Kev faib tawm siab dua: Escherichia
Kuj paub, dab tsi zoo li Escherichia coli hlwb?
E . coli yog Gram-negative rod-shapedbacteria, uas muaj cov nplaum fimbriae thiab cell Phab ntsa uas muaj cov txheej txheem sab nrauv uas muaj lipopolysaccharides, qhov chaw periplasmic nrog txheej peptidoglycan, thiab sab hauv, cytoplasmic membrane.
Tsis tas li ntawd, tus kab mob streptococcus yog dab tsi? Cell Structure thiab Metabolism Electron micrograph ntawm Streptococcus pyogenes. Los ntawm Rockefeller University. Streptococci yog nonmotile, Gram-positive, nonsporeforming kab mob, uas nyob rau hauv khub orchains ntawm txawv ntev. Lawv yog cov yam ntxwv puag ncig orovoid nyob rau hauv puab.
Ib sab saum toj, vim li cas E coli qws zoo li?
Escherichia coli yog a rod - zoo li tus kab mob. E . coli yog a Gram -negativebacterium. E . coli hlwb stain Gram tsis zoo vim tias lawv muaj cov phab ntsa nyias nyias nrog tsuas yog 1 mus rau 2 txheej ntawm peptidoglycan. E . coli yog facultative anaerobe, uas txhais tau hais tias nws tsis xav tau oxygen, tab sis loj hlob zoo dua nyob rau hauv muaj oxygen.
Hom kab mob twg muaj tus qauv zoo li tus pas nrig?
Peb qhov yooj yim Cov kab mob kab mob yog coccus( kheej kheej ), bacillus ( rod - zoo li tus ), thiab kauv (twisted), txawm li cas los xij pleomorphic kab mob tuaj yeem ua ntau yam cov duab.

Puas yog gal4 protein nyob rau hauv cov poov xab ua tau zoo lossis tsis zoo ntawm GAL noob?
Gal4 transcription yam yog ib tug zoo regulator ntawm noob qhia ntawm galactose-induced noob. Cov protein no sawv cev rau tsev neeg loj ntawm cov kab mob ntawm cov kab mob, Gal4 tsev neeg, uas suav nrog ntau dua 50 tus tswv cuab hauv cov poov xab Saccharomyces cerevisiae xws li. Oaf1, Pip2, Pdr1, Pdr3, Leu3
Puas yog Gram zoo lossis tsis zoo txaus ntshai?
Hauv kev sib piv rau Gram zoo, cov kab mob Gram-negative muaj kev phom sij ntau dua li cov kab mob, vim muaj cov tshuaj ntsiav los yog cov slime txheej uas npog lub txheej membrane. Ua raws li txoj kev no, cov kab mob micro tuaj yeem nkaum nws cov antigens saum npoo uas yuav tsum tau ua rau tib neeg lub cev tiv thaiv kab mob
Puas yog tib neeg lub hlwb Gram zoo lossis Gram tsis zoo?
Tib neeg lub hlwb tsis muaj cov phab ntsa ntawm tes lossis Peptidoglycan (PDG). Cov hlwb tuaj yeem coj cov xim stain. Ib qho ntawm koj cov neeg koom tes hauv chav kuaj tau ua raws li cov txheej txheem pom zoo ntawm kev khiav Gram-positive thiab Gram-negative tswj kab mob ntawm nws Gram stain ntawm ib hom tsis paub
Puas yog capacitive reactance zoo lossis tsis zoo?
Capacitive reactance Ib qho hluav taws xob DC siv hla lub capacitor ua rau cov nqi zoo sib sau rau ntawm ib sab thiab cov nqi tsis zoo los mus rau sab nraud; lub teb hluav taws xob vim yog cov khoom siv hluav taws xob yog qhov kev tawm tsam ntawm qhov tam sim no
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
