Yooj yim Stain txheej txheem:
- Ntxuav thiab qhuav microscope slides kom huv si.
- Nplaim qhov chaw uas cov smear yuav kis tau.
- Nplaim lub voj inoculating.
- Hloov ib lub voj puv ntawm kais dej mus rau qhov flamed slide nto.
- Reflame lub voj kom paub tseeb tias tag nrho qhov ntev ntawm cov hlau uas yuav nkag mus rau hauv lub raj tau raug rhuab mus rau liab.
Ib yam li ntawd, tej zaum koj yuav nug, yog vim li cas rau qhov staining yooj yim?
Yooj Yim Staining Cov txheej txheem Cov molecules uas tsim cov dyes yooj yim muaj cov nqi zoo. Qhov no yog ib qho tseem ceeb vim hais tias cov phab ntsa ntawm tes thiab cytoplasm ntawm cov kab mob hlwb muaj cov nqi tsis zoo.
Ib yam li ntawd, dab tsi yog qhov yooj yim thiab sib txawv staining? A sib txawv stain yog hom tshwj xeeb ntawm staining uas tso cai rau kev txheeb xyuas microbe, thiab sib txawv ntawm cov hlwb hauv cov qauv sib xyaw. Yooj yim staining koom nrog ntxiv ib qho yooj yim, cationic dye rau lub cev. Qhov zoo dye yog attracted rau cov phab ntsa tsis zoo cell thiab cytoplasm, ua rau ua qias neeg hlwb.
Tsis tas li ntawd, cov txheej txheem staining tau faib li cas?
Mordants yog cais ua ob pawg: a) Basic Mordant: React with acidic dyes e.g. alum, ferrous sulfate, cetylpyridinium chloride thiab lwm yam. b) Acidic Mordant: React nrog cov xim yooj yim xws li. picric acid, tannic acid thiab lwm yam Direct Kev zas xim : Ua rau tsis muaj mordant.
Lub hauv paus ntsiab lus ntawm staining yog dab tsi?
Qhov yooj yim txoj cai ntawm Gram staining yog cov khoom ntawm qee cov kab mob ntawm cov phab ntsa kom khaws cov crystal violet dye. Li no, nws yog qhov txawv stain ? Safranin yog siv los ua lub txee stain hauv ib co staining raws tu qauv, coloring tag nrho cell nuclei liab.

Cov kauj ruam ntawm cov pa roj carbon monoxide yog dab tsi?
Cov txheej txheem hauv lub voj voog carbon Carbon nkag mus rau hauv huab cua raws li carbon dioxide los ntawm kev ua pa thiab combustion. Cov pa roj carbon dioxide yog absorbed los ntawm cov neeg tsim khoom los ua cov piam thaj hauv photosynthesis. Decomposers rhuav tshem cov kab mob uas tuag lawm thiab xa cov pa roj carbon monoxide hauv lawv lub cev rov qab mus rau qhov chaw zoo li carbon dioxide los ntawm kev ua pa
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Cov kauj ruam ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov?
Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase, anaphase thiab telophase. Cov txheej txheem ntawm cell faib tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sij hawm anaphase thiab telophase. Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib
Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
Lub hauv paus ntsiab lus ntawm staining yooj yim yog dab tsi?
Txoj Cai. Nws lub hauv paus ntsiab lus yog ua raws li lub hauv paus ntsiab lus ntawm kev ua kom pom qhov sib txawv ntawm lub cev thiab nyob ib puag ncig nws, los ntawm kev siv cov xim yooj yim. Ib qho yooj yim zas xim muaj cov chromophore zoo uas nyiam nyiam rau cov khoom tsis zoo ntawm tes thiab cov khoom siv hluav taws xob xws li nucleic acids thiab cov protein
