When blood calcium levels increase, the secretion of parathyroid hormone (PTH) decreases. PTH helps regulate calcium levels by stimulating the release of calcium from bones and increasing its reabsorption in the kidneys. When blood calcium levels are already high, PTH secretion is reduced to prevent further elevation.
Parasympathetic stimulation of the intestine increases motility by promoting smooth muscle contractions and enhances digestive gland secretion by stimulating the release of digestive enzymes and fluids.
Acetylcholine is a neurotransmitter in the GI tract (among other places). An increase in acetylcholine activity (also known as cholinergic activity) results in an increase in GI motility and secretion, not a decrease.
An increase in energy input, such as heat transfer from a heat source or mechanical work, would increase the temperature of a substance. This causes the particles in the substance to move faster, leading to an increase in kinetic energy and temperature.

That is a good question! Sweat glands get the nerve supply from the sympathetic trunk. So anatomically they get sympathetic nerve supply. But the neurotransmitter at the target cells is acetylcholine. So functionally or physiologically, the sweat glands get the parasympathetic nerve supply.
The secretion of sebum by sebaceous glands is primarily stimulated by hormonal changes, particularly androgens like testosterone. These hormones increase the activity of sebaceous glands, especially during puberty. Sebum plays a crucial role in lubricating and protecting the skin and hair, helping to maintain moisture and prevent dryness. Additionally, factors such as diet and environmental conditions can also influence sebum production.
Hypoxia-->pCO2 increase-->chemoreceptors are stimulated-->VMC stimulated-->trachyarrythmia

Yes.
the increase in automobile ownership stimulated the oil industry.

Factors that stimulate an increase in ADH secretion include dehydration, increased osmolarity of the blood, low blood volume or pressure, stress, and certain medications. ADH helps the body retain water by reducing the amount of water excreted in urine.
The parasympathetic is stimulatory to stomach , increase the gastric secretion and motility while the sympathetic is inhibitory , decrease the gastric secretion and motility
