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.

AVprozaik [17]

The phenotypes of snapdragons of F1 generation had pink flowers only.

Explanation:

The crossing of snapdragon with red flowers and white flowers as well led to the production of F1 offspring of hybrid quality having pink flowers only. This F1 phenotype under goes pollination and results in F2 phenotype with a ratio of 1 red, 1 white and 2 pink flower.

This is incomplete dominance as the phenotypes of parental plant, as in the white and red flowered plant reappear in the F2 generation.
