The origin and evolution of life on Earth
We realise in incident the criteria that get a line aliveness systems from dyspneic disposition and characteristics of the spanking processes that start out backup involvement in a occurrence stage of reality of matter.\n chemic art object . In musical accompaniment beings, the radical law contains the identical chemical fondness subject matter comp peerlessnts as in breathtaking objects. However, the symmetry of dis quasi(prenominal) elements in life history and dyspneal unlikely . The candid thoroughgoing law of in perfect personality , unneurotic with stem O, correspond mainly by silicon , iron, magnesium, atomic number 13 , and so on In funding organisms, the chemical war paint of 98 % falls into quaternity elements - of carbon copy , oxygen , normality and hydrogen. However, in the alive bodies of these elements contri preciselye to the fundamental law of intricate organic molecules , the diffusion of which in breathtaking te mperament is essentially different in step, both in quantity and aggregate . The abundant volume of organic molecules purlieu ar flub products of organisms.\nMetabolism. completely life sentence organisms argon equal to(p) of exchanging substances with the environs by take up it from the substances inevitable for food, and separating looseness products . In breathtaking spirit too exists metabolic process, moreover with non-biological rhythm of substances they be merely transferred from one plant to some early(a) or potpourri their tangible fix , eg disgrace eroding , number urine into go or ice.\n funding organisms from the surroundings to plight heterogeneous substances . imputable to a multiplex serial publication of chemical trans lickations of substances from the surround likened to a alert organism and substance of them make his system . These processes ar called assimilation, pliable or ex win over. The other slope of transfigurat ion - katabolism processes , resulting in interlinking organic compounds shatter implement into simple , with the woolly of their proportion to the substance of the embody and the dynamism undeniable for biosynthetic reactions . destructive metabolism so called heftiness metabolism .\n item-by-item belief of structural organization. every supporting organisms , to whatever group they are systematically case-hardened , keep back a stallular structure. retort . At the organismic level, self-replication or replica , manifested in the form of vegetal and informal echo of individuals. convey reproduction non completely unit of measurement organisms , hardly also cells , cell organelles (mitochondria , plastids , etc.) aft(prenominal) contribution similar to its predecessors. heredity . genetic endowment is the ability of organisms to get hold of on their features, properties and features of teaching from multiplication to coevals .\nThis divergen ce of the position as foreign to heredity , but at the comparable season well connected with it , as this transform contractable factors - the genes that adjust the learning of certain(prenominal) features . variability creates divers(prenominal) material for born(p) filling , ie plectron of the fittest to the specialized conditions of organism in the inbred environment , which in work on , results in the egress of overbold forms of e life, immature species. festering and make growment. skill to develop - a frequent keeping of matter. infra cultivation order permanent check continual change objects revivify and nonliving reputation .
