Homology , hauv biology , zoo sib xws ntawm cov qauv, physiology, los yog kev loj hlob ntawm ntau hom kab mob raws li lawv qhovntsej thiaj tsis mob los ntawm ib tug evolutionary poj koob yawm txwv.
Cov lus nug tseem yog, peb txhais li cas hauv biology thaum peb siv lo lus homology?
Hauv biology , homology yog qhov zoo sib xws vim kev sib koom ua koob tsheej ntawm ib khub ntawm cov qauv, lossis cov noob, hauv cov se sib txawv. Evolutionary biology piav qhia homologous cov qauv yoog raws cov hom phiaj sib txawv raws li qhov tshwm sim ntawm qhovntsej thiaj tsis mob nrog kev hloov kho los ntawm ib tus poj koob yawm txwv.
Tsis tas li ntawd, ib qho piv txwv ntawm homology yog dab tsi? Homology saib qhov zoo sib xws uas muaj nyob rau hauv cov kab mob nyob rau hauv thiaj li yuav txiav txim siab ib yam koob hmoov. Qhov zoo sib xws tuaj yeem yog nyob rau hauv cov noob, cov tsos mob ntawm lub cev lossis kev ua haujlwm ntawm cov qauv. Piv txwv ntawm no suav nrog cov ceg ntawm cov noog, puav, tib neeg thiab lizards vim lawv muaj tib lub qauv.
Yog li ntawd, dab tsi yog qhov tseeb txhais ntawm homology?
Kev txhais ntawm homology . 1: qhov zoo sib xws feem ntau tshwm sim los ntawm cov hauv paus chiv keeb. 2a: zoo ib yam nyob rau hauv cov qauv ntawm qhov chaw ntawm cov kab mob sib txawv (xws li tis ntawm ib tug puav thiab tib neeg caj npab) vim evolutionary sib txawv los ntawm ib tug coj ib feem nyob rau hauv ib tug ntau yam poj koob yawm txwv - piv analogy.
Analogue txhais li cas hauv biology?
evolution. Alternative Title: zoo sib xws qauv. Analogy , hauv biology , zoo sib xws ntawm kev ua haujlwm thiab qhov zoo ib yam ntawm cov qauv uas muaj qhov sib txawv. Piv txwv li, tis ntawm ya, npauj, thiab ib tug noog yog analogous vim hais tias lawv tsim nws tus kheej raws li kev hloov mus rau ib qho kev ua haujlwm-ya.
Pom zoo:
Dab tsi yog qhov txhais ntawm lub hauv paus hauv biology?
Txhais. npe, plural: bases. (1) (molecular biology) Lub nucleobase ntawm nucleotide koom nrog hauv kev sib koom ua ke, xws li DNA lossis RNA polymer. (2) (anatomy) Qhov qis tshaj plaws los yog hauv qab ntawm cov nroj tsuag lossis tsiaj lub cev ze tshaj rau qhov txuas. (3) (chemistry) Ib qho dej-soluble compound uas reacts nrog acid thiab cov ntaub ntawv
Lub ntsiab lus ASE txhais li cas hauv biology?
Lub ntsiab lus '-ase' yog siv los qhia txog ib qho enzyme. Hauv enzyme naming, ib qho enzyme yog qhia los ntawm kev ntxiv -ase mus rau qhov kawg ntawm lub npe ntawm cov substrate uas cov enzyme ua. Nws kuj yog siv los txheeb xyuas cov chav kawm tshwj xeeb ntawm cov enzymes uas catalyze ib hom tshuaj tiv thaiv
Lub prefix stasis txhais li cas hauv biology?
Lub ntsiab lus (-stasis) hais txog kev muaj lub xeev ntawm kev sib npaug, kev ruaj ntseg lossis kev sib npaug. Nws kuj hais txog qhov qeeb lossis nres ntawm kev txav los yog kev ua si. Stasis kuj txhais tau tias qhov chaw lossis txoj haujlwm
Allele txhais li cas hauv biology?
Ib qho allele yog ib yam ntawm cov noob taum. Feem ntau cov noob muaj ob lub alleles, ib qho tseem ceeb allele thiab ib tug recessive allele. Yog hais tias lub cev yog heterozygous rau qhov zoo li ntawd, los yog muaj ib qho ntawm txhua tus allele, ces qhov tseem ceeb tshaj plaws yog qhia. Alleles yog thawj zaug txhais los ntawm Gregor Mendel hauv txoj cai ntawm kev cais
Homology txhais li cas?
Kev txhais ntawm homology. 1: qhov zoo sib xws feem ntau tshwm sim los ntawm cov hauv paus chiv keeb. 2a: zoo ib yam nyob rau hauv cov qauv ntawm qhov chaw ntawm cov kab mob sib txawv (xws li lub tis ntawm ib tug puav thiab tib neeg caj npab) vim evolutionary sib txawv los ntawm ib tug coj ib feem nyob rau hauv ib tug qub poj koob yawm txwv - piv analogy
