By definition, if the DNA of a cell undergoes a spontaneous mutation, is not due to <u>exposure to radiation.</u>
<u></u>
Spontaneous mutations are derived from various sources, which include mistakes made all through the replication of undamaged template DNA, mutagenic nucleotide substrates, and endogenous DNA lesions.
Spontaneous mutation, also referred to as background mutation can be defined as genetic modifications that arise inside the absence of mutagens and haven't any recognized reason.
It is able to result from sports of a normal cellular, including mistakes or errors during DNA replication.

An old adage once say and i quote "women fall in love with people; men fall in love with genitals." Hence, Body-centered sex is common in MEN
The Answer:
Choice C: mRNAs that are expressed from a specific gene.
Answer:
The glands of the endocrine system and the hormones they release affect almost every cell, organ, and function of our bodies. The pituitary also secretes hormones that signal the reproductive organs to make hormones. The pituitary gland also. In boys the male gonads, or testes (TES-teez), are in the scrotum.
Explanation:
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.
