Isihloko: Imibuzo Eyisibonelo Exoxa Ngombono Wokuziphendukela Kwezamakhemikhali Isingeniso Umbono wokuziphendukela kwezamakhemikhali uyisisekelo esibalulekile sokuqonda imvelaphi yokuphila eMhlabeni. Lo mbono uphenya ukuthi ama-molecule ayisisekelo akhona eMhlabeni wasendulo angaguquka kanjani abe izakhiwo eziyinkimbinkimbi futhi ekugcineni akhe izinto eziphilayo. Ukuqonda lo mbono kubalulekile nasekuphenduleni imibuzo mayelana... Funda kabanzi

Okulandelayo yisihloko esithi "Imibuzo Yengxoxo Eyisibonelo Ngombono Wokuziphendukela Kwemvelo Wangaphambi KukaDarwin": — Imibuzo Yengxoxo Eyisibonelo Ngombono Wokuziphendukela Kwemvelo Wangaphambi KukaDarwin Ngaphambi kokuba uCharles Darwin ashicilele umbono wakhe wokuziphendukela kwemvelo encwadini yakhe ethi, "On the Origin of Species" ngo-1859, imibono ehlukahlukene mayelana noshintsho kanye nemvelaphi yokuphila yayisivele ikhona. Umbono wokuziphendukela kwemvelo wangaphambi kukaDarwin uchaza imibono kanye nemibono mayelana nokuziphendukela kwemvelo ngaphambi komcabango... Funda kabanzi

Imibuzo Eyisibonelo Exoxa Ngokuthuthuka Kwethiyori Yokuziphendukela Kwemvelo Isingeniso Ithiyori yokuziphendukela kwemvelo ingenye yethiyori yesayensi ebaluleke kakhulu ekuqondeni imvelaphi kanye nokuthuthukiswa kokuphila eMhlabeni. Kusukela yethulwa nguCharles Darwin ngekhulu le-19, le thiyori iye yathuthuka futhi yathuthukiswa ngezindlela ezahlukene. Kulesi sihloko, sizoxoxa ngemibuzo eyisibonelo kanye nezingxoxo ezihlobene nokuthuthukiswa... Funda kabanzi

Isibonelo Sombuzo Wokuxoxisana: Incazelo Yokuziphendukela Kwemvelo. Ukuziphendukela kwemvelo umqondo oyisisekelo ku-biology onikeza incazelo ejulile ngezinhlobo zezinto eziphilayo zoMhlaba. Nakuba ngokuvamile kuyisihloko sengxoxo nempikiswano, ukuqonda ukuziphendukela kwemvelo kubalulekile kunoma ubani ofisa ukuqhubeka nezifundo zakhe ze-biology. Lesi sihloko sihlose ukunikeza ukuqonda okungcono ngengxoxo... Funda kabanzi

Izinkinga Zesampula Ukuxoxa Ngezinguquko Zezakhi Zofuzo Nezifo Ezizuzwayo Ukuguquka kwezakhi zofuzo nezifo ezizuzwayo kuyizihloko ezimbili ezibalulekile, ezihlobene nezakhi zofuzo. Zombili zinikeza ukuqonda kokuthi ifa lezakhi zofuzo lingathinta kanjani impilo yabantu kanye nabantu bonke. Kulesi sihloko, sizoxoxa ngezinkinga eziningana zesampula ezigxile ekuguqulweni kwezakhi zofuzo nezifo ezizuzwayo, kanye nengxoxo yazo… Funda kabanzi

Isihloko: Izibonelo Zezinkinga Zokuxoxa Ngokunquma Ubulili Ukunquma ubulili ezintweni eziphilayo kuyisihloko esithakazelisayo ku-biology kanye nezakhi zofuzo. Ukuqonda le ndlela akubalulekile nje kuphela ezimweni zemfundo kodwa futhi kunezinzuzo kwezolimo, ukufuya izilwane, ngisho nakwezokwelapha. Lesi sihloko sizochaza eminye imiqondo eyisisekelo ehlobene nokunquma ubulili… Funda kabanzi

Izinkinga Zesethi Ehambisanayo: Izinkinga Zesibonelo Isingeniso Izifundo zezibalo zivame ukufaka izingxoxo mayelana namasethi kanye nokusebenza kwawo, okunye kwawo ukuhambisana. Ukuqonda kahle lo mqondo kungasiza abafundi ukuxazulula izinkinga ezahlukahlukene ezihlobene namasethi kalula. Kulesi sihloko, sizoxoxa ngezibonelo eziningana zezinkinga zesethi ehambisanayo kanye nezingxoxo ukuze abafundi bakwazi kangcono... Funda kabanzi

Imibuzo Nengxoxo Yesibonelo se-Epistasis kanye ne-Hypostasis Ukufunda izakhi zofuzo kudinga ukuqonda okuhle kokuxhumana phakathi kwezakhi zofuzo nokuthi lokhu kuthonya kanjani i-phenotype yesidalwa. Imiqondo emibili ebalulekile futhi exoxwa njalo kuzakhi zofuzo yi-epistasis kanye ne-hypostasis. Lesi sihloko sizochaza le mibono emibili ngokunikeza imibuzo nezingxoxo zesibonelo ku… Funda kabanzi

Imibuzo Nengxoxo Yesibonelo Se-Polymer I. Isingeniso Ama-polymer ayizinhlanganisela zamakhemikhali ezinezakhiwo ezinkulu zama-molecule ezakhiwe ngamayunithi amancane aphindaphindayo abizwa ngokuthi ama-monomers. Ama-polymer angatholakala ngezindlela ezahlukene futhi asetshenziswa ezicini eziningi zokuphila kwansuku zonke, kusukela kumapulasitiki nerabha kuya kumaprotheni ne-DNA emzimbeni womuntu. Kulesi sihloko, si… Funda kabanzi

Imibuzo Nengxoxo Ngesibonelo Se-Cryptomery I-Cryptomery iyinto yofuzo lapho i-gene ingabonisi ngqo imiphumela yayo kodwa kunalokho idinga ukuba khona kwezinye izakhi zofuzo ukuze ibonise uhlobo lwayo. Leli gama laqanjwa okokuqala yisazi sezakhi zofuzo saseJalimane u-Erich von Tschermak, owaphawula ukuthi ezinye izici zezitshalo zivela kuphela uma kukhona ukuxhumana okuthile phakathi kwezakhi zofuzo ezithile. Isingeniso ku-Cryptomery… Funda kabanzi
