Mitosis yog tus txheej txheem uas lub nucleus ntawm a eukaryotic cell faib. Thaum tus txheej txheem no, tus muam chromatids cais los ntawm txhua lwm yam thiab txav mus rau opposite ncej ntawm lub cell. Qhov no tshwm sim hauv plaub theem , hu ua prophase, metaphase, anaphase, thiab telophase.
Ntawm no, 4 theem ntawm mitosis yog dab tsi?
Mitosis muaj plaub theem pib: prophase , metaphase , anaphase , thiab telophase . Qee phau ntawv sau tsib, tawg prophase mus rau theem ntxov (hu ua prophase ) thiab theem lig (hu ua prometaphase).
Tsis tas li ntawd, cov theem ntawm cell faib yog dab tsi? Cov txheej txheem mitosis faib muaj ob peb kauj ruam lossis theem ntawm lub voj voog ntawm tes-interphase, prophase , prometaphase, metaphase , anaphase , telophase , thiab cytokinesis -kom ua tiav cov hlwb tshiab diploid.
Hauv qhov no, cov theem ntawm mitosis yog dab tsi thiab tshwm sim hauv txhua theem?
Mitosis muaj tsib theem sib txawv: interphase , prophase, metaphase , anaphase thiab telophase . Cov txheej txheem ntawm kev faib cell tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sijhawm anaphase thiab telophase . Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib.
Yuav ua li cas prophase?
Thawj theem thiab ntev tshaj plaws ntawm mitosis yog prophase . Thaum prophase , chromatin condenses rau hauv chromosomes, thiab lub hnab ntawv nuclear, lossis daim nyias nyias, tawg. Nyob rau hauv cov tsiaj hlwb, cov centrioles nyob ze ntawm lub nucleus pib sib cais thiab txav mus rau opposite ncej (sab) ntawm lub cell.

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
Ob theem tseem ceeb ntawm photosynthesis yog dab tsi thiab txhua theem tshwm sim nyob qhov twg?
Ob theem ntawm photosynthesis: Photosynthesis yuav siv sij hawm qhov chaw nyob rau hauv ob theem: lub teeb-dependent kev tshwm sim thiab lub Calvin voj voog (lub teeb-yooj yim kev xav). Lub teeb-nyob ntawm cov tshuaj tiv thaiv, uas tshwm sim hauv thylakoid daim nyias nyias, siv lub teeb lub zog los ua ATP thiab NADPH
Yuav ua li cas tshwm sim nyob rau hauv 4 theem ntawm mitosis?
Mitosis yog cov txheej txheem uas cov nucleus ntawm eukaryotic cell faib. Thaum lub sijhawm txheej txheem no, tus muam chromatids cais tawm ntawm ib leeg thiab txav mus rau cov ncej ntawm tes. Qhov no tshwm sim nyob rau hauv plaub theem, hu ua prophase, metaphase, anaphase, thiab telophase
Dab tsi tshwm sim hauv txhua theem ntawm mitosis?
Mitosis yog cov txheej txheem uas cov nucleus ntawm eukaryotic cell faib. Thaum lub sijhawm txheej txheem no, tus muam chromatids cais tawm ntawm ib leeg thiab txav mus rau cov ncej ntawm tes. Qhov no tshwm sim nyob rau hauv plaub theem, hu ua prophase, metaphase, anaphase, thiab telophase
Yuav ua li cas tshwm sim rau qhov teeb meem uas ploj ntawm txhua theem ntawm cov khoom noj khoom haus?
Lub zog tau dhau los ntawm cov khoom noj khoom haus los ntawm ib qib trophic mus rau lwm qhov. Txawm li cas los xij, tsuas yog kwv yees li 10 feem pua ntawm tag nrho lub zog khaws cia hauv cov kab mob ntawm ib qib trophic tau raug xa mus rau cov kab mob ntawm qib trophic tom ntej. Cov seem ntawm lub zog yog siv rau cov txheej txheem metabolic lossis poob rau ib puag ncig raws li cua sov
