Fish and Frog: ezifanayo nezahlukileyo

More on izifundo biology intetho utitshala malunga ezahlukeneyo zezilwanyana. Phakathi kwabo - ezi chordates yokuqala kunye ezinomqolo abemi umhlaba wethu. Ezi ziquka iintlanzi eziphila. Kwi izinto ezifanayo nezahlukileyo phakathi intlanzi kunye isele ufunde inqaku.

Ezi ekuyo endulo ihlalwa zonke iintlobo amanzi. Evolution kwanyanzeleka ukuba batshintshe, kwaze oko kwakhokelela eziphila yokuqala beza elunxwemeni. Iintlanzi eziphila phantse kuyo yonke indawo. Zezona chordates inkulu zaseprayimari superclass. inzululwazi Total uyazi iintlobo ezingaphezu kwe amabini amawaka yezi zilwanyana.

Fish - zezilwanyana zinegazi elibandayo. Baxhomekeke kakhulu kwi lobushushu kokugquma ke, isantya iinkqubo zawo pathways kuyahlukana nedlela kwiimeko iqondo lobushushu. Ebusika, xa amanzi lwentaba- ukuya zero degrees kunye ngezantsi, intlanzi eze nje wehla waya ezantsi ichibi, ngenxa yokuba kusoloko kukho ubushushu zero.

Fish and Frog amacandelo ebalulekileyo amatsheyini ezininzi ukutya. Abazange awadli kwezinye izinto izityalo kunye nezilwanyana, kodwa bona babe ukutya ezidla. iintlanzi ezininzi abalithimbayo ebantwini. Ngenxa yokuba kukho inani elikhulu yezi zilwanyana kufa ngenxa fishings, ezinye iintlobo zeentlanzi sele idwelisiwe njengoko ezisengozini okanye zanyamalala ebusweni Yomhlaba.

amasele

Izilwanyana eziphila emhlabeni nasemanzini - izilwanyana yokuqala, ubeke unyawo phezu komhlaba. Aphile zombini emhlabeni kunye namanzi. Ngoxa iintlanzi eziphila amtyuba namnandi amanzi, izilwanyana eziphila emhlabeni nasemanzini zingafunyanwa kuphela kwi kwemilambo.

Fish kunye frog eziliqela ezifanayo nezahlukileyo. Izilwanyana eziphila emhlabeni nasemanzini ziye zathi imilenze ezivumela eziphila ukutsiba phezulu. Ulusu lwabo ze, wayifulela yencindi yomlomo. Zinelungelo umbono ephuhliswe kakuhle - isinceda ukuba uqaphele amaxhoba esuka ubambisa kude uze ulwimi zakhe ezinde ancamathelayo. Amasele zizilwanyana zinegazi elibandayo, ngoko incopho yawo umsebenzi kule nyanga zishushu. Amaninzi ukuba inokufumaneka imigxobhozo, amahlathi kunye namachibi ezahlukeneyo.

ukufana

Ichaza ukufana phakathi iintlanzi kunye amasele, asinakho ukuba bona ngokwabo, hayi kuphela ngaphandle kodwa ngaphakathi. Oku kubonakala kwinto yokuba tadpoles abasandula ukuqanduselwa bafana ukuma intlanzi encinci. Xa omdala yokufana kwawo kubangwa kukuba iintloko ezi izilwanyana kakuhle singena esiqwini. Xa amasele, kukho enye vertebra wesibeleko abangatshatanga intamo kumculo intlanzi isiciko angasemva.

Ukongeza, intlanzi, kunye isele kufuneka lisikwe yomlomo kunye namehlo amakhulu. Le yenye ezifana icace kubume sangaphandle. Njengoko ngokuba sinuses ngeempumlo zawo, ngoko eziphila emanzini kubo izibini ezimbini. Noko ke, ababini yempumlo zine amasele emlonyeni wakhe, lo gama zonke yempumlo iintlanzi obekwe phezu kwentloko yakhe.

Fish and Frog imisipha aphuhliswe kakuhle. Ukuba emanzini wayanyaniswe, intlanzi nentshukumo - ukusuka ukuqubha. Isibakala sokuba kubalulekile ukuhlala emanzini kwaye ayichase indlela yayo. Banalo izihlunu ukuba banoxanduva intshukumo yamehlo, engenamaphiko kunye nezinye iindawo imizimba yazo.

Abo kunye nabanye abameli kwezilo zizala. Ngelo xesha Qhotsa intlanzi kunye tadpoles ke chordates. Zombini abameli izilwanyana ye zinegazi elibandayo, nto leyo ebenza ixhomekeke lobushushu ngeenxa zonke.

umahluko

Njengoko kukhankanyiwe ngaphambili, intlanzi kunye isele ilifa zombini izinto ezifanayo nezahlukileyo. Baya kuza ngaphandle kunye nezo ziphuma ngaphakathi.

Kuqala kwinto zonke, baya elungiselwe isakhiwo amathambo. Xa amasele babe vertebra wesibeleko, xa angekhoyo iintlanzi eziphila kwi ukakayi ingamathambo ezincinane. Frog intloko movably idityaniswe umzimba. intambo yakhe emqolo nezikhuseli ajike eziliqela. Ngoxa iintlanzi kufuneka iigilizi, izilwanyana eziphila emhlabeni nasemanzini akukho amathambo kumculo okanye ezineziciko zabo.

Muscle skeleton nayo eyahlukileyo kwezo zezilo. Ngenxa yokuba isele akukho nje idada emanzini, kodwa ukuhamba phezu komhlaba, izihlunu imilenze yakhe bayaphuhliswa kakuhle. Ukongezelela, oko zinokuwehlisa ze aphakamise intloko yakhe. Izilwanyana eziphila emhlabeni nasemanzini angashenxela kumacala ahlukeneyo, ngelixa intshukumo kweentlanzi obungabangeli mdla nento entsha yinyoka. Anyuke amasele lawo Umahluko nentlanzi siyifumana isakhiwo kwamehlo abo. Isibakala sokuba iintlanzi yokuba tyaba kwaye eziphila - khaxa.

Imilo umzimba izilwanyana zahlukile kakhulu. Okokuqala, imilo iimeko yomzimba wentlanzi, nto leyo inegalelo ngesantya eliphezulu intshukumo emanzini. abemi Isikhumba amanzi ngokuqhelekileyo alekwe esikalini, kunye eziphila isikhumba ze. Le yenye umahluko ezininzi phakathi emanzini nentlanzi.
