ABSTRACT
In this chapter the concept which allows to investigate the behavior of open (biological) systems by using the laws of unbalanced (classical) thermodinamics is examined. The second law of thermodynamics is applicable to open systems as well, provided that only in case of considering of the whole system (continuum) “open system – environment” the total entropy will always to increase. The law of temporary hierarchies allows to resolve quasi-closed thermodinamic systems in open biosystems and to investigate their development (ontogenesis) and evolution (philogenesis) by studying changes in the value of Gibbs’ specific fuctions of formation of any submolecular structure (including a population).
