Science

Not a single process in the world is possible without the intervention of chemical compounds, which, reacting with each other, create the basis for favorable conditions. All elements and substances in chemistry are classified according to the structure and functions they perform. The main ones are acids and bases. When they react with each other, soluble and insoluble s alts are formed. Last modified: 2025-01-23 12:01

The genetic code, expressed in codons, is a system for encoding information about the structure of proteins, inherent in all living organisms on the planet. Its decoding took a decade, but the fact that it exists, science understood for almost a century. Universality, specificity, unidirectionality, and especially the degeneracy of the genetic code are of great biological importance. Last modified: 2025-01-23 12:01

The scientific theory of biogeocenosis was created by the Russian scientist V. Sukachev. It gives an exhaustive description of natural complexes, and also studies the diverse types of interactions between parts of the ecosystem: plants, animals, microorganisms. Particularly serious studies of the forms of biotic relationships were carried out by another Russian scientist, V. Beklemishev, who singled out four types of them. It should be noted that in ecology, topical connections are one of the most common types of. Last modified: 2025-01-23 12:01
