Ubuchwepheshe be-Forensic Biology ekuPhenyweni koBugebengu Umkhakha wobuchwepheshe be-forensic biology usubaluleke kakhulu ohlelweni lwesimanje lobulungiswa bobugebengu. Lo mkhakha wesayensi okhethekile uhlinzeka ngamathuluzi nezindlela ezibalulekile ezisiza ekuxazululeni ubugebengu ngokuhlaziya ubufakazi bezinto eziphilayo. Ukuhlanganiswa kwalawa ma-technologies ayinkimbinkimbi kushintshe uphenyo lwendawo yobugebengu, okuholele ekunembeni okuphezulu ku… Funda kabanzi

Umsebenzi kanye Nesakhiwo Sezicubu Ze-Meristem Ezitshalweni Izicubu ze-Meristem ezitshalweni ziyisisekelo ekukhuleni nasekuthuthukisweni kwezitshalo, zisebenza njengendawo yokugcina amaseli angahlukanisiwe, ahlukanisa ngenkuthalo. Lawa maseli anamandla okuhlukana abe izinhlobo ezahlukene zamaseli ezikhethekile, anegalelo ekwakhekeni kwezitho nezakhiwo zesitshalo. Ukuqonda umsebenzi kanye nesakhiwo... Funda kabanzi

Izindlela Zokumelana Namagciwane Kuma-bacteria Abangela Izifo Ama-antibiotic sekuyisikhathi eside emenyezelwa njengemithi eyisimangaliso, eguqula imithi yesimanje futhi esindisa izimpilo ezingenakubalwa. Kodwa-ke, ukusebenza kahle kwale mithi kuya ngokuya kuncipha ngenxa yokwanda kokumelana namagciwane kumabhaktheriya abangela izifo. Izindlela amabhaktheriya afinyelela ngazo lokhu kumelana zinezinhlangothi eziningi futhi ziletha inselele enkulu … Funda kabanzi

Isihloko: Umthelela Wemisebe Esakhiweni Nasemsebenzini we-DNA Isingeniso: I-Deoxyribonucleic acid (i-DNA) iyi-molecule plan ebhala ulwazi lwezakhi zofuzo oludingekayo ekuthuthukisweni, ekusebenzeni nasekuzalweni kwazo zonke izinto eziphilayo. Ukugcina ubuqotho be-DNA kubalulekile ekusebenzeni kahle kwamaseli, futhi noma yikuphi ukulimala kwale molekyuli eyinkimbinkimbi kungaholela ezinhlobonhlobo … Funda kabanzi

Izici Ezithinta Ukuhluma Kwembewu Ukuhluma kwembewu kuyisigaba esibalulekile emjikelezweni wokuphila kwezitshalo, okumelela ibhuloho phakathi kwezigaba zokuzala kanye nezokutshala. Kuhilela ukusebenza kwemishini ye-metabolic yembewu, okuphetha ngokuvela kwe-radicle (impande ye-embryonic) kanye ne-plumule (ihlumela). Le nqubo ebucayi ithonywa izinhlobo ezahlukene … Funda kabanzi

I-Nanoscale Biology: Ubuchwepheshe kanye Nezicelo Isingeniso I-Nanoscale biology imelela umngcele othakazelisayo ocwaningweni lwesayensi kanye nokusungula izinto ezintsha kwezobuchwepheshe. Enhliziyweni yalo mkhakha ukutadisha kanye nokuphathwa kwezinqubo zezinto eziphilayo esikalini se-nanometer (ingxenye eyodwa kweziyizigidigidi zemitha). Ngokusebenza kulesi sikali, ososayensi nonjiniyela bangahlola futhi basebenzise okuhlukile… Funda kabanzi

Isakhiwo kanye Nomsebenzi Wesistimu Yokuzivikela Yomuntu Umzimba womuntu uyisimiso esiyinkimbinkimbi kakhulu sezitho zomzimba, izicubu, namaseli asebenzisana ngokuvumelana ukuze alondoloze impilo. Phakathi kwalokhu, isimiso somzimba sokuzivikela sivelele njengendlela ebalulekile, esisebenza njengenethiwekhi yokuzivikela yomzimba ezifweni ezibangelwa amagciwane, okuhlanganisa amagciwane, amabhaktheriya, isikhunta, kanye nezinambuzane. Ukuqonda isakhiwo... Funda kabanzi

Umsebenzi we-Chloroplast njengeSikhungo se-Photosynthesis ezitshalweni Ama-chloroplast, ama-organelle akhethekile kakhulu ahlukile kumaseli ezitshalo kanye nolwelwe oluthile, abalulekile enkambisweni ye-photosynthesis, lapho amandla okukhanya aguqulwa khona abe amandla amakhemikhali ukuze akhuthaze imisebenzi yezinto eziphilayo. Lo msebenzi oyinkimbinkimbi nobalulekile usungula ama-chloroplast njengezingxenye ezibalulekile zokusekela … Funda kabanzi

Indima Yebhayoloji Yamaseli Ekuthuthukisweni Kwemithi Emisha Ibhayoloji yamaseli yisifundo sesayensi esihlola isakhiwo, umsebenzi, kanye nokuziphatha kwamaseli. Njengamayunithi ayisisekelo okuphila, amaseli aphakathi kwezinqubo zezinto eziphilayo, kusukela ku-physiology eyisisekelo kuya ezindleleni ezibangela izifo. Ukuqonda i-biology yamaseli kubalulekile ekuthuthukiseni okusha... Funda kabanzi
