Lub electron microscope
Cov hlwb muaj sia tsis tuaj yeem pom siv lub tshuab hluav taws xob microscope vim cov qauv muab tso rau hauv lub tshuab nqus tsev. Muaj ob hom electron microscope : qhov kis tau tus mob electron microscope (TEM) yog siv mus xyuas nyias slices los yog seem ntawm hlwb los yog cov ntaub so ntswg
Tsis tas li ntawd, hom microscope yog siv los soj ntsuam cov cell nyob?
Compound microscopes
Qhov thib ob, lub tshuab microscopes siv li cas hauv kev tshawb fawb ntawm cov hlwb? A cell yog qhov tsawg tshaj plaws ntawm lub neej. Feem ntau hlwb me me heev uas lawv tsis tuaj yeem pom ntawm qhov muag liab qab. Yog li ntawd, cov kws tshawb fawb yuav tsum siv microscopes rau kawm hlwb . Hluav taws xob microscopes muab kev nthuav dav dua, kev daws teeb meem siab dua, thiab nthuav dav ntau dua li lub teeb microscopes.
Yog li ntawd, hom microscopy twg muaj lub zog daws teeb meem loj tshaj?
Electron microscopes
Dab tsi yog siv los pom cov hlwb nyob?
Nyob ntawm tes imaging yog kev kawm ntawm nyob hlwb siv sijhawm-lapse microscopy. Nws yog siv los ntawm cov kws tshawb fawb kom tau txais kev nkag siab zoo ntawm kev ua haujlwm lom neeg los ntawm kev kawm ntawm cellular dynamics.

Darwin tau soj ntsuam dab tsi txog hom ntawm cov Islands tuaj?
Thaum nws mus ntsib Galapagos Islands, Charles Darwin nrhiav tau ntau hom finches uas txawv ntawm cov kob mus rau ib kob, uas pab nws tsim nws txoj kev xav ntawm kev xaiv ntuj
Cov ntaub ntawv dab tsi tuaj yeem txiav txim siab los ntawm kev soj ntsuam ib lub spectrum?
Lub stellar spectrum tuaj yeem nthuav tawm ntau yam khoom ntawm cov hnub qub, xws li lawv cov tshuaj muaj pes tsawg leeg, qhov kub thiab txias, qhov ntom ntom, qhov loj, qhov deb, luminosity, thiab kev txheeb ze ntawm kev siv Doppler hloov kev ntsuas
Dab tsi yog siv los soj ntsuam thiab piav txog qhov teeb meem?
Lub cev lub cev tuaj yeem soj ntsuam lossis ntsuas yam tsis tau hloov qhov muaj pes tsawg leeg ntawm cov teeb meem. Lub cev lub cev yog siv los soj ntsuam thiab piav txog qhov teeb meem. Lub cev muaj xws li: zoo li, kev ntxhib los mos, xim, tsw, melting point, boiling point, ntom, solubility, polarity, thiab ntau lwm yam
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Cov kev soj ntsuam soj ntsuam dab tsi qhia tias muaj kev hloov tshuaj lom neeg tshwm sim?
Kev soj ntsuam uas qhia tias muaj kev hloov pauv tshuaj muaj xws li kev hloov xim, hloov pauv kub, lub teeb muab tawm, tsim ua npuas, tsim cov nag lossis daus, thiab lwm yam
