Txij li lub siab yog Nyob ntawm qhov kub thiab txias, koj yuav tsum ua qhov no rau hauv qhov sib npaug los ntawm kev sib npaug ntawm qhov kub thiab txias hauv degrees Kelvin, uas yog sib npaug ntawm qhov kub thiab txias hauv degrees Celsius ntxiv rau 273. Cov mis rau qhov muaj peev xwm solute (ψs) yog : ψs = iCRT.
Ntawm no, iCRT biology yog dab tsi?
Solute (osmotic) peev xwm (ψs.) = - iCRT . i = Tus naj npawb ntawm cov molecule yuav ua nyob rau hauv dej; rau. NaCl qhov no yuav yog 2; rau sucrose lossis qabzib, tus lej no yog 1. C = Molar concentration.
Kuj Paub, yog dab tsi yog lub mis rau solute peev xwm? Dej peev xwm (Ψ) tau txiav txim siab los ntawm kev coj mus rau hauv tus account ob yam - osmotic (los yog daws ) peev xwm (ΨS) thiab siab peev xwm (ΨP). Cov qauv rau xam dej peev xwm yog Ψ = ΨS + ΨP. Osmotic muaj peev xwm yog ncaj qha proportional rau lub daws concentration.
Hais txog qhov no, C hauv iCRT yog dab tsi?
ψs = - iCRT . i = ionization tas li rau sucrose (= 1.0 vim sucrose tsis ionize hauv dej) C = Molar concentration ntawm qos yaj ywm.
Lub siab muaj peev xwm biology yog dab tsi?
siab muaj peev xwm Symbol Ψ p. Cov khoom ntawm dej peev xwm vim hydrostatic siab uas yog exerted rau dej nyob rau hauv ib lub cell. Hauv cov nroj tsuag turgid nws feem ntau muaj txiaj ntsig zoo vim qhov nkag ntawm cov dej ua rau cov protoplast thawb tawm tsam phab ntsa ntawm tes (saib turgor).

Dab tsi cov tshuaj tiv thaiv sawv cev rau lub cev qhuav dej synthesis?
Nyob rau hauv lub cev qhuav dej synthesis cov tshuaj tiv thaiv (Daim duab), cov hydrogen ntawm ib tug monomer ua ke nrog cov hydroxyl pawg ntawm lwm monomer, tso ib tug molecule ntawm dej. Nyob rau tib lub sijhawm, cov monomers sib koom electrons thiab tsim covalent bonds. Raws li cov monomers ntxiv koom nrog, cov saw hlau ntawm kev rov ua dua monomers tsim ib lub polymer
Qhov twg hauv qab no zoo tshaj plaws sawv cev rau qhov sib npaug molecular rau cov tshuaj tiv thaiv ntawm aqueous ammonia nrog sulfuric acid?
Nqe Lus Nug: Qhov Sib npaug Sib npaug rau Kev Ua Haujlwm Ntawm Aqueous Sulfuric Acid Nrog Aqueous Ammonia yog 2NH3 (aq) + H2SO4 (aq) --> (NH4) 2SO4 (aq) A
SFA sawv cev rau dab tsi ntawm lub cev muaj zog?
Service Factor Amps, los yog S.F.A., sawv cev rau tus nqi tam sim no lub cev muaj zog yuav kos thaum khiav ntawm tag nrho Service Factor. Hauv qhov piv txwv nameplate, S.F.A. yog yim amps ntawm 230 volts. Txuas ntxiv tshaj S.F.A. qhia rau ntawm daim ntawv teev npe tuaj yeem ua lub neej luv luv
Qhov twg electron configuration sawv cev rau ib tug atom nyob rau hauv nws lub hauv av?
Yog li txhua qhov kev teeb tsa hluav taws xob nyob rau hauv uas lub xeem electron (dua, lub valence electron) yog nyob rau hauv lub zog ntau dua orbital, lub caij no tau hais tias nyob rau hauv lub xeev zoo siab. Piv txwv li, yog tias peb saib hauv av hauv lub xeev (electrons nyob rau hauv lub zog qis tshaj plaws uas muaj orbital) ntawm oxygen, lub teeb tsa hluav taws xob yog 1s22s22p4
AP biology sawv cev rau dab tsi?
Advanced Placement Biology (AP Biology lossis AP Bio) yog ib chav kawm Advanced Placement biology thiab kev xeem uas muaj los ntawm Pawg Thawj Saib Xyuas Tsev Kawm Qib Siab hauv Tebchaws Meskas. Rau xyoo kawm ntawv 2012-2013, Pawg Saib Xyuas Tsev Kawm Ntawv Qib Siab tau nthuav tawm cov ntaub ntawv kawm tshiab nrog rau kev tsom mus rau 'kev coj noj coj ua'
