Describe what hormones are and what they do

Hey hope this helps. So starting off with a few things that cause hormones.

The Endocrine System , So The best way to answer the question "what are hormones?"  is to take a look at some of the major hormonal systems in the body. Hormones are created by glands, which are part of the endocrine system. The main hormone-producing glands I've listed below

Hypothalamus: The hypothalamus is responsible for body temperature, hunger, moods and the release of hormones from other glands; and also controls thirst, sleep and sex drive.

Parathyroid: This gland controls the amount of calcium in the body.  

Thymus: This gland plays a role in the function of the adaptive immune system and the maturity of the thymus, and produces T-cells.  

Pancreas: This gland produces the insulin that helps control blood sugar levels.  

Thyroid: The thyroid produces hormones associated with calorie burning and heart rate.  

Adrenal: Adrenal glands produce the hormones that control sex drive and cortisol, the stress hormone.  

Pituitary: Considered the "master control gland," the pituitary gland controls other glands and makes the hormones that trigger growth.  

Pineal: Also called the thalamus, this gland produces serotonin derivatives of melatonin, which affects sleep.  

Ovaries: Only in women, the ovaries secrete estrogen, testosterone and progesterone, the female sex hormones.

Oh and by the way the person below me copied and pasted her answer here's proof. I posted a screenshot of her answer.

Just saying.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

the answer would be knowledge about cars!
