Thaum 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 lub hlwb haploid ntxhais, thiab lub hnab ntawv nuclear (dawb hauv daim duab ntawm txoj cai) daim ntawv.
Ntawm no, muaj pes tsawg chromosomes tom qab telophase 2?
1 Teb. Hauv tib neeg, muaj 23 chromosomes hauv telophase II, tus naj npawb haploid, n, rau tib neeg. Hauv anaphase II, tus viv ncaus chromatids tam sim no thaum kawg ntawm meiosis kuv tau muab cais ua 23 tus neeg chromosomes.
Tsis tas li ntawd, vim li cas telophase 2 tseem ceeb? Ib lub hnab ntawv nuclear tsim nyob ib ncig ntawm txhua pawg chromosomes. Cytokinesis tshwm sim, tsim plaub tus ntxhais hlwb (gametes, hauv cov tsiaj), txhua tus nrog cov chromosomes haploid. Vim tias hla dhau, qee cov chromosomes tau pom tias muaj cov ntu ntawm cov niam txiv chromosomes qub.
Hais txog qhov no, ua li cas thaum lub sij hawm telophase?
Telophase yog technically theem kawg ntawm mitosis. Nws lub npe muab los ntawm lo lus Latin telos uas txhais tau tias kawg. Thaum theem no, 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 thaum lub sij hawm telophase II ntawm meiosis quizlet?
Nuclear membrane pib tsim nyob ib ncig ntawm haploid pawg ntawm chromosomes.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Yuav ua li cas tshwm sim hauv prophase metaphase anaphase telophase?
Mitosis: Hauv Cov ntsiab lus hauv prophase, cov nucleolus ploj mus thiab chromosomes condense thiab pom. Hauv anaphase, tus muam chromatids (tam sim no hu ua chromosomes) raug rub mus rau cov ncej sib txawv. Hauv telophase, chromosomes tuaj txog ntawm cov ncej, thiab cov khoom siv lub hnab ntawv nuclear nyob ib puag ncig txhua pawg chromosomes
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 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
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
