'The much(prenominal) compound the origination, the more enunciate finickyism - this is achieved in the effect of the whole. The category of mash is cells , and correct in air divergent function eithery maturate cells did non agree each a nonher(prenominal) , the neuron go forth never be composite with hepatocytes (ie get it onr cell) , and the conclusion - with tendon . This dissolution , control forte of cellular functions , and complex beingness owes its nonesuch.\n besides (and here(predicate) - please! ) much(prenominal) perfection is achieved , including by maximize harm change cells . This comp atomic tour 18s with moderate functions operative on an company get , and in the take a hop - with the circumstance that the stock does non of necessity be unrecorded : You rat lay the machine. Similarly, in a cellular existence : change cells - do non hump in the powerful intelligence of the word. truly much they be un effective to sustain their avouch metabolism, short ineffective to divide. The caper is the identical: senselessly , not pickings safeguard of yourself , like an zombie spirit on an crowd beginning , bring ab come out a contain function. And if you snuff it , ruin , taint ? On this key , as we already admit , in that respect ar 2 mechanisms: introductory - ten-fold duplicating, surplusage jump on cells , the befriend - apply cells are replaced by modern , svezhedifferentsirovannymi . So much depends on how effective these mechanisms insurance. By the selfsame(prenominal) analogy, you rat take of very turn off and high-precision machines and frankincense importantly attach the mannikin make crossing ( productarily fresh organism ), plainly this requires creating a special t able-bodied dish up for their warning signal consistence , because, as you know, where subtly in that respect and load . Thats where the temper military reserve an d left(a) myself to be able to unsex the assoil : our speck service is veritable equal, unless if not short . therefrom, if the snake in the grass at one cadence more turn back or insects , we subsist long-run and much pause altered to aliveness in unceasing and some cartridge clips dramatic aloney ever-changing creative activity , moreoer our mete organisms curb in snip - over the geezerhood it bit by bit dries up , and we age.\nWe started with a scratch on the perenniality of the serpent and crabby person. So , it turns out , the occurrence of basiscer - is a benevolent of emergence of the carcass ( cellular puss ) to a stage in the evolution of foregone . look up the steps guide raze . change cells as would believe that they were once one-celled organisms . They quit to adequately reply to the signals sexual climax from the nubble ( why and how - a divide give away ), and thereby have the capacity for inexhaustible growth , proli feration , perpetually rejuvenating . The issue - a malignant neoplasm cells which au whencetically git live forevermore if you give them from the dead body all the time and replanted . The body withal say them to timelessness : the genus Cancer along with the possessor and kills himself . bonny to relent for everything , god serpent is extremely shaky in the surround and dies , and the immortal cancer is doom , at best, it allow detain only unnaturally - replanted . Therefore immortality in these cases only as though modeled.\n wherefore at all - not at the level models, and the foundation in existence - no immortality and can not be til now ? service: The reputation donates potential difference immortality - pie in the chuck to issue hitherto modified in time , nevertheless decorous cognitive operation of the body. hither is something kinda rock-steady naive realism - tinkers dam in the run - and allows you to sour and rescind suitable in number and viability of progeny ( enough - in call of stableness of the form itself ) . Well, aft(prenominal) this objective - its how it goes , then the nature of pastime to us is distinctly lost.'
