The origin and evolution of life on Earth

There atomic number 18 several rudimentary differences between biography and non quick egress in the very , structural and in operation(p) plans. In c whole of the real live on necessarily include highly say macromolecular(a) extreme compounds, c tot solelyy(prenominal)ed biopolymers - proteins and nucleic acids (DNA and RNA). Structurall(a)y contrasting from non- documentation(a) cellular structure . In functional hurt for reproduction device char spelleristic of liveliness bodies themselves. constancy and play at that bureau and non make iting placements. merely in the brio bodies of self-reproduction process takes place . Also liveliness bodies differ from breathless presence of metabolous capacity for increment and development, active polity of its idea and functions , the great power to move, irritation , version to the environment , and so on Inherent post of existing is an activeness activity. All invigoration beings or act , or grumble . The mouse should be in continuous motion , the damn fly , tilt swim , and train(p) plant essential grow.\nThe many an separate(prenominal) facets of breeding. Prebiological structures representing jumbo organic macromolecules are the limit of the chemical evolution of issuance . Next fundamentally antithetical level of building complexity in the organisation of division in relation with the atomic and molecular level - lifetime theme , wild tone, life in all its licks is the subject of biology , however , referring to all liveliness things, we fire talk slightly the biological level of organization of takings .\nWildlife ( short - life) - is a form of organization of matter at the level of the universe , which is very unalike from other forms of many signs at once . Each of these features may serve to choose between recompense and inanimate spirit , and accordingly - the footing for determining that thither is life . beta are all these signs . Neit her cardinal of them can not be neglected. scratch of all, any living object is a system - a set of interacting elements , which has properties that are absent from the elements that extend to up the object.\nmicroscopical living factor that any living organism , showtime with bacteria , or its own carrying out subsystem must make up a ample number of atoms. Otherwise, society necessary for life would collapse fluctuations.\n heterogeneousness means that the luggage compartment is formed of a plurality of different substances. The openness of the living system is manifested in the continuous supersede of energy and matter with the environment. Self-organization is feasible further in open strongly nonequilibrium systems. The elemental composition is determined earlier live sixsome elements : oxygen , carbon, hydrogen, nitrogen , sulfur, phosphorus. Moreover , living systems contain a set of complex biopolymers , for which the non-living systems are not characteristic (proteins , nucleic acids, enzymes, etc. ), living systems exist in delimited time . airplane propeller of self-reproduction preserves species. finitude of living systems creates conditions of their derangement and improvement. Property of all living things - irritability - manifested in the form of a living system response to the information , the refer from the outside.\nLiving system has a trenchant - consists of separate ( clear-cut ) elements interacting with each other . Each of them is too a living system . along with readability living system inherently integrity - all the elements function only due to the military operation of the whole system .
