Mitosis (ib theem hauv lub voj voog ntawm tes) tshwm sim Tom qab DNA nyob rau hauv ib lub cell tau duplicated, txhais tau tias muaj ob pawg ntawm chromosomes nyob rau hauv ib lub cell. Qhov tshwm sim ntawm mitosis tsis muaj cytokinesis yuav ua ib lub cell uas muaj ntau tshaj ib lub nucleus. Xws li ib tug cell hu ua multinucleated cell. Qhov no ua tau ua ib tug txheej txheem.
Hauv qhov no, mitosis puas tuaj yeem tshwm sim thaum tsis muaj cytokinesis?
Mitosis tuaj yeem tshwm sim thaum tsis muaj cytokinesis vim cytokinesis tshwm sim tom qab mob mitosis . Xwb, txij li thaum cytokinesis tsis yog tshwm sim , cov nucleus yuav txuas ntxiv faib thiab dhau los ua ib lub cell loj. Daim duab hauv qab no qhia txog kev faib cell hauv tib neeg testis. Cov noob qes yog gametes.
Tom qab ntawd, lo lus nug yog, hom cell twg tsis raug cytokinesis? Cov cell Lub voj voog culminates hauv kev faib ntawm cytoplasm los ntawm cytokinesis . Hauv ib txwm cell , cytokinesis nrog txhua mob mitosis , txawm tias ib txhia hlwb , xws li Drosophila embryos (sib tham tom qab) thiab vertebrate osteoclasts (sib tham hauv Tshooj 22), raug mitosis tsis muaj cytokinesis thiab ua multinucleate.
Puas yog mitosis thiab cytokinesis xav tau rau kev yug me nyuam asexual?
Mitosis tsim cov nuclei tshiab nrog tib yam chromosomal endowment raws li niam txiv nucleus. C) Mitosis thiab cytokinesis yog xav tau rau kev yug me nyuam asexual.
Ib qho piv txwv ntawm cytokinesis yog dab tsi?
ib qho ntawm ntau yam tshuaj, xws li interferon, interleukin, thiab kev loj hlob yam tseem ceeb, uas tau zais los ntawm qee lub hlwb ntawm lub cev tiv thaiv kab mob thiab muaj kev cuam tshuam rau lwm lub hlwb.

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
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
Dab tsi yog tsib yam pov thawj uas koj tuaj yeem siv los txiav txim seb puas muaj tshuaj lom neeg tshwm sim?
Qee cov cim qhia txog kev hloov tshuaj lom neeg yog kev hloov xim thiab tsim cov npuas. Lub tsib yam kev hloov ntawm tshuaj lom neeg: xim chage, tsim ntawm precipitate, tsim cov roj, tsw hloov, kub hloov
Qhov txheej twg yog huab cua tshwm sim feem ntau tshwm sim?
Troposphere. Lub troposphere (los ntawm Greek: tropein - hloov, ncig lossis sib xyaw) yog txheej qis tshaj plaws ntawm lub ntiaj teb huab cua. Feem ntau ntawm huab cua phenomena, systems, convection, turbulence thiab huab tshwm sim nyob rau hauv no txheej, tab sis tej zaum yuav mus rau hauv lub qis feem ntawm thestratosphere
Puas muaj pyruvate oxidation tshwm sim tsis muaj oxygen?
Yog tsis muaj oxygen, pyruvate (pyruvic acid) tsis metabolized los ntawm cellular respiration tab sis undergoes tus txheej txheem ntawm fermentation. Cov pyruvate tsis thauj mus rau hauv mitochondrion, tab sis tseem nyob hauv cytoplasm, qhov chaw nws hloov mus rau cov khoom pov tseg uas yuav raug tshem tawm ntawm lub cell
