– Ososayensi bathole ukuthi uhlobo lwenhlanzi yolwandle abalubiza ngokuthi i-Turritopsis Dohrnii alufi.
– Lokhu akuhambisani yini nendima ethi, “Yonke imiphefumulo iyokufa”?
Mthandiwe, mzalwane wethu,
Kunzima ukuthola imingcele yolwazi olunjalo, okungukuthi, ukusho ukuthi lesi sikhathi sokungafi sisho ukuthini. Uma kwenzeka into enjalo, ake sibheke ukuthi ingabe kukhona yini okungqubuzana neKoran:
I-Quran ithi:
Siyabona izinhloso zayo kuleli vesi nakwezinye izindima ezifana nalo.
– Ake sizame ukuqinisa umthetho ngamanye amakhasi:
Ukuthi i-jellyfish enegama elithi *Turritopsis dohrnii* iyakwazi ukushintsha isakhiwo samaseli ayo ukuze iqhubeke nokuphila, akusho ukuthi ayifayo. Abantu nabo bayawashintsha amaseli abo. Iningi lamaseli abo liyashona bese liyavuka njalo ngemva kwezinyanga eziyisithupha, kanti cishe wonke amaseli abo ayashona bese ayavuka njalo ngemva kweminyaka eyisithupha, okubonisa isibonelo sovuko.
Ilanga nalo liyaphila ngomsebenzi we-fusion. Iningi lempilo yelanga, amandla akhiqizwa ngezigaba ezibizwa ngokuthi i-proton-proton chain reaction. Kulezi zigaba, i-nuclear fusion iyenzeka, iguqula i-hydrogen ibe i-helium. Inhliziyo yelanga yiyona kuphela indawo lapho ukushisa okukhulu kukhishwa khona nge-fusion. Amandla elanga angama-99% akhiqizwa lapha.
Njengoba ilanga liyinkanyezi yochungechunge olukhulu, amandla akhiqizwa ngokusabela kwenuzi okwenzeka njengamanje, akwazi ukumisa ngokuphelele ukuwa okubangelwa amandla adonsela phansi. Ngakho-ke, kukhona isimo sokulinganisela. Lesi simo sokulinganisela siqhubeka inqobo nje uma inkanyezi isochungechungeni olukhulu. Njalo ngomzuzwana, ezingeni lokushisa eliyizigidi eziyishumi nanhlanu ezingeni lokushisa elisembindini welanga, cishe amathani ayisithupha ekhulwini e-hydrogen aguqulwa abe i-helium.
Nokho, izifundo zesayensi zibonisa ukuthi njengoba zonke izinkanyezi zinomjikelezo wempilo othile, iLanga nalo linomjikelezo wempilo othile, ngeke likhiphe amandla phakade, ngelinye ilanga nalo lizokufa ngandlela thile kuye ngesimo salo. Ukuthi u-Turritopsis Dohrnii, uhlobo oluthile lwenhlanzi-yolwandle, uphila isikhathi eside, akusho ukuthi awufi.
Ezulwini, uJesu, emhlabeni, uKhizr, baphila izimpilo zabo ngaphandle kwemikhawulo yezinga lempilo evamile, izinkulungwane zeminyaka, kodwa nabo bayofa ngolunye usuku. Kufanele sibheke futhi u-Turritopsis Dohrnii, uhlobo lwenyoka yamanzi, ngaphansi kwalo mbono.
Lolu hlobo lwe-jellyfish lutholakala olwandle oluvulekile nasezilwandle. Lolu hlobo lwe-jellyfish, olunezinhlaka ezifana ne-jelly, lunomjikelezo wempilo ofana nalowo we-butterfly noma we-fern.
Njengoba nje umjikelezo wempilo wevemvane uqala ngeqanda, ube yisibungu, bese uqhubeka nempilo yawo njengovemvane. Ukufa kwevemvane akusho ukuthi impilo yalo iyaphela, ngoba impilo yalo iyaqhubeka ngandlela-thile ngeqanda lalo.
Ngokufanayo, umjikelezo wempilo we-fern uqala ngembewu, leyo mbewu iyahluma bese ikhiqiza isitshalo esibizwa ngokuthi i-prothallus, esincane ngosayizi, cishe ngosayizi wemali eyi-5-10 kuruş. Kuleso sitshalo, izitho zangasese zangaphandle zikhula, bese kwakheka amaseli esidoda namaqanda. Ukuhlanganiswa kwamaseli esidoda namaqanda kuveza isitshalo se-fern. Umjikelezo wempilo uyaqhubeka ngokukhiqizwa kwembewu yalesi sitshalo se-fern.
Lokhu kuqala ngesigaba se-polyp, bese kuvela i-medusa, okuyizinhlanzi zasolwandle ezintantayo. Kule medusa kuvela izakhiwo ezibizwa nge-planula, bese kuvela izakhiwo ezine-stolon, bese lezi zakhiwo ezine-stolon zikhiqiza izakhiwo ze-polyp, bese kuvela ama-polyp amaningi. Ngale ndlela, umjikelezo wempilo wezinhlanzi zasolwandle uyaphela.
Njengoba ubude besikhathi esiqondile sempilo yemvelo yezilwane ezikhule ngokugcwele bungaziwa lapha, kusetshenziswa igama lesiNgisi.
Lolu daba lwethulwa emithonjeni yezindaba ngale ndlela. Ngaphezu kwalokho, kwazanywa ukuthi kuveze ukuthi loku kuphambene nendima eku-Quran.
Kuthiwa isikhathi sokuphila kwabo asaziwa. Nokho, impilo yalezi zidalwa ngazinye iyophela uma ziliwa ezinye izidalwa.
Ngiyabingelela ngithandazela…
