d1i1m1o1n [39]

Answer:

Melatonin

Explanation:

  • Melatonin is the hormone that is produced by the pineal gland in response to the dark and light cycle.
  • The pineal gland is turned on when there is darkness and turned off when there is light.
  • When it's dark, the pineal gland becomes active and produces melatonin leading to an increase in the melatonin levels in the blood and a person starts to feel more sleepy and the levels of melatonin remain in the blood for about 12 hours after which they fall and the state of wakefulness occurs.
  • The levels of melatonin fall sharply in the presence of bright light.
  • Thus, the melatonin hormone is responsible for controlling the sleep-wake cycle.

Drinking alcohol can cause dehydration, which makes the blood hypertonic. Which option best describes the consequences of this h
julsineya [31]

Answer:

Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial fluid hypertonic. This, in turn, draws water out of the cells.

Basically an hype tonic blood has high solute potential,( low water potential)  compare with  the surrounding  plasma  and the interstitial fluid. Thus the interstitial fluid is hypotonic to the blood.

Consequently,water with higher potential moves   from the interstitial fluid medium into the blood by osmosis through the capillary endothelial. This raises the water potential of the blood, lowering the solute potential, thus making it hypotonic to the interstitial fluid; which is now hypertonic(lower water potential ,due to loss to the blood by osmosis).

Since the interstitial fluids is now hyper tonic to the surrounding cells, water moves from the hypo tonic surrounding cells through osmosis into the interstitial fluids. The sequence continues until a stable internal environment is achieved,
