Interphase yog lub sijhawm rau lub cell los npaj rau meiosis thiab ib feem ntawm qhov kev npaj no suav nrog kev nce ob npaug ntawm cov chromosomes hauv lub cell muaj. Qhov no ib feem ntawm interphase yog hu ua S theem, nrog rau S sawv rau synthesis. Txhua chromosome xaus nrog ib tus ntxaib zoo tib yam hu ua tus muam chromatids.
Ib yam li ntawd, tib neeg nug, dab tsi tshwm sim hauv interphase 1 ntawm meiosis?
Chromosomes pom, hla dhau tshwm sim, cov nucleolus ploj, cov meiotic spindle cov ntaub ntawv, thiab lub hnab ntawv nuclear ploj mus. Thaum pib ntawm prophase Kuv, cov chromosomes twb duplicated. Thaum prophase Kuv, lawv coil thiab ua luv luv thiab thicker thiab pom nyob rau hauv lub teeb microscope.
Tsis tas li ntawd, puas muaj meiosis muaj kev cuam tshuam? Interphase . Muaj ob theem lossis theem ntawm meiosis : meiosis kuv thiab meiosis II. Ua ntej ib tug faib cell nkag meiosis , nws undergoes lub sij hawm ntawm kev loj hlob hu ua interphase . Nyob rau theem no, lub cell nce hauv huab hwm coj hauv kev npaj rau kev faib cell.
Tom qab ntawd, lo lus nug yog, dab tsi tshwm sim loj tshwm sim thaum interphase hauv meiosis?
Piv txwv li, ua ntej yuav mob meiosis, lub xovtooj ntawm tes mus dhau lub sijhawm cuam tshuam uas nws loj hlob, rov ua dua nws cov chromosomes, thiab xyuas tag nrho nws cov tshuab kom paub meej tias nws npaj txhij los faib. Zoo li mitosis, meiosis kuj muaj cov theem sib txawv hu ua prophase, metaphase, anaphase , thiab telophase.
Yuav ua li cas tshwm sim nyob rau hauv txhua theem ntawm interphase?
Peb theem ntawm interphase npe G1, S, thiab G2. Thaum lub sij hawm interphase , lub cell loj hlob thiab cov nucleus DNA yog duplicated. Interphase yog ua raws li mitotic theem . Thaum cov mitotic theem , cov duplicated chromosomes yog segregated thiab faib mus rau hauv tus ntxhais nuclei.

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
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 thaum interphase hais txog DNA uas tseem ceeb rau kev faib cell?
Thaum lub sij hawm interphase, ib lub xov tooj ntawm tes nce loj, synthesis tshiab proteins thiab organelles, replicates nws chromosomes, thiab npaj rau cell faib los ntawm kev tsim spindle proteins. Ua ntej ntawm tes faib, chromosomes yog replicated, kom txhua chromosome muaj ob zoo tib yam 'viv ncaus' chromatids
Yuav ua li cas tshwm sim thaum ib tug tam sim no nqa coil muab tso rau hauv ib tug magnetic teb?
Yog tias tus neeg nqa khoom nqa tam sim no tau muab tso rau hauv qhov chaw sib nqus, nws ntsib lub zog Lorentz (tshwj tsis yog lub kaum sab xis ntawm qhov ntws ntawm tam sim no thiab cov kab hlau nplaum yog 0 °)
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
