Kev nthuav tawm yog ib tug spontaneous txav ntawm hais los ntawm ib cheeb tsam ntawm siab concentration mus rau ib qho chaw uas tsis muaj concentration. Osmosis yog lub spontaneous net txav ntawm dej hla ib semipermeable daim nyias nyias los ntawm ib cheeb tsam uas tsis tshua muaj solute concentration mus rau ib tug ntau concentrated tov, nce ib tug concentration gradient.

Ib yam li ntawd, koj tuaj yeem nug, qhov txawv ntawm qhov sib txawv thiab osmosis yog dab tsi?

sib txawv : ua qhov sib txawv ntawm osmosis thiab nthuav tawm nws tias nthuav tawm hais txog kev txav mus los ntawm ib qho chaw mus rau lwm qhov, whereas osmosis tshwj xeeb yog hais txog kev txav ntawm cov dej hla ib daim nyias nyias. thiab nthuav tawm yog lub zog ntawm molecules (solute los yog hais).

Tsis tas li ntawd, dab tsi yog diffusion hauv hlwb? Cell diffusion yog hom passive ntawm tes thauj. Hauv nthuav tawm , molecules txav los ntawm qhov chaw siab concentration mus rau thaj chaw uas tsis muaj concentration thiaj li yuav txo cov concentration gradient. Kev nthuav tawm los ntawm cov cheeb tsam uas tsis tshua muaj siab mus rau qhov chaw siab concentration yog tsis muaj zog txaus nyiam.

Ua li no, osmosis thiab diffusion cuam tshuam li cas ntawm cov hlwb?

Piav: Lub ntawm tes membrane tseem hu ua selectively permeable membrane rau ib qho laj thawj vim nws yog xaiv nyob rau hauv xwm. Ib yam li hauv nthuav tawm thiab osmosis Tsuas yog qee cov molecules dhau los ntawm ntawm tes daim nyias nyias. Kev nthuav tawm pab kom dhau ntawm cov molecules tseem ceeb xws li dej, carbon di oxide thiab oxygen.

Dab tsi yog osmosis hauv cell?

zˈmo?.s?s/) yog lub spontaneous net txav ntawm hnyav molecules los ntawm ib tug selectively permeable daim nyias nyias mus rau hauv ib cheeb tsam ntawm ntau dua solute concentration, nyob rau hauv cov kev taw qhia uas nyhav sib npaug zos cov concentrations ntawm ob sab.
