Concentration gradient - Lub zog ntawm osmosis yog cuam tshuam los ntawm concentration gradient ; qis tus concentration ntawm cov kuab tshuaj nyob rau hauv ib qho hnyav, qhov nrawm dua osmosis yuav tshwm sim hauv cov kuab tshuaj ntawd. Dej thiab Osmosis - Mus rau qhov txuas no thiab pom cov dej molecules txav mus hla ib daim nyias nyias nyias.
Ntawm no, qhov concentration gradient cuam tshuam li cas rau tus nqi ntawm diffusion?
Thaum nthuav tawm yuav mus tom ntej ntawm lub xub ntiag ntawm a concentration gradient ntawm ib yam khoom, ntau yam cuam tshuam tus nqi ntawm diffusion : Tshaj tawm ntawm concentration gradient : Qhov ntau dua qhov sib txawv hauv concentration , qhov nrawm dua nthuav tawm . Yog hais tias qhov nruab nrab yog tsawg ntom, nthuav tawm nce.
Qhov thib ob, yuav ua li cas thiaj muaj peev xwm cuam tshuam tus nqi ntawm osmosis? Solute peev xwm (Ψs) txo nrog nce daws concentration; qhov txo qis hauv Ψs ua rau txo qis hauv tag nrho cov dej peev xwm . Internal dej peev xwm ntawm cov nroj tsuag cell tsis zoo dua li cov dej ntshiab; Qhov no ua rau cov dej txav los ntawm cov av mus rau hauv cov cag ntoo ntawm osmosis ..
Ntawm no, qhov concentration ntawm ntsev hauv dej cuam tshuam li cas ntawm osmosis?
Ntsev ua rau osmosis los ntawm attracting lub dej thiab ua rau nws txav mus rau nws, hla daim nyias nyias. Ntsev yog ib tug solute. Thaum koj ntxiv dej mus rau ib tug solute, nws diffuses, nthuav tawm lub concentration ntawm ntsev , tsim kev daws teeb meem. Cells yuav tsis nce lossis poob dej yog muab tso rau hauv ib qho tshuaj isotonic.
Dab tsi yog qhov txawv ntawm concentration gradient thiab diffusion?
Cov qhov sib txawv ntawm qhov concentration ntawm ib yam khoom nruab nrab ob thaj chaw hu ua concentration gradient . Qhov loj dua sib txawv , lub steeper lub concentration gradient thiab qhov ceev cov molecules ntawm ib yam khoom yuav diffuse. Kev taw qhia ntawm nthuav tawm yog hais tias yuav 'down' los yog 'nrog' tus concentration gradient.

Yuav ua li cas tej yam ib puag ncig cuam tshuam tus nqi ntawm transpiration?
Txawm li cas los xij, muaj ntau yam tseem ceeb ntawm sab nraud uas cuam tshuam rau tus nqi ntawm transpiration, xws li: kub, lub teeb siv, av noo, thiab cua. Daim duab 5.14: Qhov qhib thiab kaw ntawm stomata. Txawv ib puag ncig tej yam kev mob ua rau ob qho tib si qhib thiab kaw ntawm stomata
Yuav ua li cas tshwm sim thaum lub concentration ntawm qabzib nyob rau hauv cov dej sab nraum lub cell yog siab tshaj qhov concentration nyob rau hauv?
Yog hais tias qhov concentration ntawm qabzib nyob rau hauv dej sab nraud ntawm lub cell yog siab tshaj qhov concentration hauv, dej yuav nyiam tawm hauv lub cell los ntawm osmosis. c. Cov piam thaj yuav zoo li nkag mus rau hauv lub cell los ntawm osmosis
Yuav ua li cas yog lub concentration gradient ntawm dej muaj feem xyuam rau osmotic siab?
Solute concentration yog siab dua nyob rau hauv lub cell. Yuav ua li cas yog qhov concentration gradient ntawm dej muaj feem xyuam rau osmotic siab? Qhov ntau dua qhov concentration ntawm dej hla ib daim nyias nyias, qhov siab dua osmotic. Osmosis yog cais raws li qhov tshwj xeeb ntawm daim ntawv ntawm kev thauj mus los ntawm daim nyias nyias?
Tib neeg cuam tshuam li cas cuam tshuam ntau yam ecosystem?
Tib neeg kev cuam tshuam rau lub ecosystem yog ib yam dab tsi ua los ntawm tib neeg thiab ua rau muaj kev cuam tshuam ntawm ecosystem xws li chopping down hav zoov, thiab tsheb hlawv tawm tsev cog khoom gases. Tib neeg tuaj yeem cuam tshuam rau ecosystem tsis zoo, los ntawm kev ua qias tuaj, pov tseg pov tseg, tua tsiaj, hla kev nuv ntses, kev lag luam gases, siv zog thiab tsis siv
Tus nqi nce nqi cuam tshuam li cas rau vaj tsev?
Thaum lub sij hawm nce nqi, tus nqi ntawm tag nrho cov khoom thiab cov kev pab cuam nce ntxiv, nrog rau cov nqi ntawm cov khoom. Yog li ntawd, ib zaug koj yuav ib lub tsev ntawm lub tsev qiv nyiaj ntawm tus nqi tas li ntawm cov paj laum, txhua xyoo, koj tau them tsawg dua (vim cov nyiaj tau txais txiaj ntsig nrog kev nce nqi)
