Question

1. promotes the secretion of hormones from the ovaries and testes 17. process of production of milk. 18. a hormone that lowers the blood glucose level in the body. 19. a hormone the increases the blood glucose level in the body. 20. a hormone that maintains pregnancy.

Explanation:

To solve these questions, we analyze each one based on endocrine system knowledge:

Question 17 (Process of hormone production)

The process of producing hormones is called hormone synthesis (or more specifically, in the context of glands, it's the process by which endocrine glands generate hormones, often involving biochemical pathways like protein synthesis for peptide hormones or steroidogenesis for steroid hormones). But the term for the process of production of hormones is hormone secretion (or "synthesis and secretion"). Wait, the question says "Process of production of hormones"—the term is hormone biosynthesis (or simply "hormone production" process, but the standard term for the process of making hormones is hormone synthesis or "hormone production" pathway. However, in some contexts, "hormone secretion" includes production + release, but the process of production (making) is biosynthesis.

Question 18 (Hormone lowering blood glucose)

The hormone that lowers blood glucose is insulin (secreted by the pancreas’ beta cells; it facilitates glucose uptake into cells, glycogen synthesis, etc.).

Question 19 (Hormone increasing blood glucose)

Hormones that increase blood glucose include glucagon (secreted by pancreas’ alpha cells, stimulates glycogen breakdown) or epinephrine (adrenaline) or cortisol (long - term). The primary one for this basic question is likely glucagon (or "glucagon" is the key one here, though cortisol/epinephrine also work, glucagon is more direct for glucose increase via glycogenolysis).

Question 20 (Hormone maintaining pregnancy)

The hormone that maintains pregnancy is progesterone (secreted by the corpus luteum initially, then placenta; it supports the uterine lining and inhibits uterine contractions) or human chorionic gonadotropin (hCG) (maintains the corpus luteum to secrete progesterone in early pregnancy). But the main hormone for maintaining pregnancy (especially the uterine environment) is progesterone, though hCG is also crucial in early stages. For a basic answer, progesterone (or "hCG" can also be acceptable, but progesterone is more about maintaining the pregnancy environment).

Final Answers (matching each question):

1. Hormone biosynthesis (or "hormone production" / "hormone secretion" - depending on context; the term "hormone synthesis" is precise for production)
2. Insulin
3. Glucagon (or Epinephrine/Cortisol, but Glucagon is primary for glucose increase from glycogen)
4. Progesterone (or hCG)

(Note: If these are fill - in - the - blank questions, the standard answers are:

1. Hormone synthesis (or "hormone production")
2. Insulin
3. Glucagon (or "Adrenaline" / "Cortisol" but Glucagon is most direct for this basic level)
4. Progesterone (or "hCG" - Human Chorionic Gonadotropin))
