Osmosis. Osmosis yog kev txav ntawm cov dej hla ib daim nyias nyias los ntawm thaj tsam ntawm qhov tsis tshua muaj kuab lom mus rau thaj tsam ntawm cov kua qaub siab.
Yuav ua li cas yog qhov kev txav ntawm cov kua nplaum hla lub cell membrane?
Kev txav ntawm cov kua nplaum hla cov daim nyias nyias tuaj yeem muab faib ua ob hom: passive diffusion thiab nquag thaujPassive diffusion yuav tsum tsis muaj lub zog ntxiv dua li qhov muaj nyob hauv cov kua nplaum electrochemical (concentration) gradient thiab ua rau cov kua nplaum ncav cuag equilibrium hla daim nyias nyias.
YPuas osmosis kev txav ntawm cov kua nplaum hla ib daim nyias nyias?
Osmosis yog kev txav dej ntawm cov dej hla ib qho kev xaiv permeable daim nyias nyiasuas tau tsav los ntawm qhov sib txawv ntawm cov ntsiab lus ntawm ob sab ntawm daim nyias nyias. Ib qho kev xaiv permiable membrane yog ib qho uas tso cai rau cov dej tsis muaj kev txwv, tab sis tsis yog cov kuab tshuaj molecules lossis ions.
Yam yooj yim txav hla ib daim nyias nyias hu ua dab tsi?
" Yooj yim diffusion." Yooj yim diffusion yog zoo nkauj npaum li cas nws suab zoo li - molecules txav mus rau lawv gradients los ntawm daim nyias nyias. Molecules uas xyaum yooj yim diffusion yuav tsum me me thiab nonpolar, thiaj li yuav kis tau los ntawm daim nyias nyias.
Puas yog diffusion Lub zog ntawm cov tshuaj?
Diffusion yog qhov txav ntawm cov molecules los ntawm thaj chaw siab ntawm cov molecules mus rau thaj chaw uas muaj qhov qis dua… qis dua, nws tau piav raws li txav cov tshuaj "down the concentration gradient ".

Pcos puas ua rau nyias nyias nyias?
Irregular uterine los ntshav los ntawm PCOS feem ntau yog vim tsis muaj ovulation. Raws li qhov xwm txheej no, lub tsev menyuam tsis muaj zog (endometrium) ua tuab los ntawm cov tshuaj estrogen ntau dhauthiab tsis raug kho los ntawm kev tsim tawm txhua hli ntawm progesterone los ntawm zes qe menyuam uas ib txwm ua raws li ovulation .
Koj puas tuaj yeem khov cov nplaum nplaum nplaum nplaum nplaum?
Yog, koj tuaj yeem khov cov nplaum nplaum nplaum nplaum rau ib ncig ntawm 3 lub hlis. Koj tuaj yeem khov cov nplaum nplaum nplaum nplaum nplaum uas tsis tau ci los yog ci uas txhais tau tias koj tuaj yeem khov cov khoom seem ntawm cov paj npleg.
Thaum twg nyias nyias nyias nyias?
Turnips zus rau cov hauv paus hniav yog thinned thawj zaug thaum cov yub siab li 4 ntiv tesQhov sib nrug ntawm 2 mus rau 6 ntiv tso cai rau cov hauv paus hniav kom loj hlob yam tsis muaj neeg coob coob. Cov yub me me uas tau muab tshem tawm yog kev sib tw thiab tsw thaum maj mam sauteed los yog ntxiv rau cov zaub ntsuab tshiab los yog do kib .
Vim li cas cov khoom tsim tawm ntawm daim nyias nyias?
Yog vim li cas rau kev txhob txwm ua ntawm lub hnab ntim amniotic sac amniotic sac Lub hnab amniotic, feem ntau hu ua lub hnab dej, qee zaum cov daim nyias nyias, yog lub hnab uas lub embryo thiab tom qab fetus tsim hauv amniotesNws yog ib daim nyias nyias tab sis tawv pob tshab ntawm daim nyias nyias uas tuav lub embryo (thiab tom qab fetus) kom txog rau thaum ntxov ua ntej yug.
Nyob rau hauv cov kua-mosaic qauv uas piav txog plasma daim nyias nyias?
Cov kua dej mosaic qauv ntawm cov plasma membrane: Cov kua dej mosaic qauv ntawm cov plasma membrane piav txog cov plasma membrane li ua kua ua ke ntawm phospholipids, cholesterol, thiab proteins… los yog dej-hlub thaj chaw ntawm cov molecules yog nyob rau hauv kev sib cuag nrog cov dej aqueous ob sab hauv thiab sab nraum cell .
