When The Temperature In A Thermostat Case Will

When the temperature in a thermostat case will exceed set, that is necessary, a mercury column in the relay, rising from heating, will switch off an energy source. Thus, will work a feedback mechanism. On the contrary, as soon as the system starts to be cooled, the mercury column decreases also it again includes a source of a power food. Some systems which support a constancy of the internal environment, are strictly regulated according to mechanisms of negative communication. These systems provide performance of the law of a constancy of the internal environment of an organism. But if in system all is counterbalanced, all is strictly commensurated, how there can be that additional energy and that additional "a building material" which should be spent for development and organism growth? Having asked this question, it is easy to come to a conclusion that the constancy of the internal environment, in essence, forbids organism development. In what image this contradiction between stability - a life basis, and development - a life source is authorised? To consideration of it we now also will pass.

But What Image Provides Capacity Strengthening The System

But what image provides capacity strengthening the system protected by the law of a constancy of the internal environment? Studying of this question leads to a conclusion that the law of a deviation of a homeostasis extends not on all adjustable functions of a live organism, and only on three of them. But these three functions supervise three basic properties of a live organism. The property distinguishing live system from lifeless, is ability of live system to reproduction, the adaptation (adaptation) and regulation of a stream of energy (or a metabolism). The Metabolism providing maintenance of power processes, is the main thing from three basic properties of live system. Finally the live system is the power car consuming fuel - food for maintenance of the structure and activity. At the same time activity of live system is substantially subordinated to adaptation requirements - to the adaptation to varying conditions of the external and internal environment of an organism. The above ability to adaptation, the above viability of system.
