Khoom noj khoom haus kev noj tshuaj thiab tshuaj lom neeg dej haus yog qhov chaw ntawm kev raug tshuaj lom neeg. Yog li, tshuaj lom neeg raug tshwm sim thaum noj zaub mov los yog dej haus khaws cia nrog tshuaj. Yog li ntawd, noj lossis haus hauv lab yog txwv tsis pub.
Thiab cov lus nug yog, tsis txhob noj lossis haus hauv chav kuaj?
Noj , haus , haus luam yeeb, pos hniav zom, siv tshuaj pleev ib ce, thiab noj tshuaj nyob rau hauv chav kuaj qhov twg cov khoom siv phom sij yog siv yuav tsum nruj me ntsis txwv. Khoom noj khoom haus , dej haus, khob, thiab lwm yam haus thiab noj cov khoom siv yuav tsum tsis yog muab khaws cia rau hauv qhov chaw uas muaj cov khoom phom sij yog tuav los yog khaws cia.
Tsis tas li ntawd, vim li cas cov pos hniav tsis raug tso cai hauv cov chaw sim? Koj ua tsis tau zom gum hauv chemistry labs vim koj tsis paub tias nws yuav tua koj. Koj nyob hauv ib lab uas khaws ntau pua, tej zaum txawm ntau txhiab yam tshuaj sib txawv thiab cov khoom siv phom sij. Qee yam ntawm cov tshuaj no yog tshuaj lom.
Yog li ntawd, ua thiab tsis nyob hauv chav kuaj?
Ua thiab Tsis Ua hauv Science Lab
- Ua Hnav Qhov Muag Tiv Thaiv. Science labs muaj iav, tshuaj caustic, vapors, qhib nplaim taws thiab lwm yam khoom uas yuav ua rau koj ob lub qhov muag.
- Ua Xyaum Kev Nyab Xeeb Hluav Taws Xob.
- Ua Kho Cov iav kom zoo.
- Ua Khaws Cov Lus Cim.
- Ua Hnab looj tes.
- Hnav Khaub Ncaws Khaub Ncaws.
- Ua Xyaum Kev Nyab Xeeb Hluav Taws Xob.
- Tsis txhob noj lossis haus hauv chav kuaj.
Vim li cas thiaj tseem ceeb kom muaj cov cai hauv chav kuaj?
Los ntawm cov tshuaj mus rau cov khoom siv hluav taws xob, chav kuaj sau ntau yam kev nyab xeeb kev nyab xeeb, uas yog vim li cas nws tseem ceeb heev kom nkag siab txog qhov tseem ceeb ntawm lab kev nyab xeeb. Los ntawm kev paub txog lub chaw kuaj mob uas koj ua haujlwm hauv thiab ib txwm ua raws li cov txheej txheem kev nyab xeeb kom raug, koj tuaj yeem pab tiv thaiv lossis tshem tawm kev phom sij.

Lub npe ntawm cov enzyme uas kuaj pom hauv qhov kev kuaj pom zoo catalase yog dab tsi?
Catalase Test- Ntsiab Cai, Siv, Txheej Txheem, Txhais Lus Txhais nrog ceev faj. Qhov kev sim no qhia pom tias muaj catalase, ib qho enzyme uas ua rau cov pa tawm ntawm cov pa oxygen los ntawm hydrogen peroxide (H2O2)
Kev noj zaub mov zoo li cas yog siv los txhim kho kev noj qab haus huv?
Khoom noj khoom haus genomics muab cov txhais tau tias los tsim cov molecular biomarkers thaum ntxov, piv txwv li kev hloov pauv ntawm kev saib xyuas kev noj qab haus huv thiab kev loj hlob ntawm tus kab mob. Cov noob no tej zaum yuav raug siv los ua lub hom phiaj los txheeb xyuas cov khoom noj khoom haus uas muaj peev xwm hloov kho lawv cov kev qhia
Koj tsis noj hauv chav kuaj?
Noj, haus thiab siv tshuaj pleev ib ce hauv lub Lab. Kev noj zaub mov thiab dej haus uas muaj tshuaj lom neeg yog qhov chaw ntawm cov tshuaj lom neeg. Yog li, kev raug tshuaj lom neeg tshwm sim thaum noj zaub mov lossis dej haus khaws cia nrog tshuaj. Yog li ntawd, noj lossis haus hauv chav kuaj yog txwv tsis pub noj
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
