Hla mus yog cov txheej txheem uas homologous chromosomes pauv feem ntawm lawv cov kab ke. Nws yog tseem ceeb vim nws yog ib qhov chaw ntawm kev hloov ntawm caj ces.
Ib yam li ntawd, tib neeg nug, vim li cas kev hla dhau qhov tseem ceeb?
Kev hla dhau yog qhov tseem ceeb rau kev sib cais ntawm chromosomes thaum lub sij hawm meiosis. Hla mus kuj suav rau kev hloov pauv caj ces, vim yog kev sib pauv ntawm cov khoom siv caj ces thaum lub sijhawm hla dhau , cov chromatids tuav ua ke los ntawm centromere tsis zoo ib yam lawm.
Qhov thib ob, qhov tseem ceeb ntawm kev hla dhau quizlet yog dab tsi? Nws ua rau muaj qhov tshwm sim uas cov menyuam ntxhais muaj cov khoom siv caj ces sib txawv. Meiosis pib nrog ib lub cell, thiab xaus nrog _ cell.
Yog li ntawd, dab tsi yog hla dhau piav qhia?
Hla Hla Txhais. Hla mus yog kev sib pauv ntawm cov khoom siv noob caj noob ces ntawm cov tsis yog tus muam chromatids ntawm homologous chromosomes thaum lub sij hawm meiosis, uas ua rau cov allelic ua ke nyob rau hauv cov ntxhais cell. Cov khub ntawm chromosomes, txhua tus muab los ntawm ib leej niam leej txiv, hu ua homologous chromosomes.
Dab tsi yog qhov txiaj ntsig ntawm kev hla dhau?
A txiaj ntsig ntawm kev hla dhau yog tias nws tswj hwm kev sib txawv ntawm cov noob caj noob ces nyob rau hauv cov pej xeem, tso cai rau ntau lab tus kab mob sib txawv ntawm cov niam txiv mus rau cov xeeb ntxwv. Genetic variability yog qhov tseem ceeb heev rau kev muaj sia nyob mus ntev ntawm ib hom.

Txoj cai ntawm kev txuag huab hwm coj yog dab tsi thiab vim li cas nws tseem ceeb?
Txoj cai ntawm kev txuag ntawm huab hwm coj tseem ceeb heev rau kev kawm thiab tsim cov tshuaj tiv thaiv. Yog tias cov kws tshawb fawb paub txog qhov ntau thiab cov cim ntawm cov tshuaj reactants rau ib qho tshuaj tiv thaiv, lawv tuaj yeem kwv yees tus nqi ntawm cov khoom uas yuav ua
Kev cog qoob loo yog dab tsi thiab vim li cas nws tseem ceeb?
Los piav qhia yooj yim, "grounding" txhais tau hais tias txoj kev tsis tshua muaj hluav taws xob tau tsim rau hluav taws xob mus rau hauv av. Yog tias muaj hluav taws xob hluav taws xob lossis hluav taws xob luv luv thaum koj siv cov khoom siv, muaj lub hauv paus hauv av los hloov cov tam sim no rau hauv lub ntiaj teb yuav tiv thaiv koj ntawm hluav taws xob poob siab
Vim li cas nws tseem ceeb uas yuav tsum rov ua qhov kev sim thiab sim cov kev xav hauv ntau txoj kev?
Nws yog ib qho tseem ceeb rau cov kws tshawb fawb kom rov sim dua thaum ua qhov kev sim vim tias qhov kev txiav txim siab yuav tsum raug lees paub. Muaj tseeb vim tias cov txiaj ntsig ntawm txhua qhov kev xeem yuav tsum zoo sib xws. Lwm cov kws tshawb fawb yuav tsum tuaj yeem rov ua koj qhov kev sim thiab tau txais cov txiaj ntsig zoo sib xws. Tib txoj hauv kev los ntsuas qhov kev xav yog ua qhov kev sim
Kev xaiv permeability yog dab tsi thiab vim li cas nws tseem ceeb rau cov hlwb?
Selective permeability yog ib yam khoom ntawm cellular daim nyias nyias uas tsuas tso cai rau tej molecules nkag los yog tawm ntawm lub cell. Qhov no yog qhov tseem ceeb rau lub xov tooj ntawm tes kom tswj hwm nws cov kev txiav txim sab hauv tsis hais txog kev hloov pauv rau ib puag ncig
ATP yog dab tsi thiab vim li cas nws tseem ceeb rau kev ua pa ntawm tes?
ATP muaj ib pawg phosphate, ribose thiab adenine. Nws lub luag haujlwm hauv kev ua pa ntawm tes yog qhov tseem ceeb vim nws yog lub zog txiaj ntawm lub neej. Lub synthesis ntawm ATP absorbs zog vim ntau ATP yog tsim tom qab
