The correct answer is - 4. a flash flood.

Most of the people in the world live on the coasts or very close to the coasts in the places with very low elevation. If the circumstances are right and something manages to trigger a sudden rise in the sea level, like an asteroid/meteorite impact on the poles, than it can very easily have a devastating effect on the humans.

If an asteroid/meteorite hits one of the poles, than in only few hours the sea level will rise significantly, and that will cause a flash flood, where there will be not enough time for the people to evacuate themselves, and most of the population will be directly influenced by it, thus causing hundreds of millions, if not over a billion deaths.

Sveta_85 [38]

Answer:

Inhibits

Explanation:

Some mechanisms are essential for maintaining homeostasis in the human body. One of the most used mechanisms by our body is the negative feedback system. It causes a negative change from the initial change. As mentioned in the question, this often happens in the hypolamo-pituitary axis, such as when the adrenal cortex produces cortisol, this same cortisol inhibits the adenohypophysis and hypothalamus. It's also important to mention that deregulation in this process can lead to an undue chronic increase in cortisol and can lead to diseases such as anxiety disorder.

Papessa [141]

Answer: The options were missing, but the endocrine organs that secret each gland are:  

Pituitary gland: Thyroid-stimulating hormone

Pituitary gland: Adrenocorticotropic

Hypothalamus: Gonadotropic

Pituitary gland: Prolactin

Pituitary gland: Growth hormone

Thyroid gland: Thyroxine

Thyroid gland: Calcitonin

Thyroid gland: Triiodothyronine

Hypothalamus: Antidiuretic

Hypothalamus: Oxytocin

Adrenal gland: Glucocorticoids

Adrenal gland: Mineralocorticoids

Adrenal gland: Epinephrine

Pineal gland: Melatonin

Thymus gland: Thymosins

Pancreas: Insulin

Pancreas: Glucagon

Explanation:

  • The pituitary gland, also known as the hypophysis, produces the thyroid-stimulating hormone, the adrenocorticotropic, prolactin, and growth hormone. The hypophysis has two parts, the anterior one and the posterior one. The anterior one secretes these hormones thanks to the action of hormones that comes from the hypothalamus.
  • The hypothalamus, which is a gland that is in the brain, produces:

gonadotropic, antidiuretic, and oxytocin. Once produced, they are stored and secreted by hypophysis. In this case, these hormones are in the other portion of the hypophysis, the posterior part. The hormones act in the reproductive system.

  • The thyroid gland, which is in the neck, produce and secretes:

thyroxine, calcitonin, and triiodothyronine. The calcitonin controls calcium concentration, while the thyroxine and triiodothyronine impact the cells' metabolism.

  • The adrenal gland is above the kidneys. It secretes Glucocorticoids, Epinephrine, and Mineralocorticoids. The mineralocorticoids regulate the concentrations of water and salt in our body; glucocorticoids have many functions, one is fighting inflammation; lastly, epinephrine, also known as adrenaline, is released in a fight or flight reaction.
  • The pancreas is an organ and a gland. As a gland, it secretes glucagon and insulin to regulate the concentration of glucose in the blood.
  • The pineal gland is on the brain. This gland secretes melatonin, which is a hormone that helps us to sleep.
  • The thymus gland is in the chest, and it produces a hormone called thymosin. This hormone helps in the production of leucocytes, which the thymus produces.
