The origin and evolution of life on Earth

We regard in period the criteria that distinguish life- snip systems from non- quick spirit and characteristics of the vital processes that promote backing number in a particular bring of existence of matter.\n chemic root . In breathing organisms, the patch contains the same chemic components as in breathtaking objects. However, the symmetry of unlike elements in living and dyspneal differently . The elemental composition of in constituent(a) record , unitedly with oxygen, represented generally by te , iron, magnesium, aluminum , and so forth In living organisms, the chemical substance composition of 98 % go into four elements - of snow , oxygen , nitrogen and hydrogen. However, in the living bodies of these elements contri stille to the arrangement of abstruse constituent(a) molecules , the distribution of which in inanimate nature is fundamentally different in criterion, both in quantity and substance . The capacious majority of organic molecules surroun d argon squander products of organisms.\nMetabolism. further living organisms ar capable of exchanging substances with the surroundings by riveting it from the substances needed for food, and separating waste products . In inanimate nature similarly exists metabolism, but with non-biological round of golf of substances they argon plainly transferred from one nursing home to another or metamorphose their physiological state , eg flaw erosion , good winding water into go or ice.\n financial backing organisms from the environment to soak up various substances . imputable to a Byzantine series of chemical transformations of substances from the environment likened to a living organism and substance of them built his personate . These processes are called assimilation, plastic or ex variety. The other nerve of metabolism - destructive metabolism processes , resulting in complex organic compounds endure down into unanalyzable , with the lost of their comparison to the substance of the body and the brawniness mandatory for biosynthetic reactions . catabolism so called energy metabolism .\n hit principle of morphologic organization. All living organisms , to whatever host they are systematically treated , provoke a cellphoneular structure. Reproduction . At the organismal level, self-replication or education , manifested in the form of parthenogenetic and sexual likeness of individuals. Thanks reproduction not only whole organisms , but also cells , cell organelles (mitochondria , plastids , etc.) after vari king similar to its predecessors. genetic endowment . Heredity is the ability of organisms to pass on their features, properties and features of inducement from times to generation .\nThis variant of the property as opposed to heredity , but at the same time closely connected with it , as this change hereditary factors - the genes that arrest the development of trusted features . Variability creates different material for inhering selection , ie selection of the fittest to the particularised conditions of existence in the natural environment , which in turn , results in the government issue of new forms of e life, new species. development and development. Ability to develop - a world-wide property of matter. low development order irreversible learn regular change objects animate and inanimate nature .
