Biologists siv lo lus kev qoj ib ce los piav txog qhov zoo npaum li cas ib qho genotype yog tawm ntawm cov xeeb ntxwv nyob rau tiam tom ntej txheeb ze rau qhov zoo li cas lwm cov genotypes ntawm nws. Ib genotype kev qoj ib ce suav nrog nws lub peev xwm kom muaj sia nyob, nrhiav tus khub, tsim cov xeeb ntxwv - thiab thaum kawg tso nws cov noob rau tiam tom ntej.
Tsis tas li ntawd, dab tsi yog txhais los ntawm evolutionary Fitness?
Evolutionary Fitness yog qhov zoo npaum li cas ib hom muaj peev xwm rov tsim dua hauv nws ib puag ncig. Nyob rau hauv lawv ib puag ncig lawv tau zoo heev thaum lawv noj, rov tsim dua, thiab txuas ntxiv rau lawv hom. Tab sis dab tsi feem ntau nres evolutionary qoj , thiab koj tus tsiaj T. rex, yog kev hloov hauv ib puag ncig.
Ib yam li ntawd, qhov twg yog qhov zoo tshaj plaws txhais ntawm kev qoj ib ce?

Artificial xaiv zoo li tej yam ntuj tso xaiv nyob rau hauv uas nws ua rau evolution; txawm li cas los xij nws txawv vim tib neeg yog ncaj qha xaiv cov kab mob uas tsim tawm.
Yog li ntawd, dab tsi yog qhov ntsuas ntawm evolutionary Fitness?
Lub ntsiab lus tseem ceeb ntawm kev xaiv ntuj yog qhov evolutionary qoj ntawm lub cev. Kev qoj ib ce yog ntsuas los ntawm lub cev muaj peev xwm muaj sia nyob thiab yug me nyuam, uas txiav txim siab qhov loj ntawm nws cov caj ces pab rau tiam tom ntej. Cov cwj pwm no tau hais tias "xaiv rau".
Dab tsi yog qhov tseeb txhais ntawm kev qoj ib ce nyob rau hauv cov nqe lus ntawm evolutionary kev vam meej quizlet?
Txoj cai txhais ntawm "fitness "hauv evolutionary biology. - hais txog kev yug me nyuam kev vam meej txheeb ze rau lwm tus neeg hauv cov pejxeem. -Implies ib yam dab tsi zoo matched los yog haum rau nws ib puag ncig. - qhia txog lub xeev ntawm kev noj qab haus huv zoo vim yog kev tawm dag zog lossis khoom noj khoom haus.

Nyob rau hauv lawv ib puag ncig lawv tau zoo heev thaum lawv noj, rov tsim dua, thiab txuas ntxiv rau lawv hom. Tab sis dab tsi feem ntau nres evolutionary zog, thiab koj tus tsiaj T. rex, yog ib qho kev hloov ntawm ib puag ncig
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
