Mitosis : Hauv Summary
Hauv prophase , cov nucleolus ploj mus thiab chromosomes condense thiab pom. Hauv kev anaphase , tus muam chromatids (tam sim no hu ua chromosomes) raug rub mus rau cov ncej. Hauv telophase , chromosomes tuaj txog ntawm cov ncej, thiab cov khoom siv lub hnab ntawv nuclear nyob ib puag ncig txhua pawg chromosomes.
Tsis tas li ntawd, muaj dab tsi tshwm sim hauv prophase?
Prophase yog thawj theem ntawm mitosis, tshwm sim tom qab xaus ntawm G2 ib feem ntawm interphase. Thaum prophase , niam txiv ntawm tes chromosomes - uas tau duplicated thaum lub sij hawm S theem - condense thiab ua ntau txhiab lub sij hawm ntau compact tshaj lawv nyob rau hauv interphase.
Tom qab ntawd, lo lus nug yog, dab tsi tshwm sim thaum lub sij hawm 4 theem ntawm mitosis? Mitosis yog tus txheej txheem uas lub nucleus ntawm ib tug eukaryotic cell faib. Thaum Cov txheej txheem no, tus muam chromatids cais ntawm ib leeg thiab txav mus rau cov ncej ntawm tes. Qhov no tshwm sim hauv plaub theem , hu ua prophase, metaphase, anaphase, thiab telophase.
Hauv qhov no, yuav ua li cas tshwm sim hauv telophase theem ntawm mitosis?
Telophase yog technically qhov kawg theem ntawm mitosis . Nws lub npe muab los ntawm lo lus Latin telos uas txhais tau tias kawg. Lub sijhawm no theem , tus muam chromatids ncav cuag tus ncej. Cov vesicles me me hauv lub cell pib rov tsim nyob ib ncig ntawm pawg chromosomes ntawm txhua qhov kawg.
Yuav ua li cas tshwm sim hauv prophase yooj yim?
Cov khoom siv caj ces yog duplicated thaum lub sij hawm interphase ntawm lub cell. Thaum ib lub xovtooj tau txais lub teeb liab tias nws yog duplicate, nws yuav nkag mus rau thawj lub xeev ntawm mob mitosis hu ua " prophase ". Prophase - Thaum lub sij hawm no, chromatin condenses mus rau hauv chromosomes thiab nuclear membrane thiab nucleolus tawg.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Yuav ua li cas tshwm sim hauv qhov kev sim Golden Rain?
Cov tshuaj tiv thaiv los nag kub ua rau pom kev tsim cov khoom precipitate. Kev sim los nag kub muaj ob lub ntsiab lus ionic soluble, potassium iodide (KI) thiab lead(II) nitrate (Pb(NO3)2). Lawv pib yaj nyob rau hauv cov dej sib cais, uas yog txhua yam tsis muaj xim
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Yuav ua li cas tshwm sim tib lub sijhawm li telophase 2?
Thaum lub sij hawm telophase II, theem plaub ntawm meiosis II, cov chromosomes ncav cuag tus ncej, cytokinesis tshwm sim, ob lub hlwb tsim los ntawm meiosis kuv faib ua plaub haploid ntxhais hlwb, thiab lub hnab ntawv nuclear (dawb nyob rau hauv daim duab ntawm txoj cai) daim ntawv
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
