliberin and thyroid-stimulating hormone (TSH) Thyrotropin-releasing factor, a peptide located in the hypothalamus of the brain and affecting glandula thyroidea secretion, acts to cause the release of TSH.

In vivo, thyrotropin controls thyroid development favourably. The gland becomes hypoplastic in its absence, either as a result of a pituitary disorder or as a side effect of thyroid hormone therapy, with a reduction in the quantity and size of thyrocytes.

WITCHER [35]

What hormone helps plants move toward a stimulus?

A.)Ethylene

<u>B.)Auxins</u>

C.)Acids

Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance
