They proposed the term to describe chemical signals from conspecifics that elicit.
hormones
When sugar is digested in an animal, ATP (Adinosine Tri Phosphate) is produced which is a chemical form of energy.
a neurotransmitter called acetylcholine (ACh) is produced between nerve cells. This neurotransmitter carries the signal (in chemical form) at the synaptic junction.
A pheromone.
The chemical signal carried through the blood is primarily hormones. Hormones are produced by glands in the body and travel through the bloodstream to target specific cells or organs to regulate various physiological functions.
Cadaverine is a foul-smelling chemical compound produced by protein hydrolysis during putrefaction of animal tissue.
Animals can emit chemical odor signals called pheromones, which play a role in communication and behavior. Pheromones can convey information about the animal's identity, reproductive status, and territory. Different species release specific pheromones to attract mates, signal danger, or establish social hierarchies.
Pheromones are chemicals (hormones) that are secreted by one animal, and are detected by another animal via special chemoreceptors, and produce detectable changes in behavior via the connection of the chemoreceptors and the brain. Therefore, pheromones acts a means of transferring a behavioral signal (or trigger) from one animal to another.
Depends on the animal, but yes, it could, if you were allergic to that animal, or if the animal's skin produced a certain chemical. We can severely hurt butterflies if we touch them with our fingers, as our oils are bad for their wings. So yes.
products are produced after a chemical reaction.
ptalonomy is a chemical compound produced by bacteria
