The structural and functional unit of the body level is the body, and the unit of the cellular standard of living is the cell.
At the organismic level, the following phenomena occur: reproduction, the functioning of the body as a whole, ontogenesis, etc.
The structural elements of the cellular level system are various complexes of molecules of chemical compounds and all structural parts of the cell – the surface apparatus, nucleus and cytoplasm with their organoids. The interaction between them provides unity, the integrity of the cell in the manifestation of its properties as a living system in relations with the environment.
At the cellular level, the following processes occur: metabolism (metabolism); absorption and, therefore, the inclusion of various chemical elements of the Earth in the contents of the living; transmission of legacy vein information from cell to cell; accumulation of changes in the genetic apparatus as a result of interaction with the environment; response to irritation when interacting with the environment.
