Аннотация:A characteristic feature of weak impacts is the non-monotonic response of living organisms and model biological systemsto monotonically decreasing impacts. The qualitative similarity of the effects caused by the different acting factors makesone think about the common cause of the observed effects, which is water. A comprehensive analysis of the actual compositionof water indicates that water under normal conditions is a multicomponent open non-equilibrium system. Nanobubblesthat are always present in water play a significant role in the properties of dilute aqueous solutions. When collapsed, theycan produce active oxygen and nitrogen species that have a strong effect on biological systems. Significant non-monotonicchanges in electrical conductivity found in a series of sequentially diluted solutions subjected to vigorous shaking after eachdilution convincingly demonstrate the presence of chemical changes in the composition of aqueous solutions explained bymechanochemical processes. Similar changes were observed in water samples prepared in the same manner with vigorousshaking and dilution without the addition of any chemical compounds. The long-term evolution of the conductivity of suchsolutions depends on the chemical structure of the solutes.
