this world does disappear and appear (the conservation law). The whole world consists of protons, neutrons and electrons, but we see various objects which differ in color, consistence, taste, form, molecular and atomic composition, etc. It means that in the course of specific interaction of protons, neutrons and electrons certain inter-elementary connections are established. At that, some of their properties would be neutralized, while others conserved or even amplified in such a manner that the whole of diversity of our world stems from it. The goal of any system is the fulfillment of the preset (defined) condition, achievement of the preset result of action (goal/objective). If the preset result of action came out incidentally, then the next moment it might not be achieved and the designated/preset result would disappear. But if for some reason there is a need in the result of action being always exactly identical to this one and not to any other (goal-setting), it is necessary that the group of interacting elements retain this new result of action. To this end the given group of elements should continually seek to retain the designated/preset condition (implementation of goal/objective). p> Simple systemic functional unit (SFU). The system may consist of any quantity of functional elements/executive component, provided that each of the latter can participate (contribute to) the achievement of the goal/objective and the quantity of such components is sufficient enough for realization of this goal. The minimal system is such group of "k" elements which, in case of removal of at least one of the elements from its structure, loses the quality inherent in this group of elements, but not present in any of the given "k" elements. Such group of elements is a simple systemic functional unit (simple, not composite SFU), the minimal elementary system having some property (ability to make action) which is not present in any of its separate elements. Any SFU reacts to external influence under the "all-or-none" law. This law is resulting from the definition of simple SFU (removal of any of its elements would terminate its function as a system) and discrecity of its structure. Any of its elements may either be or not be a part of simple SFU. And since simple SFU by definition consists of finite and minimal set of function elements and all of them should be within the SFU structure and be functional (operational), termination of functioning of any of these elements would terminate the function of the entire SFU as a system. Regardless of the force of external influence, but given the condition of its being in excess of a certain threshold, the result of its performance will be maximal, ("all"). If there is no external influence, the SFU would nowise prove out (would not react, "none"). Simple SFU, despite its name, may be arbitrary complex - from elementary minimal SFU to maximal complex ones. The molecule of any substance consists of sever...
