Cov Cov xwm txheej tseem ceeb ntawm telophase suav nrog kev rov tshwm sim thiab nthuav dav ntawm nucleolus, kev loj hlob ntawm tus ntxhais nuclei rau lawv qhov loj me me, decondensation ntawm chromatin uas ua rau lub ntsej muag ci dua ntawm cov nuclei nrog theem-qhov sib txawv optics, thiab lub sijhawm nrawm, postmitotic nuclear migration thaum lub sijhawm
Tsuas yog li ntawd, 4 yam uas tshwm sim thaum lub sij hawm telophase yog dab tsi?
Telophase . Thaum lub sij hawm telophase , cov chromosomes pib uncoil thiab tsim chromatin. Qhov no npaj cov khoom siv caj ces rau tswj cov kev ua haujlwm metabolic ntawm cov hlwb tshiab. Lub spindle kuj tawg, thiab cov ntaub ntawv tshiab nuclear (nuclear hnab ntawv) daim ntawv.
Qhov thib ob, vim li cas telophase tseem ceeb? Cell faib yog ib qho tsis tshua muaj tseem ceeb ib feem ntawm txoj kev loj hlob ntawm tag nrho cov hlwb ntawm tag nrho cov kab mob, nrog rau tib neeg, tsiaj txhu thiab nroj tsuag. Telophase yog theem kawg ntawm kev faib cell ua ntej cytokinesis tshwm sim los faib cov hlwb rau hauv cov menyuam ntxhais.
Yog li ntawd, dab tsi yog txheej txheem ntawm telophase?
Telophase yog theem tsib thiab zaum kawg ntawm mob mitosis , cov txheej txheem uas cais cov noob caj noob ces duplicated nqa nyob rau hauv lub nucleus ntawm niam txiv cell mus rau hauv ob zoo tib yam ntxhais cell. Telophase pib thaum lub replicated, khub chromosomes tau sib cais thiab rub mus rau opposite sab, los yog ncej, ntawm tes.
Dab tsi yog cov xwm txheej tseem ceeb ntawm metaphase?
Metaphase . Chromosomes kab nyob rau hauv metaphase phaj, nyob rau hauv nro los ntawm mitotic spindle. Ob tug viv ncaus chromatids ntawm txhua tus chromosome raug ntes los ntawm microtubules los ntawm cov ncej spindle. Hauv metaphase , lub spindle tau ntes tag nrho cov chromosomes thiab lined lawv nyob rau hauv nruab nrab ntawm lub cell, npaj txhij los faib.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog cov peev txheej tseem ceeb ntawm California?
California yog nplua nuj nyob rau hauv natural resources. Huab cua, dej, nroj tsuag, thiab tsiaj txhu yog natural resources. Yog li ntawd yog ntsev, thee, thiab roj
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Dab tsi yog qhov txawv ntawm cov khoom tseem ceeb thiab cov kab hauv cov dej hiav txwv?
Ib cag ntawm 12 lub ntsiab lus uas yog cov ntsiab lus tseem ceeb lossis cov ntsiab lus me thiab qee cov ntsiab lus uas yog cov roj yaj, tag nrho lwm cov ntsiab lus yaj hauv dej hiav txwv muaj nyob rau hauv cov ntsiab lus tsawg dua 1 ppm thiab hu ua cov kab hauv qab. Ntau cov kab ke tseem ceeb rau lub neej
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
