Amaqanda akhiwa ezibelethweni zomama abaningi abayizilwane. Ngaphakathi kweqanda kunengqamuzana elincane leqanda. Lokhu kubangela ukuthi isilwane sikhule lapho iduna seliyivundisile. Amaqanda atholakala ezinyonini nasezilwaneni eziningi ezihuquzelayo, ngaphambili futhi kuma-dinosaurs. Izinhlanzi nazo zizalela amaqanda, kanye nama-arthropods, okungukuthi izinambuzane, ama-centipedes, izinkalankala, nama-arachnid, kanye nezinye izinhlobo zezilwane eziningana.
Iqanda liqukethe ingqamuzana elincane legciwane. Lena ingqamuzana elilodwa nje elingabonwa ngeso lenyama. Eduze kwayo kukhona ukudla okudingwa yisilwane esincane size sichanyuselwe. Ngaphandle kunesikhumba. Amaqanda anjalo athambile njengerabha, njengamaqanda ofudu. Amaqanda ezinyoni asenegobolondo eliqinile lomcako esikhumbeni.
Izingxenye ngazinye zeqanda lesikhukhukazi eliqhekezwe lavuleka kulula ukuzibona: ingxenye ephuzi, i-yolk, ingaphakathi. Ngezinye izikhathi ibizwa nangokuthi "i-yolk". I-yolk isongwe ngesikhumba esincanyana, esisobala, esifana noswidi. Lesi sikhumba sisontiwe ndawonye ngaphandle futhi sinamathele egobolondweni leqanda. Ngaleyo ndlela i-yolk ayinyakazi kakhulu. I-yolk intanta kumhlophe kweqanda. Lokhu ngezinye izikhathi kubizwa ngokuthi "amaprotheni". Kodwa lokho akucaci ngoba amaprotheni ayinto eyenzeka nasenyameni, isibonelo.
Esikhumbeni se-yolk, ungabona ngokucacile idiski yegciwane elimhlophe. Kungase kudingeke ukuthi uphendule i-yolk ngokucophelela. Itshwele likhula kudiski ye-embryonic. I-Yolk kanye neqanda elimhlophe kungukudla kwayo kuze kube yilapho ichanyuselwa.
Omama abayizilwane babekela amaqanda abo lapho sebevuthiwe. Ezinye izilwane zifukamela amaqanda azo esidlekeni njengoba kwenza izinyoni eziningi. Umama uvame ukufukamela amaqanda, ngezinye izikhathi ashintshane noyise. Ezinye izilwane zizalela amaqanda ndawana thize bese ziwalahla. Ngokwesibonelo, izimfudu zigqiba amaqanda azo esihlabathini. Ilanga libe selinikeza ukushisa okudingekayo.
Izilwane ezincelisayo azinawo amaqanda. Baneqanda elilodwa kuphela noma iseli legciwane. Iyingqamuzana elilodwa, elincane futhi alibonakali ngeso lenyama. Kwabesifazane, iqanda livuthwa cishe kanye ngenyanga. Uma eke walala nowesilisa ngalesi sikhathi, ingane ingase ikhule. Umntwana udla ukudla okusegazini likanina.
Yimaphi amaqanda adliwa abantu?
Amaqanda amaningi esiwadlayo aphuma ezinkukhuni. Amanye amaqanda ezinyoni, isibonelo, avela kumadada. Ngokuvamile lezi zinyoni zihlala emapulazini amakhulu, lapho zinendawo encane futhi zingakwazi ukuphuma ngaphandle. Amatshwele esilisa abulawa ngokushesha ngoba angeke azalele amaqanda. Ama-Vegans acabanga ukuthi lokho kubi ngakho-ke awawadli amaqanda.
Abanye abantu bathanda amaqanda ezinhlanzi. Eyaziwa kakhulu ibizwa nge-caviar futhi ivela ku-sturgeon. Ukuze aqoqe la maqanda, umuntu kufanele avule i-sturgeon. Yingakho i-caviar ibiza kakhulu.
Isibonelo, abantu badla amaqanda abilisiwe ekuseni. Epanini, wenza amaqanda aqhutshiwe noma amaqanda athosiwe. Kodwa-ke, sivame ukudla amaqanda ngaphandle kokuwabona: ezimbonini ezinkulu, i-egg yolk kanye ne-albuden kulungiswa ukudla.
