Ua ntej cov chromosomes sib npaug tuaj yeem sib cais thiab faib sib npaug rau ob tus ntxhais lub hlwb thaum lub sijhawm mitosis, txawm li cas los xij, lawv yuav tsum tau teeb tsa kom tsim nyog, thiab cov txheej txheem no pib hauv S theem.
Yuav ua li cas cov ntxhais cell muaj tib tus lej ntawm chromosomes tom qab mitosis?
Mitosis tsim ob tus ntxhais zoo tib yam uas txhua tus muaj tib tus lej ntawm chromosomes li lawv niam lawv txiv. Hauv qhov sib piv, meiosis ua rau muaj plaub tus ntxhais tshwj xeeb, txhua tus muaj ib nrab ntawm cov chromosomes raws li niam txiv cell.
Pob cov hlwb puas muaj ib nrab chromosomes?
Txhua tus ntxhais ntawm tes yog haploid thiab tsuas muaj ib pawg chromosomes, lossis ib nrab ntawm tag nrho cov chromosomes ntawm thawj cell. Meiosis II yog ib qho mitotic faib ntawm txhua lub hlwb haploid uas tsim hauv meiosis I.
Yuav ua li cas yog cov ntxhais cell tsis zoo ib yam?
Yog hais tias cov chromosomes faib tsis sib npaug thaum lub sij hawm mitosis, ib tug ntxhais cell yuav muaj trisomy, txhais tau hais tias nws muaj peb daim ntawv ntawm ib tug chromosomes es tsis txhob ntawm ib txwm ob, thiab cov lwm tus yuav tsis muaj chromosome. Lub sij hawm dav dav rau qhov tsis sib npaug ntawm tus lej chromosome yog aneuploidy.
Puas muaj pes tsawg chromosomes txhua tus ntxhais cell muaj?
Thaum kawg ntawm mitosis, ob tug ntxhais cell yuav yog cov ntawv luam ntawm tus thawj cell. Txhuantxhais cell yuav muaj 30 chromosomes.

Puas muaj qhov sib npaug sib npaug?
Ib kab kab sib npaug feem ntau muaj ib qho kev daws teeb meem, tab sis qee zaum nws tsis tuaj yeem muaj kev daws teeb meem (kab kab sib txuas) lossis kev daws tsis kawg (ib kab). Kab lus no tshuaj xyuas tag nrho peb qhov xwm txheej. Ib qho kev daws teeb meem.
In poisson faib txhais tau tias sib npaug rau qhov sib txawv?
Qhov nruab nrab thiab qhov sib txawv ntawm Poisson kev faib tawm yog tib yam, uas yog sib npaug rau qhov nruab nrab ntawm kev ua tiav uas tshwm sim hauv lub sijhawm muabntawm lub sijhawm. Vim li cas lub ntsiab lus thiab qhov sib txawv yog tib yam hauv Poisson kev faib tawm?
Thaum lub sijhawm ntsuas qhov sib npaug ntawm qhov ntsuas cua sov yog nyob rau hauv kev sib cais?
Los ntawm txoj cai thib ob ntawm thermodynamics: Txoj cai thib ob ntawm thermodynamics hais tias qhov entropy ntawm ib qho cais qhov system yeej tsis txo qis, vim tias cov tshuab cais ib txwm hloov mus rau qhov sib npaug ntawm qhov ntsuas kub, lub xeev nrog siab kawg entropy.
Puas yog txhua qhov sib npaug sib npaug?
Yog, tag nrho peb tiam ntawm daim ntawv dawb tau raws nraim qhov loj me nrog tib lub pob layout. Siv tau rau rooj plaub raws li cov ntaub ntawv paperwhite haum rau txhua daim ntawv dawb, yav dhau los thiab tam sim no. Qhov ntsuas 6 nti yog hais txog qhov loj me ntawm lub vijtsam nkaus xwb, ntsuas ntawm kab pheeb ces kaum ntawm ib ces kaum mus rau lub kaum sab xis.
Dab tsi yog qhov sib npaug sib npaug?
Revolving credit yog hom credit uas tsis muaj tus lej them nyiaj tas li, sib piv rau cov credit qiv. Cov npav rho nyiaj yog ib qho piv txwv ntawm kev siv cov credit siv los ntawm cov neeg siv khoom. Cov tuam txhab qiv nyiaj rov qab feem ntau yog siv los muab cov nyiaj tau los rau lub tuam txhab kev ua haujlwm txhua hnub.
