The anterior pituitary gland, under the control of the hypothalamus, produces trophic and tropic hormones, which stimulate growth and releasing of other hormones respectively.
Adrenal pituitary hormones are:
· Thyroid-stimulating hormone (TSH) – stimulates increasing the size and number of cells of the thyroid gland and also stimulates the thyroid gland to release thyroxine.
· Adrenocorticotropic hormone (ACTH) stimulates increasing the size and number of cells of the adrenal cortex and stimulates the adrenal cortex to release glucocorticoids, adrenal androgens and aldosterone.
· Luteinising Hormone (LH) and Follicle Stimulating Hormone (FSH)- causes the release of sex steroids from reproductive organs
· Growth Hormone (GH)- promotes lipid and carbohydrate metabolism by stimulating the liver to produce IGF-1 and opposes the action of insulin
· Prolactin-stimulates Secretion of estrogens/progesterone and has a role in milk production (lactation).
The answer is B. The can lose their form/function and become denatured with extreme temperature or pH variations.
Answer:
D. carbon dioxide
Explanation:
An increase of a plant's biomass is the result of photosynthesis. Therefore, carbon dioxide and water ultimately contribute to the huge increase in the pine tree's biomass.

Answer:
Choice C., High blood glucose levels can result from an overproduction of insulin
Explanation:
Blood sugar levels are regulated by two pancreatic hormones—insulin and glucagon. When blood sugar levels increase, insulin is released (beta cells of the pancreas), it binds to its receptors and consequently increase glucose uptake by cells, which effectively lowers blood glucose levels. On the other hand, when blood sugar levels decrease, glucagon is released (alpha cells of the pancreas), it binds to its cell receptors, and causes glucose to be released into circulation, thereby increasing blood glucose levels.
