Escherichia yog ib tug kab mob gram-negative, uas nyob rau hauv lub microscope Nws zoo li tus pas nrig nrog tus Tsov tus tw me me. Nws yog dav dav hauv qhov xwm txheej (Brooker 2008). Escherichiacoli ( E . coli ) yog ib feem ntawm cov plab hnyuv siab raum.
Tsis tas li ntawd nug, cov kab mob E coli zoo li cas hauv lub tshuab tsom?
E . Coli sub tus microscope ua 400x. E . Coli ( Escherichia Coli ) yog agram-negative, rod- zoo li tus kab mob. Feem ntau E . Coli hom kab mob yog tsis muaj mob, tab sis qee qhov serotypes ua tau ua rau zaub mov lom hauv lawv cov tswv. Cov tsis muaj mob yog ib feem ntawm qhov qub flora ntawm thegut.
Ib yam li ntawd, E coli puas yog Coccobacillus? Ib tug kab mob zoo li tus pas nrig yog E . coli . Lawv feem ntau yog me me, luv luv rods nrog ib tug rounding rau lawv, thiab raws li qhov tsawg magnification pom tshwm li cocci, txawm thinkhey yog pas nrig-puab. Ib qho kab mob coccobacillus Bordatellapertussis yog tus kab mob ua rau hnoos hawb pob.
Ib yam li ntawd, nws tau nug, koj puas tuaj yeem pom E coli nyob rau hauv lub tshuab tsom iav?
E . Coli Microscopy Txhawm rau txiav txim siab seb muaj kab mob (s) ntawm E . coli yog tam sim no nyob rau hauv ib tug qauv, nws yog tsim nyog los stain thesample. Ntawm no, Gram stain yog siv los ua kom paub qhov txawv ntawm cov kab mob gram zoo thiab gram tsis zoo (xws li E . coli ) hauv ib qho qauv.
Puas yog E coli muaj DNA lossis RNA?
genome qauv E . coli Nws tsuas muaj ib lub voj voog chromosome, qee qhov nrog rau lub voj voog plasmid. Nws chromosomal DNA tau ua tiav tiav los ntawm cov kws tshawb fawb lab. E . coli muaj ib tug chromosome uas muaj txog 4,600 kb, txog 4,300 muaj peev xwm coding sequences, thiab tsuas yog hais txog 1,800 paub E . coli cov proteins.

Puas yog Phosphorus yog hlau lossis tsis yog hlau?
Phosphorus yog cov hlau tsis muaj hlau uas nyob hauv qab nitrogen hauv pawg 15 ntawm lub sijhawm. Cov khoom no muaj nyob rau hauv ntau hom, uas yog dawb thiab liab yog qhov zoo tshaj plaws paub. Dawb phosphorus yog twv yuav raug hu ntau exciting ntawm ob
Puas yog E coli qws lossis cocci zoo li?
Kev faib tawm siab dua: Escherichia
Puas yog melting paraffin yog tshuaj los yog lub cev hloov?
Tab sis, thaum wax melts, nws yog ib qho kev hloov ntawm lub cev, vim hais tias nws tsuas yog hloov mus rau lwm lub xeev ntawm teeb meem. Tom qab ntawd thaum nws resolidifies, nws hloov rov mus rau hauv ib qho khoom. tswm ciab yog paraffin wax thiab ib qho aromatic compound nrog carbon saw. Kev kub hnyiab yog tshuaj lom neeg vim tias cov pa roj carbon dhau los ua cov pa roj carbon dioxide
Vim li cas koj thiaj tuaj yeem pom lub microscopic DNA yam tsis muaj lub tshuab tsom?
Nyob rau hauv lub tshuab microscope, paub txog ob-helix molecule ntawm DNA tuaj yeem pom. Vim tias nws nyias nyias, DNA tsis tuaj yeem pom los ntawm qhov muag liab qab tshwj tsis yog nws cov strands raug tso tawm los ntawm cov nuclei ntawm cov hlwb thiab tso cai rau pawg ua ke
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
