Dej polarity tso cai rau nws kom yaj lwm cov polar tshuaj yooj yim heev. Thaum ib tug polar yam khoom yog muab tso rau hauv dej , qhov zoo kawg ntawm nws cov molecules yog attracted rau qhov tsis zoo kawg ntawm lub dej molecules, thiab vice versa. Nto nro ua rau dej kom clump nyob rau hauv tee dua li kis tawm nyob rau hauv ib tug nyias txheej.
Nyob rau hauv no, yuav ua li cas lub polarity ntawm dej ua rau nws ib tug zoo solvent?
Dej yog a zoo kuab tshuaj vim nws polarity . Qhov loj me me ntawm dej molecules feem ntau tso cai rau ntau yam dej molecules nyob ib puag ncig ib molecule ntawm solute. Ib feem tsis zoo dipoles ntawm cov dej yog attracted rau qhov zoo them cov ntsiab lus ntawm cov solute, thiab vice versa rau qhov zoo dipoles.
Ib tug kuj yuav nug, dab tsi yog qhov tseem ceeb ntawm cov polarity ntawm cov dej? Ntau tseem ceeb , cov polarity ntawm dej Nws yog lub luag haujlwm rau kev ua kom muaj txiaj ntsig zoo rau lwm cov polar molecules, xws li qab zib thiab ionic compounds xws li ntsev. Ionic compounds yaj hauv dej tsim ions. Qhov no yog tseem ceeb nco ntsoov vim feem ntau lom Cov tshuaj tiv thaiv tshwm sim, cov reactants yuav tsum tau yaj hauv dej.
Tsis tas li ntawd, dab tsi yog lub luag haujlwm rau cov tshuaj lom neeg txawv txawv ntawm dej?
Dej molecules yog polar, yog li lawv tsim hydrogen bonds. Qhov no muab dej tshwj xeeb cov khoom , xws li ib tug kuj siab kub point , siab tshwj xeeb kub, cohesion, adhesion thiab ceev.
Cov polarity ntawm cov dej tseem ceeb npaum li cas rau cov lus nug transpiration?
Tag nrho cov roj ntsha molecules yuav yaj hauv dej . Yuav ua li cas yog polarity ntawm cov dej tseem ceeb rau transpiration ? Polarity ua rau cohesion ntawm molecules ntawm dej yog li ntawd lawv rub ib leeg thaum lawv txav mus.

Puas yog nws muaj tseeb tias nyob rau hauv kev thauj mus los ntawm kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog?
Hauv kev thauj mus los passive, kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog. _ Muaj tseeb_ 5. Endocytosis yog ib txoj kev uas ib lub cell membrane nyob ib puag ncig thiab siv cov khoom los ntawm ib puag ncig. Ib daim nyias nyias uas tso cai rau qee cov ntaub ntawv dhau los qhia txog kev xaiv permeability
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Dab tsi nthwv dej zoo li cov cuab yeej ntawm lub teeb ua rau nws hloov kev taw qhia thaum nws txav ntawm ib nrab mus rau lwm qhov?
Refraction
Vim li cas cov qauv ntawm cov dej ua rau nws muaj cov kuab tshuaj zoo?
Dej muaj peev xwm yaj ntau yam khoom sib txawv, uas yog vim li cas nws yog ib qho hnyav hnyav. Cov dej molecules muaj lub ntsiab lus ntawm cov pa oxygen thiab hydrogen atoms - ib sab (hydrogen) muaj qhov zoo hluav taws xob thiab lwm sab (oxygen) muaj qhov tsis zoo
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
