staining Ib tug txheej txheem nyob rau hauv uas hlwb los yog nyias seem ntawm lom cov ntaub so ntswg uas ib txwm pob tshab yog immersed nyob rau hauv ib los yog ntau xim dyes ( stains ) ua kom lawv pom meej dua los ntawm lub tshuab tsom. Kev pleev xim ua kom qhov sib txawv ntawm ntau yam ntawm tes los yog cov ntaub so ntswg.
Ua kom pom qhov no, dab tsi yog staining hauv biology?
Kev pleev xim yog ib qho txheej txheem siv hauv microscopy los txhim kho qhov sib txawv hauv cov duab microscopic. Stains thiab dyes yog nquag siv los qhia txog cov qauv hauv microbes rau kev saib, feem ntau nrog kev pab los ntawm ntau lub tshuab tsom.
Tsis tas li ntawd, dab tsi yog staining thiab hom staining? Hom ntawm Txawv Staining Cov txheej txheem ntawm Microorganisms. Kev pleev xim : Kev pleev xim tsuas yog txhais tau hais tias xim ntawm cov kab mob microorganisms nrog cov dyeing uas hais txog thiab elucidate txawv Cov qauv tseem ceeb ntawm cov kab mob xws li kab mob, kab mob, protozoa thiab lwm yam.
Ntawm no, dab tsi yog qhov txawv ntawm staining?
Ntau yam ntawm staining Cov txheej txheem tuaj yeem siv nrog lub teeb microscopy, suav nrog Gram staining , acid ceev staining , tshuaj ntsiav staining , endospore ua staining , thiab flagella staining.
Cov stains tseem ceeb yog dab tsi?
Nws yog yuav luag txhua qhov kev sim thawj zaug ua rau kev txheeb xyuas cov kab mob. Cov thawj stain ntawm Gram txoj kev yog siv lead ua violet. Cov kab mob cell phab ntsa yog stained los ntawm crystal violet. Tom qab ntawd iodine yog ntxiv los ua ib qho mordant los ua cov siv lead ua violet-iodine complex kom cov xim tsis tuaj yeem raug tshem tawm yooj yim.

Lub hom phiaj ntawm Congo Liab nyob rau hauv capsule staining yog dab tsi?
Qhov no yog cov txheej txheem tsis zoo staining uas yog qhov tseem ceeb siv los txheeb xyuas qhov muaj cov tshuaj ntsiav. Vim nws cov acidic xwm, India number case (los yog Congo liab, nigrosin) stains tom qab tsaus. Ntawm qhov tod tes, siv lead ua violet yog siv rau ntau qhov laj thawj xws li: los ua ib qho fixative. Ua kom lub zog nkag mus
Dab tsi yog qhov txhais ntawm lub hauv paus hauv biology?
Txhais. npe, plural: bases. (1) (molecular biology) Lub nucleobase ntawm nucleotide koom nrog hauv kev sib koom ua ke, xws li DNA lossis RNA polymer. (2) (anatomy) Qhov qis tshaj plaws los yog hauv qab ntawm cov nroj tsuag lossis tsiaj lub cev ze tshaj rau qhov txuas. (3) (chemistry) Ib qho dej-soluble compound uas reacts nrog acid thiab cov ntaub ntawv
Dab tsi yog txhais los ntawm staining hauv science?
Staining Ib cov txheej txheem uas cov hlwb los yog nyias ntu ntawm cov ntaub so ntswg uas ib txwm pob tshab yog immersed nyob rau hauv ib los yog ntau cov xim dyes (stains) kom lawv pom meej dua los ntawm lub tshuab tsom. Staining heightens qhov sib txawv ntawm ntau yam ntawm tes los yog cov ntaub so ntswg
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 txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
