Ob qho tib si diffusion thiab osmosis tsom kom sib npaug zog hauv cov hlwb thiab cov kab mob tag nrho, sib kis dej , cov as-ham thiab cov tshuaj tsim nyog los ntawm cov cheeb tsam uas muaj cov concentration siab rau cov cheeb tsam uas muaj cov concentration tsawg.
Ua li no, yog vim li cas diffusion tseem ceeb rau lub neej?
Kev nthuav tawm yog tseem ceeb rau cov kab mob vim nws yog cov txheej txheem uas muaj txiaj ntsig molecules nkag mus rau hauv lub cev hlwb thiab cov khoom pov tseg raug tshem tawm. Digested zaub mov molecules (amino acids, qabzib) txav mus rau ib tug concentration gradient los ntawm txoj hnyuv mus rau cov ntshav.
Ib sab saum toj no, puas yog osmosis thiab diffusion tseem ceeb rau tib neeg txoj sia nyob? Osmosis yog tseem ceeb tswj cov dej hauv cov hlwb. Nws yog lub luag haujlwm tseem ceeb hauv kev thauj cov kua dej hauv cov kab mob muaj sia. Yog tsis muaj cov txheej txheem ntawm osmosis lub cell yuav dehydrate thiab tuag.
Tom qab ntawd, lo lus nug yog, vim li cas osmosis tseem ceeb rau kev ua haujlwm ntawm tes?
Feem ntau muaj nuj nqi tseem ceeb ntawm osmosis yog stabilizing lub internal ib puag ncig ntawm ib tug kab mob los ntawm kev ua kom cov dej thiab intercellular kua theem sib npaug. Nyob rau hauv tag nrho cov muaj sia nyob, cov as-ham thiab minerals ua lawv txoj kev mus rau lub hlwb vim osmosis . Qhov no pom tseeb yog qhov tseem ceeb rau kev ciaj sia ntawm ib ntawm tes.
Yuav ua li cas diffusion cuam tshuam lub neej?
Hauv nyob yam, tshuaj txav mus rau hauv thiab tawm ntawm cov hlwb los ntawm nthuav tawm . Piv txwv li: Kev ua pa ua pa tawm cov pa roj carbon dioxide pov tseg, ua rau cov pa roj carbon dioxide nce hauv lub cell. Thaum kawg, cov pa roj carbon dioxide concentration hauv cell yog siab dua li cov ntshav nyob ib puag ncig.

Lawv yog cov yam ntxwv los ntawm tus nqi qis-tus nqi elasticity
Vim li cas thiaj tseem ceeb rau qhov tseem ceeb ntawm cov kev cai?
Kev xav tau qhov tseem ceeb yog siv hauv Software tswj cov khoom lag luam los txiav txim siab tus neeg sib tw cov cai ntawm cov khoom lag luam software yuav tsum suav nrog hauv qee qhov kev tso tawm. Cov kev cai tseem ceeb tseem ceeb kom txo qis kev pheej hmoo thaum lub sij hawm kev loj hlob kom cov kev cai tseem ceeb tshaj plaws los yog muaj kev pheej hmoo siab tau ua ntej
Vim li cas lub zog tseem ceeb heev hauv peb lub neej?
Lub zog yog qhov tseem ceeb rau lub neej thiab txhua yam muaj sia nyob. Lub hnub, ncaj qha lossis tsis ncaj, yog lub hauv paus ntawm txhua lub zog muaj nyob hauv lub ntiaj teb. Peb cov kev xaiv lub zog thiab kev txiav txim siab cuam tshuam rau lub ntiaj teb lub ntuj tsim hauv txoj hauv kev uas peb yuav tsis paub, yog li nws yog qhov tseem ceeb uas peb xaiv peb lub zog kom zoo
