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.

blondinia [14]

Answer:

The resistance of the device is 27Ω

Explanation:

When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.

In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.

Using Ohm's law

R=\frac{V}{I} \\R=\frac{81V}{3A}=27Ω

victus00 [196]

Answer:

Human insulin

Explanation:

The process where by region of a DNA that codes for a particular function is transferred between organisms into cells Is described as gene transfer. This process can be used to enhance the mechanism of producing a gene that is not originally present in such organisms before. Therefore if the gene that code for insulin is inserted into a bacterial vector , the offspring of such bacteria will be able to synthesize insulin in their cell

sladkih [1.3K]

Answer:

B

Explanation:

The distance of the Goldilocks zone ensures that water on the terrestrial planet is maintained in the liquid phase. This is because the distance from the star ensure it receives enough sunlight to keep the planet warm but not too hot that the water exists as vapor. Water in its liquid form is essential for maintaining life like here on earth.
