Ucwaningo: jellyfish siphile phakade?

Sekuyisikhathi eside abantu kwaba befuna le elixir ukungafi. Ubufakazi besayensi bakamuva kusikisela ukuthi le planethi yethu enhle uyisidalwa ukuthi singaphila phakade. Lokhu-ke, kubonakala Sekuyisikhathi eside, wafunda futhi ubone jellyfish, noma kunalokho, isidalwa esincane okuthiwa nutrikula. Ingabe ufuna ukufunda indlela ukuthola jellyfish ophila kuze kube phakade?

ekudalweni zigcwele

Medusa nutrikuly eyaziwa emhlabeni yesayensi isikhathi eside. Incazelo yokuqala lesi silwane uvele yekhulu nesishiyagalolunye. Ukuveza kanye umjikelezo wokuphila ovela nutrikuly ngempela abavamile. Njengazo zonke jellyfish, isidoda kokukhulelwa kwenzeka phezu kolwandle, bese uvule iqanda, kuphuma iqhimiza elinemilenze. Khona-ke planuly ukwehlisa kwenzeka ezansi kanye kumiswa polyp, okuyinto uyashiywa jellyfish amancane ophila kuze kube phakade. Izithombe salezi zidalwa lapha ngenzansi.

Yangaphandle umbono jellyfish Turritopsis nutricula zingezona ezibonakalayo, kunalokho, singasho ukuthi uyisidalwa yesikhumbuzo. Kuyinto ububanzi isambulela esingaphansi 5 mm, okuyinto lizungezwe tentacles mncane. Ngo jellyfish abasanda kuzalwa kubo 8 kuphela, khona-ke njengoba umuntu omdala has izingcezu 100. libuye libe indawo cruciform obomvu kwakhiwa okuyinto phakathi isambulela ngokweqile, izitho zokugaya ka jellyfish. Izinsana nutrikuly Usayizi 1 mm.

ukutholakala emangalisayo

Ukuphela leminyaka elidlule kwaphawulwa kwatholakala okuthile okumangalisayo. It kuvela ukuthi jellyfish lokuphila phakade. Ukutholwa wenza Italian Fernando Boero. Ukunquma ahlanzekile ukhohlwe kanye aquarium, ososayensi wathola polyp eziyinqaba. Lezi neziqu engavamile olufana jellyfish eziningi eziye zaphila aquarium, kodwa ngaphandle ihambe. Usosayensi sinqume ukuqhubeka ukuhlola, ngenkathi ezinye izidalwa e aquarium wafa. Ukugcwalisa ngayo olwandle, Boero wabukela ama-polyp. Ngemva kwesikhathi esithile, baqala ukuthuthukisa, futhi ngenxa yalokho azalelwa jellyfish amancane nutrikuly.

Sekube nezigameko eziningi ezazibonakala zingenakwenzeka - nutrikuly waphenduka umjikelezo waso ukuthuthukiswa. kwakwaziwa ukuthi konke jellyfish abe isinyathelo sokugcina ngaphambi kulokhu - esigabeni zizalela. Iningi coelenterates izilwane, hhayi kuphela kubo, ukuzalwa amaqanda avundiswa noma amaseli kuholela ukufa kwabantu abadala. Futhi vele zikhona izilwane ezisencane, jellyfish izibungu kukufake polyp, futhi kakade bazalwa jellyfish encane. Ukuvula Boero yabuya wonke ulwazi mayelana jellyfish. Ngokwesibonelo, ososayensi baye bathola jellyfish ophila kuze kube phakade.

Ukuguquguquka kwempilo

Abamele lolu hlobo, efana nezinye izinhlobo zezinto eziphilayo hydroid ihlolwe 2 esiteji. Eyokuqala iqala ukuthuthukiswa izibungu emva kokukhulelwa. Khona-ke izibungu kuxazululwe phezu phansi olwandle abanjwe esikhaleni lapho ama-polyp jikisa. Ngakho, kukhona amakoloni yonke jellyfish ngokubukeka sifana lokuphotha noma Mace. Kulesi sigaba ukuthuthukiswa polyp akha uhlobo skeleton, ngesikhathi abakuphela kukhona esingokwemvelo nge tentacles Jellyfish amaseli kabuhlungu. Ngakho, yonke koloni uyakwazi ukudla izidalwa ezincane.

Isigaba sesibili iqala ukuhlukana kwazo abasha jellyfish polyp. Ngakho, i-jellyfish encane uqale ukuhola evamile ngathi indlela yokuphila. Ezinyangeni ezimbalwa nje, they finyelela khula ngokobulili, futhi lonke inqubo iphindwa. Kangakanani lokho kwenzeka ukuthi jellyfish saba siphile phakade? Ngokuthakazelisayo, jellyfish linezindlela ezengeziwe ukulondoloza zilwane.

Izici jellyfish

Kulondolozwe ukuphila lihlotshaniswa ikhono nezidalwa hydroid ukuze inqubo yokutakula. Sekuyisikhathi eside kwaziwa ukuthi uHlelo jellyfish esikhathini esifushane Ungayibuyisa izingxenye labalahlekile umzimba. Ucwaningo wafakazela ukuthi Imi zibe yizicucu jellyfish uyakwazi nokuzala ngokwayo. Le nqubo ibizwa ngokuthi transdifferentiation yokutakula. Eqinisweni, kusukela kwesinye uhlobo cell ingaqala omunye, okusho ukuthi kwakuthiwa zonke jellyfish lokuphila phakade. Nokho, la mandla kufanele nezinye izinto eziningi kangaka. Izibankwa kalula sikhule ngokwakho nomsila entsha, kanye nabacwaningi bayakwazi namuhla kusukela stem cells ukuze ikhule izitho ngabanye.

Kodwa nekhono se-jellyfish saba nutrikuly abuyisele zonke umzimba wakho iyingqayizivele ngempela. Umzimba womuntu ungakwazi ukuphinda inqubo i isibalo esingapheliyo izikhathi uhlale phakade abasha. Lezi zinqubo futhi wanikeza ososayensi nokucabanga ukukholelwa ukuthi jellyfish lokuphila phakade.

Namuhla, ososayensi baye ngeso elibukhali lolu hlobo jellyfish ukuze uhlole kabanzi inqubo rejuvenation. Eplanethini yethu emangalisayo, kusenabantu angaziwa yabaningi kukho nawabantu abangazange lalingakambulelwa izimfihlo zabo.
