cell tsis tu ncua . ['sel'kän·st?nt] (physical chemistry) Qhov piv ntawm qhov deb ntawm conductance-titration electrodes mus rau thaj tsam ntawm cov electrodes, ntsuas los ntawm kev txiav txim siab ntawm kev daws teeb meem ntawm kev paub tshwj xeeb conductance.
Ntxiv mus, cell tas li thiab nws chav nyob yog dab tsi?
Cov cell tsis tu ncua yog lub luag haujlwm ntawm electrodeareas, qhov kev ncua deb ntawm cov electrodes thiab hluav taws xob fieldpattern ntawm cov electrodes. Chav tsev ntawm cellconstant yog cm-1 los yog m-1.
Vim li cas KCL siv rau kev txiav txim siab ntawm tes tsis tu ncua? Nws yog feem ntau txwv rau kev ntsuas ntawm ultrapurewater, qhov conductivity ntawm uas yog tsawg heev. Kev txiav txim siab ntawm cell tsis tu ncua yuav tsum tau hloov pauv conductance nyeem-ings rau hauv cov txiaj ntsig conductivity. Ib qho kev daws teeb meem ntawm paub conductivity uas yog siv los calibrate cov conductivity measuringchain.
Hauv qhov no, cell constant formula yog dab tsi?
Cell tas li yog tshwj xeeb cell yog txiav txim siab raws li qhov piv ntawm qhov kev ncua deb ntawm cov electrodes ofthe cell mus rau thaj tsam ntawm cov electrodes. cell tsis tu ncua K = l/A = cm.
Dab tsi yog txhais los ntawm conductivity cell?
k'tiv·?d·sel] (hluav taws xob) Ib lub raj iav nrog ob lub electrodes ntawm qhov sib nrug deb li deb thiab ntim nrog cov tshuaj uas nws conductivity yog yuav tsum ntsuas.

Dab tsi yog qhov txawv ntawm tsiaj cell thiab cog cell?
Qhov sib txawv ntawm cov nroj tsuag thiab cov tsiaj hlwb yog tias cov tsiaj txhu feem ntau yog puag ncig thaum cov nroj tsuag feem ntau yog cov duab plaub. Cov nroj tsuag muaj cov phab ntsa tawv tawv uas nyob ib puag ncig cov cell membrane. Tsiaj cell tsis muaj phab ntsa ntawm tes
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 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
Lub ntsiab lus ntawm cog cell thiab tsiaj cell yog dab tsi?
Tsiaj Thiab Nroj Tsuag Cell. Txhua yam muaj sia nyob, nroj tsuag lossis tsiaj txhu yog tsim los ntawm cov hlwb. Lub cytoplasm nyob rau hauv ib lub cell muaj chloroplast thiab lwm yam plastids, mitochondria, dictyosomes, ribosomes, du thiab ntxhib endoplasmic reticulum, nucleus thiab lwm yam. Ib tug tsiaj cell yog ntau dua los yog tsawg spherical
Dab tsi yog cell membrane hauv prokaryotic cell?
Prokaryotes thiab eukaryotes yog ob hom cell uas muaj nyob. Tab sis, prokaryotes muaj qee cov organelles nrog rau cov cell membrane, kuj hu ua phospholipid bilayer. Cov cell membrane no kaw lub cell thiab tiv thaiv nws, tso cai rau hauv qee cov molecules raws li qhov xav tau ntawm tes
