" hormone is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behavior. hormones have diverse chemical structures, mainly of 3 classes: eicosanoids, steroids, and amino acid derivatives." Hope this helps-
Explanation:
Hormones are the chemical messengers that coordinate complex processes like fertility, growth and metabolism by traveling throughout the body. Hormones are secreted directly into the blood by the glands, in reaction to the signals received from the brain. All cells in the bloodstream are exposed to the hormones,but only a hormone's target cell reacts, which have receptors for that hormone. Hormone disrupting chemicals can act at any point along this pathway. Some of them are mimic, which sends a false signal by binding the receptor that is not commanded by the brain.
