Volatility hlau yog dab tsi?
Nyob rau hauv chemistry, volatility yog ib tug khoom zoo uas piav qhia yuav ua li cas nkag tau ib yam khoom vapourizes. Nyob rau ntawm qhov kub thiab txias, ib yam khoom uas muaj volatility siab yog feem ntau yuav tshwm sim raws li ib tug vapour, hos ib yam khoom uas tsis volatility yog ntau dua yuav ua kua los yog khoom.
PB puas hloov pauv?
The non-volatile hlau lead (Pb) thiab cadmium (Cd) ranged ntawm 0.06 txog 0.64 μg / g thiab 0.002 txog 0.03 μg / g, feem.)
Puas yog zinc volatile?
Vim li cas Zn, Cd thiab Hg softer thiab volatile hlau? Lub d-orbital ntawm Zn, Cd thiab Hg tau puv tag. Vim lawv cov d-orbitals tag nrho, lawv muaj cov hlau tsis muaj zog thiab cov khoom ntim tsawg tshaj plaws, yog li lawv txhua tus tsis hloov pauv hauv qhov xwm txheej.

Dab tsi yog qhov hloov pauv thiab hloov pauv hloov pauv?
Point mutations hloov ib leeg nucleotide. Frameshift kev hloov pauv yog ntxiv lossis tshem tawm ntawm nucleotides uas ua rau muaj kev hloov pauv hauv kev nyeem ntawv. frameshift thiab point mutation yog dab tsi? Ib qho kev hloov pauv cuam tshuam rau ib khub hauv paus.
Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?
Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).
Puas yog jurassic ntiaj teb hloov pauv hloov pauv hloov pauv?

Qhov twg yog qhov kev hloov pauv hloov pauv hloov pauv?
Semiconservative replication piav qhia txog cov txheej txheem ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb. DNA replication tshwm sim ntawm ntau lub hauv paus pib ntawm kev rov ua dua raws DNA qauv strand. Raws li DNA ob chav helix yog unwound by helicase, replication tshwm sim nyias ntawm txhua tus qauv strand nyob rau hauv antiparallel cov lus qhia.
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
