Cytoplasmic division los yog Cytokinesis cais cov thawj cell, nws cov organelles thiab nws cov ntsiab lus rau hauv ob ntau los yog tsawg sib npaug halves.
theem ntawm lub voj voog ntawm tes yog kev faib ntawm cytoplasm?
Thaum interphase, lub cell loj hlob thiab ua ib daim qauv ntawm nws cov DNA. Thaum lub sijhawm mitotic (M) theem, lub xovtooj sib cais nws cov DNA ua ob pawg thiab faib nws cov cytoplasm, tsim ob lub hlwb tshiab.
txheej txheem twg cuam tshuam nrog kev faib cov cytoplasm?
Cytokinesis suav nrog kev faib ntawm cytoplasm tom qab karyokinesis. Lub cytokinesis yog ib qho kev sib cuam tshuam ntawm cell division. Nws cais cov cytoplasm niam cell ua ob me mentxhais hlwb. Nws tshwm sim rau ob hom kev faib atomic, mitosis thiab meiosis.

Thaum lub sijhawm ua pa ntawm tes uas ntawm cov hauv qab no tso tawm los ntawm cov khoom lag luam?
Thaum lub sijhawm ua pa aerobic cellular, qabzib reacts nrog oxygen, tsim ATP uas tuaj yeem siv los ntawm tes. carbon dioxide thiab dej yog tsim los ntawm cov khoom lag luam. Hauv kev ua pa ntawm tes, qabzib thiab oxygen hnov qab tsim ATP.
Lub sijhawm kuv lub sijhawm dawb lossis thaum kuv lub sijhawm dawb?
yog li, qhov no txhais tau tias "thaum kuv lub sijhawm dawb" tsis siv ntauthiab koj muab "hauv kuv lub sijhawm dawb" ntau dua nyob rau qhov kawg ntawm kab lus. Piv txwv li: Kuv tau taug kev tus dev thaum kuv lub sijhawm dawb.
Thaum lub sijhawm twg ntawm kev ua haujlwm yog qhov kev tshem tawm cov placenta quizlet?
Placental expulsion (tseem hu ua tom qab yug me nyuam) tshwm sim thaum tus placenta tawm ntawm lub qhov dej yug me nyuam tom qab yug me nyuam. Lub sij hawm txij li tom qab tus me nyuam raug tshem tawm mus txog rau thaum cov placenta raug tshem tawm yog hu ua theem thib peb ntawm kev ua haujlwm.
Rau lub hauv paus ntawm kev faib tawm cov qauv uas yog ib qho kev sib koom ua ke?
Daim duab 1. Sutures yog cov pob qij txha pom nyob hauv pob txha taub hau xwb. Syndesmoses yog cov pob qij txha uas cov pob txha txuas los ntawm ib pawg ntawm cov ntaub so ntswg sib txuas, tso cai rau kev txav mus los ntau dua li hauv suture.
Qhov twg yog qhov kev txiav txim siab rau kev tsis lees paub thiab rau kev ua kom muaj kev tawm tsam ntawm kev tawm tsam?
Kev qhuab ntuas tau siv los ntawm cov thawj coj loj hauv cov tub rog Romanrau txim rau cov koom haum lossis pab pawg loj ua txhaum cai, xws li kev ua phem, kev tawm tsam, kev tawm tsam, thiab kev tsis ncaj ncees, thiab rau lub pacification ntawm rebellious legions.
