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
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 qhov voltage ntawm ob theem hauv 3 theem khoom?
Voltage ntawm ob theem hu ua Kab voltage. Kab voltage = 1.73 * Phase voltage. Hluav taws xob hluav taws xob nruab nrab ntawm ib theem 'nyob' thiab 'tsis nruab nrab' hauv peb theem kev faib tawm yog 220 V
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog theem ib txwm thiab rov qab theem chromatography?
Nyob rau hauv ib txwm-theem chromatography, cov theem nyob ruaj ruaj yog polar thiab theem mobile tsis yog polar. Nyob rau hauv reversed theem peb muaj qhov opposite; Cov theem nyob ruaj ruaj yog nonpolar thiab theem mobile yog polar
