sau 1,270 cov lus teb. StarTop kev kawm yog Science, Lej, thiab Kev Lag Luam. Laboratory apparatus yog cov khoom siv feem ntau thiab cov khoom siv uas koj xav tau thaum ua haujlwm ntawm tes-onactivities hauv a chav kuaj . Cov Laboratory apparatus nyob ntawm hom chav kuaj koj nyob hauv thiab qhov kev sim koj yuav ua.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog lub tshuab kuaj sim?
Cov cuab yeej kuaj yog cov cuab yeej thiab khoom siv siv los ntawm cov kws tshawb fawb uas ua haujlwm hauv a chav kuaj . Cov no tuaj yeem suav nrog cov cuab yeej xws li: Bunsen burners.burettes. calorimeters.
Ib yam li ntawd, lub luag haujlwm ntawm apparatus yog dab tsi? COMMON LABORATORY APPARATUS Beakers muaj txiaj ntsig asa cov tshuaj tiv thaiv lub thawv lossis tuav cov kua dej lossis cov khoom kuaj. Lawv kuj yog peb. Page 1. COMMON LABORATORY APPARATUS . Beakers siv tau los ua lub thawv tshuaj tiv thaiv lossis tuav cov kua lossis cov khoom siv.
Tsuas yog li ntawd, dab tsi yog cov cuab yeej kuaj thiab nws siv?
20 cov cuab yeej kuaj sim: lawv siv thiab npe
- Ib lub tshuab tsom. Biologists, cov neeg ua haujlwm kho mob, thiab cov tub ntxhais kawm nyiam siv lub tshuab tsom iav hauv lawv cov haujlwm.
- Triple beam balance. Cov cuab yeej kuaj mob dab tsi yog siv los ntsuas qhov hnyav?
- Volumetric khob.
- Ib lub raj.
- Ib tug bunsen burner.

Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Lub hauv paus ntsiab lus ntawm kev kuaj magnetic particle yog dab tsi?
Txoj kev sib nqus particle xeem ntawm Non-Destructive Examination yog tsim nyob rau hauv lub teb chaws USA, nyob rau hauv lub xyoo 1930s, raws li ib txoj kev los xyuas cov hlau Cheebtsam ntawm cov kab ntau lawm. Lub hauv paus ntsiab lus ntawm txoj kev yog tias cov qauv yog magnetized los tsim cov kab sib nqus ntawm lub zog, lossis flux, hauv cov khoom siv
Dab tsi yog lub ntsiab lus ntawm kab lus gene yog qhib?
Gene qhia yog cov txheej txheem uas cov lus qhia hauv peb DNA hloov mus rau hauv cov khoom siv, xws li cov protein. Gene qhia yog txheej txheem nruj nruj uas tso cai rau lub cell los teb rau nws qhov chaw hloov pauv
Dab tsi yog kev siv tus pas txhuam hniav hauv chav kuaj apparatus?
Ib lub khob nplawm pas nrig, iav pas nrig, nplawm pas nrig lossis nplawm pas nrig yog ib qho khoom siv hauv chav kuaj siv los sib tov tshuaj. Lawv feem ntau yog ua los ntawm cov iav khov, txog lub thickness thiab me ntsis ntev tshaj li ib tug haus straw, nrog rounded xaus
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
