Umthelela Wokugawulwa Kwamahlathi Ezinhlobonhlobo Zezinto Eziphilayo Amanani aqhubekayo nasheshayo okugawulwa kwamahlathi emhlabeni wonke abe ngumthombo omkhulu wokukhathazeka kwezazi zemvelo, izazi zemvelo, kanye nabenzi benqubomgomo. Amahlathi, ayekade egubungele uMhlaba ngohlaza oluluhlaza, ancipha ngesivinini esesabekayo ngenxa yokugawulwa kwemithi, ezolimo, intuthuko yasemadolobheni, kanye nokushintsha kwesimo sezulu. Lokhu kulahlekelwa okungapheli kwe… Funda kabanzi

Umsebenzi wama-Enzyme ku-Cellular Metabolism Isingeniso Ama-Enzyme ayizinto ezibangela ukwakheka kwezinto eziphilayo ezibalulekile empilweni. Adlala indima ebalulekile ekwenzeni lula ukusabela okuhlukahlukene kwamakhemikhali okudingekayo ekusetshenzisweni kwe-metabolism yamaseli, okuhlanganisa konke ukusabela kwamakhemikhali okwenzeka ngaphakathi kweseli eliphilayo ukuze kulondolozwe impilo. Lokhu kusabela kubalulekile ezinqubweni ezifana nokukhiqizwa kwamandla, ukwenziwa kwezinto eziphilayo … Funda kabanzi

Izindlela Zokuzivumelanisa Nezilwane Ezindaweni Zasehlane Amahlane aphakathi kwezindawo ezimbi kakhulu nezinselele kakhulu eMhlabeni, ezibonakala ngezikhathi ezinde zokomisa, ukushisa okukhulu, kanye nezitshalo ezincane. Naphezu kwalezi zimo ezinzima, izinhlobo ezahlukene zezilwane zasendle azizange zikwazi ukusinda kuphela kodwa zichume ezindaweni zemvelo zasehlane. Lesi sihloko sihlola izindlela ezithakazelisayo zokuzivumelanisa nezimo … Funda kabanzi

Isakhiwo kanye Nomsebenzi Wezicubu Ze-Xylem Ne-Phloem Ezitshalweni Isingeniso: Izitshalo, izisekelo zokuphila kwasemhlabeni, zikwazi ukusinda nokuchuma ezindaweni ezahlukahlukene ngenxa yenethiwekhi eyinkimbinkimbi yezicubu nezinhlelo. Phakathi kwalezi, izicubu ze-xylem ne-phloem ziyisisekelo, zidlala indima ebalulekile ekuthuthweni kwamanzi, izakhamzimba, kanye nokudla … Funda kabanzi

Izinzuzo Nezingozi Zobunjiniyela Bezakhi Zofuzo Ezitshalweni Zokudla Ubunjiniyela bezakhi zofuzo ezitshalweni zokudla kube yisinyathelo esiguqukayo emkhakheni wesayensi yezolimo, okunikeza amathuba okunqoba ukushoda kokudla, ukuthuthukisa inani lokudla okunomsoco, kanye nokuthuthukisa ukumelana nezinambuzane nezifo. Kodwa-ke, izingozi ezingaba khona ezihlobene nezinto eziphilayo eziguqulwe izakhi zofuzo (ama-GMO) zivuse impikiswano ebanzi … Funda kabanzi

Izici Zemvelo Ezithinta Ukuvezwa Kwezakhi Zofuzo Ukusebenzisana phakathi kwemvelo nokubonakaliswa kwezakhi zofuzo kuyisici esiyisisekelo sebhayoloji esiye sathakazelisa ososayensi amashumi eminyaka. Izakhi zofuzo zomuntu, eziqukethe izakhi zofuzo ezilinganiselwa ku-20,000 kuya ku-25,000, zinikeza uhlelo lwentuthuko yethu, i-physiology, kanye nokuziphatha. Kodwa-ke, akuzona zonke lezi zakhi zofuzo “ezivuliwe” noma … Funda kabanzi

Ukusetshenziswa kwe-Molecular Biology ekunakekelweni kwezempilo I-Molecular biology, igatsha le-biology eliphathelene nesisekelo sama-molecule somsebenzi we-biological, livele njengesisekelo sokuqonda izinqubo zokuphila. Ukusetshenziswa kwalo ekunakekelweni kwezempilo kushintshe indlela esixilonga ngayo, ekwelapheni, futhi sivimbele izifo, sinikeza izixazululo ezinembile, ezisebenzayo, nezizimele. Lesi sihloko sizohlola … Funda kabanzi

Amaphethini Efa Lezifo Zofuzo Izifo zofuzo zingaqondwa ngesayensi eyinkimbinkimbi yezakhi zofuzo, okuwucwaningo lokuthi izici nezimo zidluliselwa kanjani kusukela kwesinye isizukulwane kuya kwesinye. Ifa lezakhi zofuzo lilandela amaphethini athile, athonywe yizici ezahlukahlukene njengohlobo lwezakhi zofuzo ezihilelekile, indawo yalo ku… Funda kabanzi

Indima Yama-Microorganisms Ekuvuthweni Kokudla Ukuvutshelwa kokudla kuyinqubo ethakazelisayo neyinkimbinkimbi ebilokhu isetshenziswa ngabantu iminyaka eyizinkulungwane ukuze kulondolozwe, kuthuthukiswe ukunambitheka, futhi kuthuthukiswe inani lokudla okunomsoco. Ama-Microorganisms—izinto eziphilayo ezincane, ezivame ukuba neseli elilodwa njengebhaktheriya, imvubelo, kanye nezikhunta—adlala indima ebalulekile kule nqubo yokuguqula. Imisebenzi yawo ye-metabolic iqhuba i-biochemical … Funda kabanzi

Amasu Esimanje ku-Biotechnology Yezolimo Emkhakheni oshintsha ngokushesha we-biotechnology yezolimo, amasu esimanje aguqula indlela esitshala ngayo ukudla, siphatha ngayo izitshalo, futhi siqinisekise ukuvikeleka kokudla kwabantu bomhlaba wonke abakhula njalo. Lesi sihloko sihlola izindlela eziningi ezintsha eziguqula ezolimo njengamanje, kusukela ezintweni eziphilayo eziguqulwe izakhi zofuzo (ama-GMO) kuya ekulimeni okunembile, … Funda kabanzi
