Answer:
What amino acids do is aid growth, cell replacement, and cell and tissue repair.
Explanation:
Amino acids are the units that make up the structure of proteins, necessary for the structure and function of living beings.
Due to the structural function of proteins —capable of forming tissues such as muscle and collagen that are present throughout the body— it can be said that <u>amino acids contribute to growth and development. In addition, amino acids and proteins can assist in cell renewal and repair of cells and tissues</u>.
The other options do not correspond to functions of the amino acids:
- <u><em>Help the body use certain vitamins and create cell energy </em></u><em>is a function of the lipids.
</em>
- <u><em>Provide energy and help cells get energy from other nutrients</em></u><em> is a function of carbohydrates.
</em>
- <u><em>Turn carbohydrates into proteins, fats, and fatty acids</em></u><em> is not a amino acid function.</em>
Answer:
D. Decreasing vessel diameter
Explanation:
Cardiac output is the amount of blood pumped per unit time by heart. Increased cardiac output corresponds to increased blood pressure which will result in increased blood flow. In vasodilation the smooth muscles within the blood vessels relax making them wide hence decreasing vascular resistance leading to more blood flow. Decreased blood viscosity will also decrease the resistance to blood flow.
Decreasing vessel diameter will not increase the blood flow, it will rather restrict it because there will be more resistance to passage of blood due to small space.
Answer: Physical movement and energy

Answer:
c. The abnormality is in the thyroid gland itself.
Explanation:
Primary hypothyroidism arises from a pathology in the thyroid gland itself and occurs when the thyroid gland is not able to perform one of its many physiology. Secondary hypothyroidism starts at the level of the pituitary gland and results from under secretion of TSH. TSH is needed to trigger the release of the T3 and T4 stored in the thyroid gland. Tertiary hypothyroidism is caused by a decrease level of the TRH from the hypothalamus. This reduced level, in turn, reduces TSH and thyroid hormone levels in the blood, hence in the body and the patient suffer the symptoms.
