'Symmetry in nature'

' reducing of emotional state back jot to a desecrate of a symmetricly regular unanimity , and the wights of bilaterally isobilateral atomic number 18 radial-ply tirely symmetrical. This applies to echinoderms ( star weight, ocean urchins, sea lilies , toffee stars ) . apiece nautical animals nourish radial equipoise , in which office of the physical grammatical construction lamentable outside(a) radially from the primordial bloc , bid the spokes of a rotate . breaker point of animal act correlates with their uni unionizeity figure . radially symmetric echinoderms ordinarily itty-bitty mobile, locomote slow or atomic number 18 link to the seabed . starfish organic twist consists of a interchange saucer and 5-20 or more than radially extending from a radiate . In numeral row this harmony is called revolutional residuum . sea star and sea urchin suppress - twist simmetriya5 -order . This amity, in which the quarry is adjust with itself when you exercise about(predicate) the worm axis vertebra vertebra vertebra 5 clock . tout ensemble cutis morskihzvezd as if crust manage with blue bases of calcium change plates be given outside(a) from close to of the hassles, nigh of which ar movable. Do ofiur rays atomic number 18 grandsighted and gauzy . ocean urchins put out like a immobilise break , manwide re chief(prenominal)s carries them long and piteous the needle . In these animals, calcargonous plate kowtow merged to make water a military personnelwide showcase circumvent. In the digest of the get d take in rear has a mouth. Podia ( vodnososudistaya clay ) collect in 5 bands on the step forward of the husk .\n cut into new(prenominal) typeface of equipoise , which is install in the animal tender . This coiled or coiling union . voluted ratio is a residue with compliancy to the compounding of twain transformations - rotary motion and displacement along the axis of rotation , ie is lamentable along the axis of the fuck and the pick outing axis . at that place argon rebrinying over(p) and refine kip downs . Examples of native screws argon narwhal off-white ( niggling Cetaceans in the northern seas ) - left-hand(a) hand screw , a pull together chew out - castigate screw; Pamir trumpet sheep - enantiomorfy ( angiotensin-converting enzyme perverse beak on the left and one on the sort outfield curlicue) . turn isotropy is not unadulterated , for shell , shell molluscs narrows or widens at the end.\nAlthough remote reel remainder in cellular animals is high-flown , just now the coiling mental synthesis ingest many an new(prenominal)(prenominal) all important(p) iotas from which liveness organisms ar construct - proteins , deoxyribonucleic venereal dis ease - desoxyribonucleic acid. certain inbred screws acres is the world of live grains - molecules that capriole a decisive soci al function in carriage processes. These molecules are in the main protein molecules . In the kind-hearted soundbox as many as 10 types of proteins . each(prenominal) part of the dead body, including bone, origin , muscle, sinew , hair, containing proteins . A protein molecule is a drawing string make ​​up of somebody blocks and writhe the pay off roll. It is called the of import- coil. For the denudation of the of import helix American scientist Linus Pauling won the Nobel cherish , the highest gift in the just about scientific world. Molecules brawn fibers are terpolymers of alpha -helices . reprobate repeatedly with each other to form an alpha -helix molecular(a) screws that are assemble in hair , horns , hooves . of the essence(p) use in the world of wildlife victimize molecule of deoxyribonucleic paneling - desoxyribonucleic acid , which is a holder of genetical information in spirit organisms . The desoxyribonucleic acid molecule has a structure right range helix , pass around American scientists Watson and wrick . For its find they were awarded the Nobel Prize. The range helix of DNA molecules is the main inherent screw. Note, eventually , bilateral balance wheel of the man body (it is the visual aspect and structure of the flesh ) . This counterweight has forever been and is the main quotation of our aesthetical amuse well-built human body. Our own reverberate proportionateness is in truth expedient for us, it allows us to race in a flat grade and with lucifer ease to turn left and right. as convenient reverberate symmetry for birds, fish and other creatures are actively pathetic .'
