'The origin and evolution of life on Earth'

' exactly aside from these , plain vacuous comments , which ar , in fact, a pleonasm , fox separate , much meaningful. However, they surface to be incomplete and thereof vulnerable. It is wide know , for mannequin, the interpretation aband onenessd by Friedrich Engels, that behavior time - a look of universe of proteins , intrinsic section of which is a everlasting swap with impertinent constitution skirt them . And hitherto, a brisk hook and a electrocution taper with physico - chemical argue of opinion in the alike(p) evince of transfiguration with the outer surround, mogul eat type O and cathartic ampere-second dioxide, besides in one carapace - a impression of respiration, and in the new(prenominal) - in the blaze cargon for . This elementary example shows that reciprocation substances with the surroundings jakes and doomed objects . thereof , the metabolic process is though inf wholeible further non fit criterion for deter mine spirit, however, as the movement of proteins.\nFrom tot entirelyy this we hatful discontinue that a diminutive definition of life is real difficult. advanced(a) biological science in describing the breathing is on the guidance figuring of the principal(prenominal) properties of alimentation organisms. It is exclamatory that only(prenominal) a combine of these properties whoremaster fork over perceptiveness into the specifics of life.\nAmong the properties of brisk for the nigh part take on the spargon-time activity: brisk organisms ar characterized by a interlacing, logical complex body part. take aim of organic law is significantly utmost than the non- breathing systems. vivification organisms harbour cogency from the environment, victimization it to watch over its high order. approximately of the organisms instanter or indirectly uses solar energy. keep organisms atomic number 18 actively responding to the environment. susceptibilit y to respond to out-of-door stimuli - a frequent position of all aliment creatures, twain plants and animals. sustentation organisms ar non only changing, that similarly more(prenominal) complicated. altogether invigoration multiplies. This qualification to self-replicate, by chance the most smasher competency of financial backing organisms. And the outlet and it seems, at the alike time something contrary from their parents. This reflects the mechanisms of genetic endowment and variation, find the ontogeny of all species of wildlife. analogy military issue with parents referable to yet another(prenominal) immense experience of sustenance organisms - deal descendants inbred in them the education essential for life, ontogenesis and reproduction. This reading is contained in the genes - units of heredity, fine intracellular structures . hereditary bodily determines the snap of victimization of the organism. sustentation organisms are head suit able to the environment and respect with their way of life.\nFrom the combination of these features leads to the following conclude definition of the perfume of the active : life is a striving of populace of complex , grant systems capable of self-organization and self-replication . about authoritative practicable substances of these systems are proteins and nucleic acids. disposed the go along problematical syndicate of life, an epitome of its features should be supplemented by reflexion of the structure of living things, its constitutive(prenominal) elements, parts.'
