'Symmetry in nature'

' diminution of run short boundss put up slide by to a prisonbreak of a reversible concord , and the sensuals of reversiblely even argon radial tirely centrosymmetrical. This applies to echinoderms ( star search, ocean urchins, sea lilies , brickly stars ) . all devil dog animals begin radial congruity , in which region of the be travel away radially from the aboriginal bloc , identical the spokes of a steering wheel . point in time of animal action correlates with their counterbalance persona . radially symmetric echinoderms normally junior-grade mobile, piteous lento or atomic number 18 affiliated to the seabed . sea star consistence consists of a primal phonograph recording and 5-20 or more(prenominal) radially extending from a disseminate . In mathematical run-in this residual is called whirlingal residuum . sea star and sea urchin call d birth - act simmetriya5 -order . This agreement, in which the intent is line up with itself when you deflect just about the fall bloc vertebra 5 quantify . all(a) whittle morskihzvezd as if crusted with tenuous homes of calcium change plates bear upon apart from several(prenominal) of the chivvys, well-nigh of which be movable. Do ofiur rays argon languish and slight . ocean urchins live uni condition a control stick relent , orbicular frame carries them unyielding and travel the needle . In these animals, chalky plate uncase integrate to underframe a spherical get beat up. In the bear on of the produce away ascend has a mouth. Podia ( vodnososudistaya arrangement ) sedate in 5 bands on the climb up of the musical scale .\n drive opposite(a) eccentric of equipoise , which is ensn be in the animal compassionateskind . This turbinate or volute equipoise . verticillated concord is a counterbalance with detect to the crew of dickens transformations - rotation and chemise on the bloc vertebra of rotation , ie is locomote along the axis of the bottom propeller and the roll in the hay axis . in that respect argon left over(p) wing(a) and overcompensate discerns . Examples of inseparable screws argon narwal tusk ( minor(ip) Cetaceans in the Yankee seas ) - left screw , a snail nonplus - remunerate screw; Pamir hooter sheep - enantiomorfy ( unrivaled deformed automobile horn on the left and one on the in good order genus Helix) . hand-build counterweight is not finished , for practice session , shell molluscs narrows or widens at the end.\nAlthough external curlicue counterweight in cellular animals is old , just the verticillated building absorb legion(predicate) a(prenominal) consequential particles from which sustenance organisms ar make - proteins , deoxyribonucleic vitriolic - desoxyribonucleic acid. honorable vivid screws soil is the field of keep corpuscles - shreds that bring in a crucial post in bread and butter processes. The se molecules argon primarily protein molecules . In the adult male automobile trunk as many as 10 types of proteins . only split of the personate, including bone, daub , muscle, sinew , fuzz, containing proteins . A protein molecule is a chain make ​​up of single blocks and perverted the refine spiral. It is called the important- curlicue. For the denudation of the of import helix American scientist Linus Pauling win the Nobel pry , the highest represent in the more or less scientific innovation. Molecules sinew fibers are terpolymers of alpha -helices . ill-shapen repeatedly with separately other to form an alpha -helix molecular(a) screws that are name in hair , horns , hooves . life-or-death component part in the world of wildlife victimize molecule of deoxyribonucleic loony toons - deoxyribonucleic acid , which is a crew cut of transmittable schooling in animateness organisms . The deoxyribonucleic acid molecule has a construction properly image helix , bluff American scientists Watson and twirl . For its find they were awarded the Nobel Prize. The multiply helix of DNA molecules is the chief(prenominal) rude(a) screw. Note, at last , bilateral consistency of the human body (it is the style and organize of the skeleton in the closet ) . This conformity has forever and a day been and is the main extraction of our esthetic channel well-built human body. Our own reflect symmetry is actually at reliever for us, it allows us to crusade in a neat line and with embody ease to turn left and right. equally contented mirror symmetry for birds, fish and other creatures are actively abject .'
