Thaum muaj cov tshuaj tiv thaiv hauv qhov xwm txheej, thiab nws tsim cov tshuaj lom neeg, peb tuaj yeem muab cov tshuaj tiv thaiv ntawd tso rau hauv ib qho ntawm plaub pawg: additive, synergistic, antagonistic, thiab potentiating.
kev sib koom ua ke thiab kev tawm tsam yog dab tsi?
Yog li, kev sib koom ua ke yog siv los txhais cov txiaj ntsig ntawm ntau qhov kev ntxhov siab uas ntau dua li cov txiaj ntsig ntxiv ntawm cov teebmeem ua los ntawm cov kev ntxhov siab ua rau kev sib cais; qhov no sib piv nrog lo lus "antagonism," siv los txhais cov txiaj ntsig uas tsawg dua qhov ntxiv (Hay li al.
Yuav ua li cas thaum muaj tshuaj lom neeg tshwm sim?
Hauv cov tshuaj tiv thaiv tshuaj, cov atoms thiab molecules uas cuam tshuam nrog ib leeg hu ua reactants.… Tsis muaj cov atom tshiab tsim, thiab tsis muaj atoms raug puas tsuaj. Nyob rau hauv cov tshuaj tiv thaiv tshuaj, reactants sib cuag, bonds ntawm atoms nyob rau hauv cov reactants tawg, thiab atoms rearrange thiab tsim tshiab bonds los ua cov khoom
Dab tsi yog kev tawm tsam?
Definition: A biologic teb kom raug ntau yam tshuaj uas tsawg tshaj li qhov xav tau yog tias paub txog cov teebmeem ntawm tus kheej tau ntxiv ua ke.
Ib qho piv txwv ntawm cov nyhuv additive yog dab tsi?
Kev sib cuam tshuam ntxiv txhais tau tias cov nyhuv ntawm ob yam tshuaj sib npaug ntawm cov txiaj ntsig ntawm ob yam tshuaj noj sib cais. Qhov no feem ntau yog vim ob yam tshuaj ua haujlwm ntawm lub cev ntawm tib yam lossis zoo sib xws. Piv txwv yog aspirin thiab motrin, cawv thiab kev nyuaj siab, tranquilizer thiab painkiller

Puas yog ib qho tseem ceeb ntawm cov tshuaj lom neeg lom neeg ntawm thiols?
Dab tsi ntawm cov hauv qab no yog qhov tseem ceeb ntawm cov tshuaj lom neeg lom neeg ntawm thiols? kev oxidation ntawm ob thiols los ua ib tug disulfide . Yam thiols yog dab tsi? 1 BIOLOGICAL THIOLS Thiols xa mus rau chav kawm ntawm cov organic sulfur derivatives uas yog tus cwj pwm los ntawm qhov muaj sulfhydryl residues (–SH) ntawm lawv qhov chaw nquagTshuaj, thiols yog mercaptans (C-SH) thiab biological mercaptans feem ntau hu ua biological thiols lossis biothio
Puas yog txhua plaub plaub plaub plaub plaub fab?
Ib daim duab plaub yog ib qho parallelogram nrog plaub lub kaum sab xis, yog li tag nrho cov duab plaub yog kuj parallelograms thiab quadrilaterals. Ntawm qhov tod tes, tsis yog txhua qhov quadrilaterals thiab parallelograms yog cov duab plaub.
Thaum cov kuab tshuaj evaporates dab tsi tshwm sim rau qhov concentration ntawm cov tshuaj?
Qhov no txhais tau hais tias yog tias koj cov kuab tshuaj evaporating thiab qhov kub thiab txias tsis tu ncua, ces solute yuav precipitate tawm ntawm cov tshuaj. Qhov concentration ntawm cov tshuaj yuav tseem nyob rau ntawm nws qhov siab tshaj plaws raws li koj muaj kev txhawj xeeb nrog cov nyiaj solute yaj .
Puas qhia tias muaj tshuaj lom neeg tshwm sim?
tsib yam kev hloov tshuaj lom neeg: xim hloov, tsim cov nag lossis daus, tsim cov roj, tsw hloov, kub hloov . Qhov piv txwv twg qhia tau tias muaj kev hloov tshuaj lom neeg? Kev soj ntsuam uas qhia tias muaj kev hloov pauv tshuaj muaj xws li xim hloov, hloov kub, lub teeb tawm, tsim npuas, tsim cov nag lossis daus, thiab lwm yam .
Puas muaj qhov sib txawv ntawm qhov tshwm sim thiab qhov tshwm sim?
Raws li lub npe qhov txawv ntawm qhov tshwm sim thiab qhov tshwm sim. yog happenchance is a coincidental happen while happenstance is (countable) a chance or random event or random events . Puas muaj lo lus tshwm sim? : a xwm txheej tshwj xeeb yog vim muaj caij nyoog Lawv tuaj ua ke los ntawm qhov tshwm sim .
