Mitosis pib ntawm prophase nrog lub thickening thiab coiling ntawm chromosomes. Lub nucleolus, ib puag ncig qauv, shrinks thiab ploj. Qhov kawg ntawm prophase yog cim los ntawm pib ntawm lub koom haum ntawm ib pawg ntawm fibers los tsim ib tug ntxaiv thiab lub disintegration ntawm lub nuclear membrane
Qhov tshwm sim ntawm prophase yog dab tsi?
Thaum lub sijhawm prophase, qhov nyuaj ntawm DNA thiab cov proteins muaj nyob hauv cov nucleus, hu ua chromatin, condenses. Cov chromatin coils thiab dhau los ua compact, ua rau tsim ntawm pom chromosomes.
Yuav ua li cas 3 yam tshwm sim hauv prophase?
Cov xwm txheej tseem ceeb ntawm prophase yog: qhov condensation ntawm chromosomes, txav ntawm centrosomes, tsim cov mitotic spindle, thiab pib ntawm nucleoli tawg.
Qhov twg ntawm cov no tau tshwm sim los ntawm qhov kawg ntawm telophase?
Mitosis xaus nrog telophase, lossis theem uas cov chromosomes ncav cuag tus ncej. Cov ntaub so ntswg nuclear tom qab ntawd hloov kho, thiab cov chromosomes pib decondense rau hauv lawv cov kev sib tshuam. Telophase yog ua raws li cytokinesis, lossis faib cov cytoplasm rau hauv ob lub hlwb.
Koj tuaj yeem qhia tau li cas yog tias lub xov tooj ntawm tes nyob hauv telophase?
Thaum koj saib ntawm lub xov tooj ntawm tes hauv telophase hauv qab lub tshuab tsom, koj yuav pom DNA ntawm ob tus ncej. Tej zaum nws tseem nyob hauv nws lub xeev condensed los yog thinning tawm. Cov nucleoli tshiab tuaj yeem pom, thiab koj yuav pom lub cell membrane (los yog cell phab ntsa) ntawm ob lub cell.

Nyob rau ntawm qhov chaw kaw dab tsi tshwm sim thaum kawg?
Peb tau qhia hauv Shutter Island xaus tias kev vwm coj Andrew hla, thiab nws tua Dolores tuag Andrew mus vwm thiab nws lub siab tsis tuaj yeem ntsib qhov nws tau ua. Nws tau txais nyob rau hauv Ward C ntawm lub chaw kho mob hlwb (Ashecliffe) ntawm Shutter Island.
Puas muaj qhov sib txawv ntawm qhov tshwm sim thiab qhov tshwm sim?
Raws li lub npe qhov txawv ntawm qhov tshwm sim thiab qhov tshwm sim. yog happenchance is a coincidental happen while happenstance is (countable) a chance or random event or random events . Puas muaj lo lus tshwm sim? : a xwm txheej tshwj xeeb yog vim muaj caij nyoog Lawv tuaj ua ke los ntawm qhov tshwm sim .
Lub sijhawm redox tshwm sim dab tsi tshwm sim?
Dab tsi tshwm sim hauv Oxidation-Reduction (Redox) Reaction? Electrons raug xa los ntawm ib qho reactant mus rau lwm qhov thiab oxidation xeev / oxidation naj npawb oxidation tooj Qhov nce hauv oxidation lub xeev ntawm atom, los ntawm cov tshuaj tiv thaiv, hu ua oxidation;
Dab tsi ntawm qhov tshwm sim hauv qab no tau sim ua pov thawj los ntawm meselson thiab stahl?
Kev sim Meselson thiab Stahl yog ib qho kev sim los ua pov thawj tias DNA replication yog semiconservative semiconservative Semiconservative replication piav txog lub mechanism ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb… Cov txheej txheem no paub raws li ib nrab kev saib xyuas rov ua dua vim tias ob daim ntawv theej ntawm thawj DNA molecule raug tsim, txhua daim ntawv khaws cia (replicating) cov ntaub ntawv los ntawm ib nrab ntawm thawj DNA molecule.
Dab tsi tshwm sim tshwm sim joe txoj kev hlub rau jazz?
Joe Gardner yog ib tus kws qhia ntawv hauv tsev kawm theem nrab uas tau ua npau suav ntev txog kev ua suab paj nruag jazz, thiab thaum kawg tau txais lub sijhawm tom qab ua rau ob tus neeg ntaus suab paj nruag jazz thaum lub sijhawm qhib kev ua yeeb yam ntawm Half Note ClubThaum nws tab tom ua kev zoo siab rau nws qhov kev ua koob tsheej tshiab, nws tau poob rau hauv qhov chaw .
