Ngelixa Ufudo oluthambileyo Baphefumla umoya, bachitha uninzi lobomi babo emanzini. Naxa amadama namachibi abiza amakhaya ukuba ayomile, wona baya kubamba iintloko zabo phantsi komphezulu wamanzi, ngamanye amaxesha iiyure ukuphela, umkhwa othe wadideka oosonzululwazi iminyaka. Enkosi kwingxelo ekhutshwe namhlanje kwi Ijenali yeBhayiloji yovavanyo , abaphandi abasakhubeki. Zilungile, nangona kunjalo, ziluhlobo oluthile lwentengiso, njengoko Uphononongo lubonisa ukuba xa zizi dunk iintloko, kungenxa yokuba zichamela emanzini ngemilomo yazo. Ke malunga nokuba yimfihlo encinci, bafo? Jeez!
Ukufumanisa ngqo ukuba uvela phi umchamo wofudo, abaphandi bathenga iimfudo ezineshelfu zaseTshayina kwimarike yalapho, ngaloo ndlela besindisa izilwanyana ezirhubuluzayo kwindawo abayiqhele ukuya kuyo njengesuphu. Akukho nto iza simahla, nangona kunjalo, kwaye ukubuyisela ukuhlangulwa kwangexesha, oofudo babenyanzelekile ukuba bayiguqule imfihlo yendlela abazichamela ngayo, ngokungafaniyo nohlobo lwe-gnarlier unqwenela ukunika intlanzi yeentsomi. Iifudo zazikhutshelwa emanzini apho zikhululeke kakhulu kwaye azinikwa kwanto ngaphandle komgxobhozo omncinci. Ngelixa ichaphaza lomzuzu lalingenamzuzu kubo ukuba bangene kulo, lababonelela ngendawo yokuba bazidube iintloko, abazenza kangangemizuzu eli-100 ngexesha, apho babengekho nje ukukhupha i-urea, kodwa behlambulula imilomo, kuba enkosi uthixo ngaloo nto.
Xa iqela lilinganise amanqanaba e-urea edamini emva kwentloko kofudo, bafumanisa ukuba amanzi ayaphuphuma ngofudo. Olu phononongo lwalandelwa luvavanyo lwemfuza olwafumanisa ukuba iimfudo zivakalisa uhlobo lokukhutshwa kwe-urea emilonyeni yazo, ziqinisekisa ukukrokrelwa ukuba oofudo, ngokwenene, bukhulu ngokupheleleyo.
Ngelixa iimfudo ezithambileyo zigqitha urea kwezinye izintso ezifana nam nawe, incinci kakhulu, ifikelela kwi-6% yomchamo opheleleyo oveliswa zizilwanyana. Eliseleyo lishiya ngemilomo yawo. Le ndlela yenoveli yokuthatha ukuvuza ayisiyonto ikhethekileyo kwibinzana elibetha entloko. Iindidi zeentlanzi ziyaziwa ngokukhupha i-urea ngemilomo yazo ngendlela efanayo, kodwa eli lixesha lokuqala ukuba isimilo siqwalaselwe kwisirhubuluzi.
Okwangoku akukaqondwa ukuba kutheni ufudo luza kuphuhla olu tshintsho, kodwa iqela lophando likrokrela ukuba olu phawu lunceda oofudo ukuba baphumelele emanzini amtyuba, angenakusela bathanda ukuwabiza njengekhaya. Amanzi amatsha yinto eshushu kwezi ndawo, kwaye ukhupha i-urea ngomlomo kuthetha ukuba ufudo lunokuhlambulula imilomo yalo kunokuba lusele, ukunciphisa inani lamanzi ekufuneka elisebenzisile.
Ukuba unomdla wokufunda ngakumbi malunga nolu fudo luncinci kunye neendlela zalo zokuhlambela- kwaye ngokwenene, khange yenzeke kuthi ukuba ngekhe ubekhona- ungafunda into engabonakaliyo Apha .
(nge Ukhuseleko )
- Umchamo kunye neminquma kunokusisindisa kutshintsho lwemozulu
- La maqanda afakwe kumchamo wamakhwenkwe amancinci yinto emnandi e-China, impikiswano yakho ayisebenzi
- Nantsi indoda eyonwabisayo enxibe isinxibo sefudo
