Answer: in general, the physico-chemical properties of ammonia, hydrogen and ethylene arevery different. However, they can be combined into one class of so-called signal molecules ofgaseous substances, which are small molecules of gases and can be synthesized in any livingorganism or come from the outside, both forcibly and non-involuntary. At the same time, suchmolecules cause certain biochemical reactions in the body, as well as physiological changes.Thus, ammonia in high concentrations causes destruction of the liver, but at the same time it isformed in the body with the metabolism of amino acids. Hydrogen is not formed in the body ina molecular form, but participates only in the biochemical cycles of the animal organism in theform of a proton, however, recently it has been used for the prevention of cancer byadministering it orally. Ethylene is a kind of hormone in plants, accelerating the ripening offruits. Thus, answering the question "why ammonia, hydrogen and ethylene are similar," acompletely unambiguous answer can be obtained: "because they are part of the group of signal

molecules of gaseous substances."
