I-White, i-Brown, Green iqanda lenkukhu: Yintoni umahluko?

Tsala icandelo le-EGG levenkile egcweleyo okanye imakethi yamaFama, kwaye uza kuqaphela iibhokisi zamaqanda ezahlulwe zangaphantsi kwaye zimdaka, ngamanye amaxesha amaqanda aluhlaza okanye amaqanda aluhlaza okanye amaqanda aluhlaza okanye amaqanda aluhlaza. Kodwa xa sele befikile kwiplate, mhlawumbi, okanye babhakwe kwikhekhe, kunzima ukuxelela umahluko. Ngapha koko, yintoni umahluko phakathi kwamaqanda anegobolondo ngemibala eyahlukeneyo?

Le ayisiyonto emfutshane okanye yerayisi. Amaqanda ansundu akangabi ngaphezu koko "kwendalo," namaqanda amhlophe akakhange ahonjiswe nge-bleach. Zombini ezahlukeneyo zenzeka ngokupheleleyo ngokwemvelo, njengoko benza amaqanda enkukhu eluhlaza. Kodwa inene, onke amaqanda enkukhu ayalingana ngaphakathi. Ke yintoni ebangela imibala eyahlukileyo yeqanda phakathi kohlobo lwentaka?

UGqr Justin Fowler, unjingalwazi kwiYunivesithi yeSebe lezeNzululwazi laseGeorgia, ukhanyise ukukhanya kwizinto. "Imibala eyahlukeneyo, okanye ubukho bamabala okanye ubukho bendawo okanye ukukhonkxa, yihla uye kwimfuza yentaka, utshilo.

"Iinkukhu zemfola ze-phyhorn (ezenza uninzi lweshishini leqanda leqanda e-US), ngelixa i-orphingtouth okanye i-Plymouth Rocks ibeka amaqanda ansundu. "I-Ameraubanca i-Ameraubanca ine-pigment ekwaziyo ukunqanda igobolondo iqanda leqanda kwaye lenze amaqanda elinemibala eluhlaza okwesibhakabhaka enombala ngaphakathi nangaphandle kweqokobhe."

Ngaba ufuna ukwazi ukuba inkukhu ethile iya kuphumeza iqanda elimhlophe okanye iqanda lemibala? Vavanya ibhola yenkukhu. . Kwaye rhoqo kunokuba, iinkukhu ezinezilwanyana ezilula zihlala zineentsiba ezimhlophe, kwaye ke amaqanda amhlophe, ngelixa ineentsiba ezinemibala kunye neentaka zihlala zivelisa amaqanda anemibala.

Uvela phi lo mbala? Apha kulapho kuqonda ukuba iqanda libalulekile. I-Yolks yenkukhu, okanye i-OVA, kwi-ovari yenkukhu. I-Ovum esekwe ngokupheleleyo iya kushiya i-ovary kwaye ifakwe kwi-Ovisipect. Le nxalenye yenkqubo yokuzala yenkukhu ineendawo ezilandelelanayo ezilandelelaneyo ezihambahamba kwi-yolk idlula ehlabathini ngaphandle, kodwa yeyesine - echaphazela umbala weqanda. Kulapho iqhinga lelokwala i-ovum.

"Iqokobhe lazo zonke iiqanda zenkukhu zenziwa nge-calcium carbonate, i-crystal emhlophe ngombala," utshilo u-ufir. "Ke onke amaqanda, ubuncinci ekuqaleni, mhlophe. Nasiphi na into esiyibonayo eminye imibala ebekwe kwi-pigmet, emva kokuba idlwengulwe i-ovingg. Uyabona Oku ukuba uvula iqanda elimdaka kwaye ujonge ngaphakathi kwiqokobhe, iya kuba mhlophe. "

I-pigments ezimbini zinoxanduva lokufumana umbala weqanda yeqashi. Imiza yeGreens kunye neBlues zibangelwa yi-biliverdin, ngelixa iProtporphyrin inoxanduva lokubomvu-mdaka.

Inkqubo efanayo yokufaka iqanda ibambelele kuyo yonke iintaka ezinamaqanda anemibala. I-American Robin (i-turdsus migatorius) amaqanda, umzekelo, luhlaza okwesibhakabhaka. Amaqanda abuhlungu epiarre ye-murre eqhelekileyo (i-aalge eriya) anokudlala i-hue eluhlaza okwesibhakabhaka, ube ne-hicked okanye uqinisekise imiqobo emdaka.

Ngaba amaqanda enkukhu kufuneka agcinwe egudileyo okanye kubushushu begumbi? Kuxhomekeka ekubeni uhlala kwilizwe (i-Australia, eJapan naseMelika, umzekelo) efuna amaqanda ahlanjululwe. Le nkqubo ikhusela kwi-salmonella, kodwa isusa i-waxy sholl ihamba ngokuthintela amaqanda nxamnye namaqanda, oko kuya kunyanzelisa ukuqiqa.

Yintoni engakumbi, ukuba unayo nayiphi na into enomdla kwi- Eva ye-Eva ye-Eva ye-Eva okanye i- Eva Sud Pad & I- EVA PROCCON PAD , nceda ukhululeke ukunxibelelana nathi.
