What are the chemicals signals transmitted through water or ran?

Chemicals signals that can be transmitted through water or air include:

- Pheromones: Chemical signals released by an animal that affect the behavior or physiology of other animals of the same species. For example, many insects use pheromones to attract mates or warn of danger, and some mammals use them to mark their territory.

- Allelochemicals: Chemical signals released by one organism that affect the behavior or physiology of another organism of a different species. For example, some plants release chemicals that inhibit the growth of nearby plants, while others release chemicals that attract pollinators.

- Hormones: Chemical messengers that are produced and secreted by endocrine glands and transported by the bloodstream to target cells or tissues. Hormones regulate many different bodily functions, such as growth, reproduction, and metabolism.

- Neurotransmitters: Chemical messengers that are released by neurons (nerve cells) to transmit signals to other neurons or to muscle or gland cells. Neurotransmitters are responsible for a variety of functions, including communication between different parts of the brain, control of movement, and regulation of mood.
