Forceps . Siv los khaws lossis tuav cov khoom me me.
Piv txwv li, dab tsi yog forceps siv rau hauv chemistry?
Forceps . Forceps yog cov "tweezers" hauv cov organic chem lab. Lawv tuaj nyob rau hauv ntau qhov ntau thiab tsawg, qee zaum laus thiab tsis muaj xim, qee zaum tshiab thiab ci, qee zaum ntse thiab taw tes, qee zaum tiaj tus. Forceps yog siv rau txhua qhov xwm txheej uas koj yuav tsum lob ib yam khoom me me thiab ua tsis tau nrog koj tus ntiv tes.
Ib yam li ntawd, Scoopula siv rau dab tsi? Scoopula yog ib lub npe ntawm cov khoom siv spatula zoo li rab diav siv Feem ntau nyob rau hauv chemistry lab teeb tsa kom hloov cov khib nyiab: mus rau ib daim ntawv hnyav rau qhov hnyav, mus rau ib daim npog npog los ntsuas qhov melting point, los yog ib lub tog raj kheej kawm tiav, los yog mus rau lub iav saib los ntawm lub hwj los yog beaker los ntawm scraping.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog cov cuab yeej kuaj thiab lawv txoj haujlwm?
Cov cuab yeej koj yuav ntsib thiab lawv txoj haujlwm
- Cov tsom iav tsom iav thiab cov khoom siv kev nyab xeeb.
- Beakers.
- Erlenmeyer flasks, AKA conical flasks.
- Florence flasks, AKA boiling flasks.
- Test tubes raug lifted nrog tongs los ntawm ib tug khib.
- Saib tsom iav.
- Crucibles.
- Funnels.
Dab tsi yog cov cuab yeej siv hauv chav kuaj?
| Lub npe | Siv |
|---|---|
| Graduated Cylinders (iav lossis yas) | Siv los ntsuas cov kua ntim. Cov cuab yeej muaj tseeb heev. Kawm tiav hauv mL. |
| Beaker (iav los yog yas) | Siv los do, kub (yog tias iav), thiab ntsuas cov kua ntim hauv mL (kwv yees ntxhib). |
| Beaker Tongs | Siv los tuav cov khob kub kub. |
| Florence Flask | Cov iav siv los ua kom sov thiab khaws cov khoom. |

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog lub luag haujlwm tseem ceeb ntawm mitochondria hauv hlwb quizlet?
Lawv yog ib qho tseem ceeb vim hais tias lawv loj heev nce lub organelle cheeb tsam, uas yog tsim nyog los ua kom haum cov protein ntau complexes yuav tsum tau rau electron thauj thiab ATP synthesis
Lub luag haujlwm tseem ceeb ntawm lub teeb pom kev ntawm photosynthesis yog dab tsi?
Lub luag haujlwm tag nrho ntawm cov tshuaj tiv thaiv lub teeb, thawj theem ntawm photosynthesis, yog hloov lub hnub ci zog rau hauv cov tshuaj siv hluav taws xob nyob rau hauv daim ntawv ntawm NADPH thiab ATP, uas yog siv nyob rau hauv lub teeb-yooj yim tshuaj tiv thaiv thiab roj sib sau ua ke ntawm qab zib molecules
Dab tsi yog lub luag haujlwm tseem ceeb ntawm phospholipid bilayer hauv cellular membrane?
Lipid Bilayer Structure Lub lipid bilayer yog ib qho universal feem ntawm tag nrho cov cell membranes. Nws lub luag haujlwm tseem ceeb heev vim tias nws cov qauv tsim muaj qhov cuam tshuam uas ua rau cov ciam teb ntawm lub xov tooj ntawm tes. Cov qauv hu ua 'lipid bilayer' vim tias nws yog tsim los ntawm ob txheej ntawm cov roj ntsha hauv ob daim ntawv
