I-bamboo ayaziwa nje kuphela njengezinto zokwakha ezingavamile kanye nezinto zasekhaya zendabuko, kodwa futhi njengengxenye ebalulekile ye-ecology yamahlathi. Amahlathi e-bamboo anikeza izinzuzo eziningi zemvelo nezomnotho, kanye … Funda kabanzi
Isakhiwo kanye Nomsebenzi We-Cytoskeleton I-cytoskeleton iyisici esibalulekile samaseli e-eukaryotic, enikeza uhlaka lwesakhiwo kanye nemisebenzi eyahlukahlukene yemishini. Kulesi sihloko, sizoxoxa ngokujulile ngesakhiwo se-cytoskeleton, izinhlobo zezinto eziyakhayo, kanye nemisebenzi ethile eyenziwa yi-element ngayinye ekugcineni ukusinda kweseli. Isakhiwo Se-Cytoskeleton I-cytoskeleton inezinhlobo ezintathu… Funda kabanzi
Umphumela Wemisebe Ekukhuleni Kwezitshalo Isingeniso Ukukhula kwezitshalo kuthonywa yizici ezahlukahlukene zemvelo, okuhlanganisa amanzi, ukukhanya kwelanga, izinga lokushisa, kanye nokutholakala kwezakhamzimba enhlabathini. Phakathi kwalezi zici, ukukhanya kwelanga kudlala indima ebalulekile ngoba, ngenqubo ye-photosynthesis, amandla elanga aguqulwa abe amandla amakhemikhali, izitshalo eziwasebenzisayo ekukhuleni nasekuzaleni. Kodwa-ke, hhayi... Funda kabanzi
Umthelela Wokungcola Kwamanzi Ezinhlanzini Ukungcola kwamanzi kuyinkinga ekhathazayo emvelweni emhlabeni jikelele. Lokhu kungcola akugcini nje ngokuphazamisa ikhwalithi yamanzi esiwasebenzisa nsuku zonke kodwa futhi kunomthelela omkhulu empilweni yezilwane zasemanzini, ikakhulukazi izinhlanzi. Izinhlanzi ziyingxenye ebalulekile yezindawo zemvelo zasemanzini kanye nomthombo wokudla kwabantu nezinye izilwane. Okuncane… Funda kabanzi
Imithonya Yemvelo Ekwakheni Kwezitshalo Isingeniso Ukwakheka kwezitshalo kubhekisela esakhiweni somzimba kanye nesimo sangaphandle sezitshalo, okuhlanganisa ubukhulu kanye nesimo samaqabunga, izimbali, iziqu, kanye nezimpande. Ukwakheka kwezitshalo akusikho nje umphumela wezakhi zofuzo noma ufuzo kodwa futhi kuwumphumela wokuxhumana nendawo ezungezile. Lesi sihloko sixoxa ngethonya lendawo ezungezile ekumeleleni kwezitshalo, ukuthi izimo ezithile zemvelo zingashintsha kanjani... Funda kabanzi
Izinzuzo Zabaphrotheyini Bezimboni Ezweni lanamuhla eliya likhula futhi lixhumene, ukunaka ubuchwepheshe be-biotechnology kanye nokuhlukahluka kwezinto eziphilayo kuyakhula. Iqembu elilodwa lezinto eziphilayo elivame ukunganakwa kodwa elinamandla amakhulu yibaphrotheyini. Abaphrotheyini bezinto eziphilayo beqembu elihlukahlukene kakhulu lezinto eziphilayo ze-eukaryotic, okuhlanganisa i-protozoa, i-algae, kanye ne-slime molds. Zingatholakala ezindaweni ezahlukene zokuhlala, … Funda kabanzi
I-Biology Yamaseli Neyezinto Eziphilayo: Izisekelo Zokuphila Isingeniso I-Biology iwukufunda izinto eziphilayo nezinqubo zokuphila. Ihlanganisa amagatsha ahlukahlukene, ngalinye ligxile esicini esithile sokuphila. Elinye lamagatsha ayisisekelo futhi abaluleke kakhulu i-biology yamaseli neyomzimba. Amaseli ayizingxenye ezincane kakhulu zokuphila ezikwazi ukwenza imisebenzi eyisisekelo yokuphila. … Funda kabanzi
Umphumela we-pH ekukhuleni kwezitshalo Isingeniso i-pH, noma "amandla e-Hydrogen," iyisilinganiso se-acidity noma i-alkalinity yesisombululo, esivezwa esikalini esingu-0 kuya ku-14. Lesi sikali sibalulekile emikhakheni ehlukahlukene yesayensi, okuhlanganisa nesayensi yezolimo. Kulesi sikali, inani elingu-7 libhekwa njengelingathathi hlangothi, amanani angaphansi kuka-7 ane-acidic, kanti amanani angaphezu kuka-7 ayisisekelo (i-alkaline). … Funda kabanzi
Isakhiwo kanye Nomsebenzi we-Endoplasmic Reticulum (ER) I-endoplasmic reticulum (ER) iyisici esibalulekile samaseli e-eukaryotic, edlala indima ebalulekile ezinqubweni ezahlukene zebhayoloji. Lesi sihloko sizochaza isakhiwo kanye nomsebenzi we-ER, sinikeze ukuqonda okuningiliziwe ngendima yayo ebalulekile empilweni yamaseli. I-ER iyisakhiwo esikhulu, esifana ne-labyrinth… Funda kabanzi
Izici Zezilwane Eziphila Ngokusebenzisa I-Ectothermic Isingeniso Izilwane eziphila ngokusebenzisa i-ectothermic, ezaziwa nangokuthi izilwane ezinegazi elibandayo, yizilwane ezithembele emithonjeni yokushisa yangaphandle ukulawula izinga lokushisa lomzimba wazo. Ngokungafani nezilwane eziphila ngokusebenzisa i-endothermic (ezinegazi elifudumele) njengezilwane ezincelisayo nezinyoni, ezingakhiqiza ukushisa kwangaphakathi ukuze zigcine izinga lokushisa lomzimba lihlala linjalo, izilwane eziphila ngokusebenzisa i-ectothermic azinalo lolu hlobo lomshini. Ngenxa yalokho, izinga lokushisa lomzimba wazo… Funda kabanzi
