Basebumnyameni sisixokelelwano esivalekileyo yokusila unayo nayiphi na izilwanyana?

Ixabiso kwinkqubo yokwetyiswa yokucolwa kwezinto eziphilayo zicwadi kunzima kakhulu ukuba zazi. Eneneni, ukuba khona ngaphandle kwalo nje akunakwenzeka. Kweli nqaku siza kuxubusha ngokweenkcukacha undoqo kwezi nkqubo, ingakumbi isakhiwo kunye neentlobo zeendlela zokwetyisa kumaqela ezahlukeneyo zezilwanyana.

Yintoni na umzimba?

Okunomongo inkalo kubalulekile eento zonke eziphilileyo kunye ukuphefumla, intshukumo, buphindwe bhetyebhetye. Imisebenzi kwinkqubo yokwetyisa, kuqala, kukuba kubetheleleke nethe. Bengena emzimbeni, ukuba eziguqulelwe, uze output kulowo. Lo msebenzi wenziwa kuphela kwinkqubo yokwetyisa. Ngokomzekelo, ngenxa yokuba umsebenzi yokuphefumla kuzo zonke izihlunu zomzimba zabonelelwa ioksijini ize ivelise carbon dioxide.

Imisebenzi yenkqubo wokugaya

Kwinkqubo yokwetyisa, iiprotheni, iikhabhohayidrethi, lipids, iityuwa izimbiwa, iivithamini kunye namanzi ifakiwe kuhlanganiselo iimveliso eyahlukeneyo phantsi ukuhlasela koomatshini nemichiza. Le proihodit ngenxa yokuba umzimba akakwazi lokugaya kubo ingatshintshanga. Ngoko ke, zonke izinto kwi wokugaya mazahlulwe zibe ezincinane, iye yangena egazini wendele. Ngenxa yoko, umzimba ufumana amandla ukuze zonke iinkqubo zobomi.

Ngaba bukho ubomi ngaphandle inkqubo kokudla kunokwenzeka?

Ekuqaleni lo mbuzo usenokubonakala engaqhelekanga. Kodwa kukho izilwanyana zingeyomfuneko sokudiliza izondlo. Ziyifumana alungele-eyenziwe. Oku ziimpethu ingakumbi olwaye lwamfimfitha. Zihlala emathunjini ezilwanyana kunye nabantu imibhobho. Umzekelo, ummeli Amaphalo zeklasi - tapeworm lenkomo sitsala izondlo iziciko. Ngelo xesha linye yenza umonakalo elibalulekileyo umkhosi ephilayo, etheni ukhetho ukutya kwakhe.

Iintlobo kwe nkqubo wokugaya

Ubume inkqubo yokwetyisa ibe iintlobo. Kuxhomekeke indlela lokondla. izilwanyana ezininzi ngaye kwinkqubo yokwetyisa. Oku imelwe ityhubhu enobude ezahlukeneyo, lokuvula eziphelweni zombini. Ngenxa yoko, ukuba kubekwe ngendlela esanyisayo yomlomo umngxuma, pharynx, kuvuleke iminxunya, isisu, emathunjini kunye ezimpundu, apho yimani ukutya undigested. Basebumnyameni sisixokelelwano esivalekileyo yokusila zonke amalungu uhlobo Coelenterates. na indlela elungelelaniswe ngayo?

sisixokelelwano esivalekileyo wokugaya

Scheme isimiso sokugaya sohlobo evaliweyo ilula kakhulu. Olu umlomo kunye kwisisu emathunjini. oko Undigested intsalela ukutya ngaphandle kokuba ngomlomo. ivaliwe basebumnyameni inkqubo yokucola abe hydra, jellyfish kunye polyp. Bona iindlela ezahlukileyo zobomi. Kodwa ke isakhiwo lweenkqubo ilungu enxulumene nga ngamandla. Bonke ngamarhamncwa. Bancede ukuba enithiyela ngazo nemisipha, leyo ezikhethekileyo iiseli ehlabayo. Ziqulethe njengezingxobo kunye vulu etsolo, ephothiweyo, ophela kuyo inaliti elibukhali. Ngomhla kumphezulu weeseli enjalo iinwele onovakalelo. Xa kufikwa emzimbeni yexhoba, ngomsonto abuhlungu reflex kunye ijikelezisa force kwaye iluma emzimbeni imveliso, ezikhubazayo kuyo. Ukuba ubukhe wakha wavakalelwa esilondeni of jellyfish, ungakwazi ngokulula indlela isiphumo ngokuseka. Ngokuvelisa ukutya, ngomsonto abuhlungu afe ngoko nangoko kwaye engasakwazi ukwenza imisebenzi yayo. Ifom entsha kunye uhlobo iseli eyahlukileyo - imfundo.

uhlobo Coelenterates

Onke amalungu ale yunithi abe umngxuma ngendlela ethunjini silwanyana. Ngesi feature, isakhiwo, yaye enxulumene igama labo. Basebumnyameni sisixokelelwano esivalekileyo yokusila ezi hydra kakhulu amanzi. Bona apha yokuphila. yedwa yazo statically ibekwe kwi zeendawana naphezu icala somzimba emlonyeni. It ingqongwe nemisipha, ezisetyenziswa ukufaka ixhoba. Ezi kwezilwanyana, kwindawo isinambuzane intlanzi encinci. Xa ngokusebenzisa Mpondwana ngaphakathi sayo isisu, ukutya phantsi isenzo enqanda ukuba ziveliswa iiseli ezikhethekileyo glandular. Phantsi yempembelelo ezi ehlanganisa zebhayoloji, ukuba uqalisa ngamaqhekeza amancinci. Le nkqubo iqhubeka iiseli hydra yokwetyisa udonga engaphakathi omzimba abe pseudopodia. ekugayeni laphela vacuoles ezizodwa. A izinto kusala kwazona ngomlomo. Ngokufanayo, kwenzeka kunye jellyfish kunye polyp, akuba ivaliwe inkqubo yokwetyisa.

Flatworms uhlobo

Basebumnyameni sisixokelelwano esivalekileyo yokusila zonke amalungu uhlobo ziimpethu tyaba. Oku limelwe emathunjini ngaphambili nophakathi, nesiphelo ongayaziyo. Yona ke ukufunxeka kunye nokwabiwa ukutya emlonyeni. Ngaphandle kokuba flatworms idinga uzuko sisidleleli kakhulu eziyingozi zabantu kunye nezilwanyana, phakathi kwabo nabo kukho iintlobo simahla-ophilileyo. Ezi ziquka planarians zaselwandle kunye amanzi. Kwimeko-bume zasemanzini uzingela hydras, kwezilwanyana, izilwanyana, saselwandle esineqokobhe kwindawo kwezinambuzane. Ke amaxhoba sithimba ngendlela engaqhelekanga. khasa Planarian emzimbeni yexhoba, babambelele nkawu zabo ngomlomo kwaye usebenzise ukuba ndimanyise yonke imixholo kwixhoba. Oku kuyenzeka kuba omnye iimpawu ezingaqhelekanga zesakhiwo. Isibakala sokuba emlonyeni flatworms ezamahala ibekwe kwi isisu sabo.

Ngenxa yoko, isakhiwo ometyiso ngokuyintloko kuxhomekeke kwindlela ngesondlo yezilwanyana. Kwaye coelenterates, kunye flatworms ezihlala amtyuba namnandi, abantu zamarhamncwa. inkqubo yazo yokwetyisa ungaveli zivaliwe kwaye lizisa umngxuma okanye tube ne indawo enye ezinikeleyo apho ukutya nakwesiphi kwaye, emva kokuguquka kwaye salawo.
