Ndeipi TOUR symmetry? Chii mhuka dzine TOUR symmetry?

Chete dzimwe mhuka hariwanikwi yedu nyika! Vamwe rova saizi dzavo, dzimwe tsika inoshamisa uye nzira youpenyu, vamwe anosiyana incredible ruvara.

Asi zvikuru unoshamisa muviri mamiriro vachiri gungwa uye yomugungwa vagere. muviri wavo chimiro kunogona kujairika nokuti ane symmetry uncharacteristic mhuka yenyika. Izvi TOUR symmetry.

Mhando symmetry kwemhuka

mhuka dzose pamusoro mhando symmetry muviri zvinogona mapoka mapoka mana:

• Mhuka chete bilateral symmetry (dvustoronnesimmetrichnye). boka iri zvinosanganisira marudzi dzakawanda nemhuka dziri munyika, uye rinokosha egungwa. The chikuru chepfungwa - ndiyo nzvimbo dzomuviri nhengo symmetrically panyaya imwe kuitwa kuburikidza ndege. Somuenzaniso, kuruboshwe uye zasi muviri, asi shure uye mberi.
• TOUR symmetry muviri (TOUR symmetry). Hunhu mhuka zvomumvura uye zhinji yakadzika. The chikuru chepfungwa - maumbirwo muviri nenzira kuti kuburikidza dzayo nechepakati akabatana anogona kupedza mashomanana zvekufungidzira mitsetse pamusoro izvo nhengo dzomuviri vanosarudzirwa symmetrically. Somuenzaniso, namatanda Starfish.
• Mhuka chete asymmetric chimiro muviri. Kana symmetry hakusi chaiwo zvachose, chimiro ari dzichichinja zvichienderana zvakatipoteredza ezvinhu kana kubva kwebasa mhuka. Muenzaniso - Amoeba Proteus.
• Kushaya symmetry zvachose. Utachiona ava sechipanji. Vari kuda nzira youpenyu, anogona kukura pamusoro substrate panguva Mavhoriyamu dzakasiyana uye asina mumwe symmetry marongerwo muviri.

Nerimwe boka zvipenyu dziri atakatora oga Vamwe vanobatsirwa ayo mamiriro. Somuenzaniso, mhuka bilateral anogona kufamba vakasununguka zvakanaka, akatendeuka padivi. Mhuka chete TOUR symmetry kukwanisa kubata akasiyana pamakona zvakatapwa. Asymmetric zvinenge zvakakunakira nzira kutama uye zvinoenderana dzezvakatipoteredza ezvinhu.

TOUR symmetry: nayo

The chikuru chinoratidza nemhuka TOUR symmetry, ndiwo yavo kujairika muviri chimiro. Ndivo kazhinji ainge akamonererwa kuita raundi, cylindrical kana chimiro nyeredzi kana nyika.

Kuburikidza muviri zvipenyu zvinogona kuitwa zvakawanda namasanhu noruremekedzo kune mumwe nomumwe wavo pane vaviri zvachose zvakafanana, ichibata sezvikamu. Urongwa hwakadaro anovapa mukana kuti nhamba zvakanakira:

1. Vakasununguka kuenda chero divi, kudzora kunhivi dzose dzakanga dzakamupoteredza.
2. Hunting kunova makuru hukuru, sezvo kugadzirwa Runonzwika kumativi muviri wose.
3. The kujairika Maumbirwe muviri runoita kuti ajairane yakapoteredza landscape, ndidire mariri uye kuva asingaoneki.

TOUR symmetry muviri - mumwe mukuru zvishandiso kuti makirasi chaiyo mhuka munyanza zvipenyu nezvakazvipoteredza munharaunda.

Zvinoitwa TOUR symmetry muviri

Nhoroondo panowanikwa mano zvakadai, dzakadai TOUR symmetry muviri, anotaura midzi yawo kuti madzitateguru mhuka Coelenterata mhando. Vakanga zvachose ndakagara, mira upenyu uye dzakanga dzakabatanidzwa substrate. Vaizova kubatsirwa kubva symmetry kwakadaro, uye ivo akamupa kutanga.

The chokuti zvino vazhinji vachishingaira kushambira nemhuka vachiri vane TOUR symmetry, hurukuro pamusoro neredutsirovannosti yake mukufamba shanduka. Zvisinei, chinangwa chacho zvakananga, chikamu ichi hachisisiri achiita.

Zvichireva TOUR symmetry

Chinangwa charo chikuru mune yemadzitateguru siyana, uyewo ano, achitungamirira yakasimbiswa upenyu - kupa kudzivirirwa yokurwiswa pazvikara uye nezvavakatapa chikafu.

Pashure pezvose, nemhuka TOUR symmetry, vakanga vasingakwanisi kuzvidzivirira, kutiza chikara, uye havana kugona kuvanza. Naizvozvo, chete nzira yakanga kunzwa kudzivirirwa rava kusvika panjodzi ipi kurutivi muviri kuti sei uye anodzivirira nzira.

Uyezve, kuti awane chouviri yavo when're munhu ndakagara mararamiro, ndizvo zvakaoma. A TOUR symmetry unokubvumira abate kuchangotanga zvinyorwa zvokudya akapoteredza muviri wose uye nokukurumidza kuipindura.

Saka TOUR symmetry muviri chinopa zvikuru kudzivirira zvenhengo uye zvokudya mhuka nayo.

mienzaniso mhuka

Kune mienzaniso yakawanda nemhuka TOUR symmetry. kusiyana kwavo hombe zvipenyu uye kusanganiswa yakashongedzwa gungwa uye gungwa nechepasi uye mvura mbiru, anobvumira munhu kuyemura pebhanhire hunhu uye kunaka pasi pemvura nyika.

Chii mhuka dzine TOUR symmetry? Somuenzaniso, yakadai se:

• gungwa urchins;
• muramba;
• gungwa wemagaka;
• pfava;
• zmeehvostki;
• hydra;
• Starfish;
• Ctenophora;
• wakaiswa polyps;
• mamwe marudzi sechipanji.

Ndivo mienzaniso yakawanda zvinowanzovapo TOUR symmetry muviri kwemhuka. Kune dzimwe mhuka, vaduku kuzivikanwa, uye, zvichida, zvose haisati akazaruka, ayo kuburikidza zvakadai zviri remitemo inozivikanwa.

coelenterates

Izvi mhando dzemhuka rinosanganisira makirasi matatu huru, vakawanda aizoonekawo anomiririrwa chokwadi kuti vari mhuka dzose TOUR symmetry. The upenyu zvinogara hunodzorwa chero vakasununguka-zvinoyangarara medusa pachikuva, kana dariro ane polyp vasiyana substrate. mumwe Hole, mashandiro dzaiita zvokutaurwa, nokunobuda netsvina uye pabonde. Kudzivirira kushandiswa muchetura masero anopedza.

1. Hydroids. The chikuru dzinomiririra: ari hydra, hydrants. Vari kurerekera nemararamiro akaita coelenterates zvose, vaviri akaturikidzana mu sechivako pachitunha; ectoderm uye endoderm. Chinoumba rukoko chinhu gelatinous rizere mvura fuma sezvamunoita - mesogloea. The muviri chimiro zvinokonzerwa mukombe serin'i. The chikuru muupenyu iri kupedzerwa mubasa pavaipfuura polyp.
2. Muramba (scyphoids). Vamiririri Key - zvose zvamarudzi muramba. chechienzi muviri chimiro, muchimiro bhero kana ainge akamonererwa. Vanodawo hunyambiri-rukoko mhuka pamwe TOUR symmetry. The chikuru muupenyu hwapera mu padariro munhu vakasununguka chinofamba muramba.
3. Coral (polyps). The chikuru vamiririri: anemones, korari. The huru Pakanzi - a yaitonga mararamiro. Vazhinji Coral kumboongororwa vanoumba yose zvayo Mugari nyuchi. Single siyana uyewo dzinoitika, izvi ndiwo marudzi akasiyana gungwa anemones. Stage muramba kazhinji kacho asina kwese mhuka idzi, chete pechikuva polyps.

In zvose pane anenge 9000 mhando nhengo kwakadai mhuka.

echinoderms

Kunyange dzimwe mhuka dzine TOUR symmetry? Chokwadi, akakurumbira uye akanaka kwazvo, kujairika uye rakajeka echinoderms. Izvi mhando ine vanenge 7000 mhando zvinoshamisa zvomugungwa izvi. Pane zvidzidzo zvikuru shanu:

• Sea wemagaka - akafanana nehonye, asi vachiri vane TOUR symmetry. Nemavara, ivo havadi kufamba nemuGungwa.
• nyeredzi pfava - nowenyika nyeredzi mugungwa, asi kuva yepamusoro mufambo uye urombo coloring - chena, mukaka uye tsvukuruka mavara.
• Sea urchins - vanogona kuva akarurama tsono zvokunze marangwanda, kana varege kuva tsono. The muviri chimiro ndiyo inenge nguva dzose pedyo idenderedzwa.
• Starfish - shanu, vasere, kana gumi-mhuka ine simba TOUR symmetry. Very zvakanaka kupendwa, mararamiro ndiwo ndakagara, zvinokambaira pamwe pasi.
• Crinoids - agere mhuka dzakanaka, vane TOUR Maumbirwe ruva. Inogona kuparadzaniswa kubva substrate uye kutamira kunzvimbo akapfuma chikafu.

Lifestyle kunogona kuva chinjwa vakakoshesa saka (gungwa seruva). Mutumbi maviri layer nemumuromo mhango uye anoita mashandiro neshure. Exoskeleton madota simba zvakakwana, zvakaisvonaka yakashongedzwa mavara mapatani.

The mazana emhuka idzi bilateral symmetry muviri, uye chete vakuru doraschivat nemwaranzi kuti TOUR.

Ctenophora

Kazhinji diki kwemavara mhuka (20 cm) umo zvachose chena, translucent muviri, akashongedzwa mitsara mizinga. Izvi mhando dzemhuka ichaongororwa imwe yenzvimbo yekare. Muzinga mondo zvikara Tidzidze crustaceans, hove diki uye kunyange mumwe. Very ndichibvunza rutoto.

Nemamiriro muviri pane wechitatu embryo shizha. The muromo kuvhura pamusoro yokumusoro chikamu muviri, zvichiita kuti kuyangarara vakananga pachena mararamiro. The mhando Zvinonyanyozivikanwa:

• Beroe;
• platiktenidy;
• gastrodes;
• Venus nebhanhire;
• bolinopsis;
• tyalfiella.

TOUR symmetry yavo, uyewo TOUR symmetry vamwe coelenterates mhuka havaratidzi akaratidza. muviri yakaita chinhu denderedzwa kana hombodo.

kungotaurawo

Saka TOUR symmetry muviri - ndiwo anozviita mhuka hwemvura, kutungamirira munhu ndakagara mararamiro, kana kuda pavanatenzi vavo uye inopa mikana iri kuvhimwa chayabata uye kunzvenga nezvikara.
