with respect to thirst, which is true

Correct Answer: D

Rationale: ACE inhibitors reduce angiotensin II, decreasing thirst in hypovolemia angiotensin II acts on subfornical organ, not just supraoptic nucleus (ADH site). Drinking and ADH differ thirst is behavioral, ADH hormonal. Dry membranes signal hypothalamus (e.g., via osmoreceptors), but angiotensin II's role is primary in volume loss. ACE inhibition distinguishes thirst modulation, key to RAAS-thirst link, unlike site, regulation, or membrane claims.

Correct Answer: A

Rationale: Growth hormone (GH) from the anterior pituitary promotes body growth by stimulating protein synthesis and cell division, unlike prolactin (milk production) or thyrotropin (thyroid stimulation). Though options are cut off, 'A' aligns with GH's role. This distinguishes GH's systemic anabolic effects, essential for development, contrasting with lactation or metabolic regulators.

Correct Answer: A

Rationale: Antidiuretic hormone (ADH) secretion from the posterior pituitary increases with high blood osmotic pressure, signaling dehydration, prompting water reabsorption in kidneys. Blood calcium, oxygen, or glucose levels don't directly regulate ADH calcium affects PTH, oxygen respiration, glucose insulin/glucagon. 'All choices' is incorrect as ADH's osmoregulatory role is specific. This distinguishes ADH's function in fluid homeostasis, critical for preventing dehydration, contrasting with unrelated metabolic or respiratory triggers.

Correct Answer: D

Rationale: Long-term stress boosts lipolysis, gluconeogenesis, and protein breakdown for energy, suppresses digestion not glycogenesis (glucose storage), which insulin drives. 'Digestive activities' (D) fits as incorrect. This distinguishes stress's catabolic shift, critical for resource allocation, contrasting with anabolic or digestive priorities.
