Vertebrates tau hloov kho vertebrae thiab tav nyob rau hauv ntau txoj kev; Cov vertebra tseem ceeb tau rov hais dua thiab hloov mus rau ntau hom pob txha: sacral, lumbar, thoracic, thiab ncauj tsev menyuam. Txawm li cas los xij, tej zaum ib qho piv txwv zoo tshaj plaws ntawm serial homology tuaj yeem pom nyob rau hauv lub cev tsim ntawm hom cray-fish.
Ib qho piv txwv ntawm homology yog dab tsi?
Muaj serial homology, piv txwv li, nruab nrab ntawm caj npab thiab txhais ceg ntawm tib neeg, nruab nrab ntawm xya lub ncauj tsev menyuam ntawm cov tsiaj nyeg, thiab nruab nrab ntawm cov ceg lossis nplooj ntoo. Cov kab ke sib koom ua ke ntawm arthropods yog cov piv txwv zoo ntawm serial homology.

Serial homology yog kev hloov pauv ntawm cov kabmob sib xws kom muaj cov haujlwm sib txawv.
3 yam piv txwv ntawm homologous qauv yog dab tsi?
Ib qho piv txwv ntawm homologous qauv yog lub forelimbs ntawm vertebrates, qhov twg tis ntawm puav thiab noog, caj npab ntawm primates, pem hauv ntej flippers ntawm whales thiab forelegs ntawm plaub -leggedvertebrates zoo li dev thiab khej yog tag nrho muab los ntawm tib yam poj koob yawm txwv tetrapod qauv.

Thaum twg qhov kev rov tshwm sim tshwm sim?
Thaum Replevin tuaj yeem thov Li no, qhov no yog qhov xwm txheej tshwm sim ntau tshaj plaws uas yuav tshwm sim thaum tus neeg siv khoom tsis raug them nyiaj qiv tsheb. Kev ua txhaum cai ntawm kev thaj yeeb nyab xeeb yog me ntsis luv luv. Nws tsis suav nrog kev txeeb tsheb yam tsis tau ceeb toom lossis kub xov tooj kom tsav tsheb mus.
Thaum qhov no yog qhov tshwm sim uas tshwm sim?
Lub hauv paus ntsiab lus ntawm kev mob Nrog qhov tshwm sim (uppada) ntawm qhov no, qhov tshwm sim. Thaum tsis muaj qhov no, qhov ntawd tsis tuaj.

Yuav ua li cas txiav txim siab seb qhov kev tshwm sim yog tshwm sim los yog tsis ua raws li txoj cai?
Kev sib xyaw ua lej ntawm kev hloov pauv enthalpy thiab hloov pauv hloov pauv tso cai rau kev hloov pauv ntawm lub zog dawb los suav. A tawm tsam nrog tus nqi tsis zoo rau ΔG tso tawm lub zog dawb thiab yog li nws tus kheej. Cov tshuaj tiv thaiv nrog qhov zoo ΔG yog tsis ua raws li kev xav thiab yuav tsis nyiam cov khoom.
