A nyob sib txawv yog qhov koj ntsuas hauv qhov kev sim thiab dab tsi cuam tshuam thaum lub sijhawm sim. Cov nyob sib txawv teb rau cov ywj pheej variable . Nws yog hu ua nyob vim nws "depends" ntawm tus ywj pheej variable.
Ib yam li ntawd, nws raug nug, qhov ntsuas qhov sib txawv yog dab tsi?
1 Kev txhais Lub cev muaj nuj nqis, khoom, lossis cov xwm txheej uas yuav tsum muaj ntsuas . Feem ntau ntsuas qhov sib txawv yog qhov kub thiab txias, siab, tus nqi ntws, thickness, ceev, thiab lwm yam. 2. Lub lauj kaub ntawm cov txheej txheem uas tau saib xyuas los txiav txim qhov tseeb ntawm qhov kev tswj sib txawv.
Dab tsi yog qhov sib txawv hauv kev tshawb nrhiav kev sim? A sib txawv yog txhua yam uas hloov tau lossis hloov tau. Hauv lwm lo lus, nws yog ib qho tseem ceeb uas tuaj yeem tswj tau, tswj tau, lossis ntsuas hauv ib qho kev sim . Koj qhov kev xav yog qhov no sib txawv ua rau muaj kev cuam tshuam ncaj qha rau tus neeg nyob sib txawv.
Tsis tas li ntawd, yuav ntsuas qhov hloov pauv li cas?
Cov nyob sib txawv yog cov sib txawv uas yog ntsuas los yog sim nyob rau hauv ib qho kev sim. Piv txwv li, nyob rau hauv ib txoj kev tshawb nrhiav seb qhov kev qhia qhia cuam tshuam li cas rau cov qhab nia xeem, cov dependent variable yuav yog cov neeg koom nrog cov qhab nia xeem, vim qhov ntawd yog qhov ua tau ntsuas.
Dab tsi ntawm qhov sib txawv yog feem pua?
Nominal sib txawv feem ntau summarized li proportions los yog feem pua . Piv txwv li, yog tias koj suav cov txiv neej thiab poj niam A.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov twg yog qhov tseeb dua qhov hloov pauv pipette lossis ntsuas pipette?
Kawm tiav pipettes yog tsawg dua li volumetric pipettes. Mohr kawm tiav pipettes, uas yog qee zaum hu ua "drain out pipettes", tau cim nrog xoom thaum pib ntawm lawv qhov kawg conical, thaum Serological kawm tiav pipettes, tseem hu ua "tsov tawm pipettes", tsis txhob tso cov cim xoom

Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Peb qhov laj thawj tseem ceeb ntawm kev hloov pauv hloov pauv yog dab tsi?
Allele frequencies nyob rau hauv ib tug pej xeem yuav hloov vim plaub lub hauv paus zog ntawm evolution: Natural Selection, Genetic Drift, Mutations thiab Gene Flow. Kev hloov pauv yog qhov kawg ntawm cov alleles tshiab hauv cov noob caj noob ces. Ob ntawm cov txheej txheem tseem ceeb tshaj plaws ntawm kev hloov pauv hloov pauv yog: Natural Selection thiab Genetic Drift
