Cov txheej txheem biological yog txoj kev los yog cov txheej txheem uas siv los kawm txog tej yam muaj sia. Lawv suav nrog kev sim thiab suav txoj kev , le caag, raws tu qauv thiab cov cuab yeej rau lom kev tshawb fawb.
Ib yam li ntawd, txoj kev lom neeg yog dab tsi?
Cov txoj kev lom neeg hais txog bioremediation, uas lom Cov txheej txheem (cov kab mob microorganisms) yog siv los degrade thiab metabolize tshuaj lom neeg thiab rov ua kom zoo ib puag ncig. Ob qho tib si paraffinic thiab aromatic hydrocarbons tuaj yeem degraded los ntawm ntau yam kab mob, tab sis muaj qhov sib txawv degradation.
Cov txheej txheem biochemical yog dab tsi? Cov txheej txheem biochemistry yog Protein Purification, perfusion, Homogenization, Differential centrifugation, Purification ntawm LDH, Purification ntawm LDH, LDH Enzyme assays, Protein assays, Characterization of LDH, Western blotting, Gel filtration chromatography, Protein crystallography, PCR, Ligation thiab transformation, Raws li txoj cai, cov cuab yeej lom neeg yog dab tsi?
Molecular cov cuab yeej siv roj ntsha yog cov thev naus laus zis uas lub hom phiaj biomarkers (piv txwv li, tshwj xeeb nucleic acid sequences, peptides, proteins, los yog lipids) los muab cov ntaub ntawv hais txog cov kab mob thiab cov txheej txheem cuam tshuam rau kev ntsuam xyuas thiab / lossis kho cov kab mob hauv ib puag ncig lossis lwm lub tshuab ua haujlwm.
Vim li cas peb kawm txog cov txuj ci lom neeg?
Cov txheej txheem thiab Cov txheej txheem hauv Molecular Biology . Molecular Cov txheej txheem biology siv rau kawm lub hauv paus molecular ntawm lom kev ua si. Cov no txoj kev siv los tshawb xyuas cov hlwb, lawv cov yam ntxwv, qhov chaw, thiab cov txheej txheem tshuaj lom neeg, thiab them nyiaj tshwj xeeb rau cov molecules tswj cov haujlwm ntawm tes thiab kev loj hlob.

Dab tsi yog cov txheej txheem uas tsim cov ntawv luam tshiab ntawm cov kab mob caj ces?
Cov txheej txheem ntawm DNA replication tsim ib daim qauv tshiab ntawm cov kab mob cov ntaub ntawv caj ces kom dhau mus rau lub cell tshiab. Dawb ntab nucleotides yog txuam nrog lawv cov lus qhuas los ntawm ib qho enzyme hu ua polymerase. Cov no yog 'lub tsev.' Lawv sib sau ua ke DNA tshiab strand nrog txhua tus qub strands
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Dab tsi yog txheej txheem biological hauv geography?
WP. Txhais: Cov txheej txheem lom neeg yog cov txheej txheem tseem ceeb rau lub cev muaj sia nyob. Cov txheej txheem lom neeg yog tsim los ntawm ntau yam tshuaj lom neeg lossis lwm yam xwm txheej uas ua rau muaj kev hloov pauv tshuaj lom neeg. Metabolism thiab homeostasis yog cov piv txwv
Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?
Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud
Cov txheej txheem twg yog txheej txheem endothermic?
Cov txheej txheem endothermic yog ib qho txheej txheem uas xav tau lossis nqus lub zog los ntawm nws qhov chaw nyob ib puag ncig, feem ntau yog ua kom sov. Nws yuav yog cov txheej txheem tshuaj, xws li dissolving ammonium nitrate hauv dej, lossis cov txheej txheem ntawm lub cev, xws li melting ntawm cov dej khov nab kuab
