Dab tsi yog qhov txheej txheem uas yog xav tias tsim kom muaj feem ntau cov magmas ? Feem ntau granite magma tej zaum daim ntawv thaum kub basaltic magma pas dej ua daig vim hais tias ntawm kuj zoo kawg ceev, hauv qab no lub continental ua kiav txhab.
Nyob rau hauv no, dab tsi txheej txheem generates feem ntau granite magmas?
Ib lub pas dej basaltic ntawm magma ua cuab nyob rau hauv qab teb chaws crust thiab ib nrab melts no silica-nplua nuj crust rau hauv ib granite magma.
Tom qab, lo lus nug yog, yuav ua li cas yog granite magma tsim? tiam. Granitic los yog rhyolitic, magmas thiab andesitic magmas yog tsim los ntawm convergent phaj ciam teb qhov twg dej hiav txwv lithosphere (lub txheej txheej ntawm lub ntiaj teb no muaj li ntawm lub crust thiab sab sauv mantle) yog subducted thiaj li hais tias nws ntug yog positioned nyob rau hauv lub ntug ntawm lub continental phaj los yog …
Ib tug kuj yuav nug, cov txheej txheem twg yog xav tias tus tsim feem ntau felsic granite magmas?
Felsic ( granite ) magma Cov ntaub ntawv los ntawm ib nrab yaj ntawm continental crust, uas muaj cov dej yaj. Dissolved dej ntsiab lus nyob rau hauv a magma txo nws cov melting kub nrog nce siab (dej molecules yuav inhibit lub silicate tetrahedra los ntawm kev sib cog lus).
Dab tsi yog qhov txawv ntawm basaltic thiab granite magma?
Igneous pob zeb yog tsim los ntawm crystallisation ntawm a magma . Cov qhov sib txawv ntawm granites thiab basalts yog nyob rau hauv cov ntsiab lus silica thiab lawv cov nqi cua txias. A basalt yog hais txog 53% SiO2, whereas granite yog 73%. Intrusive, maj mam txias hauv lub crust.

Dab tsi yog cov txheej txheem uas tsim cov ntawv luam tshiab ntawm cov kab mob caj ces?
Cov txheej txheem ntawm DNA replication tsim ib daim qauv tshiab ntawm cov kab mob cov ntaub ntawv caj ces kom dhau mus rau lub cell tshiab. Dawb ntab nucleotides yog txuam nrog lawv cov lus qhuas los ntawm ib qho enzyme hu ua polymerase. Cov no yog 'lub tsev.' Lawv sib sau ua ke DNA tshiab strand nrog txhua tus qub strands
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?
Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud
Cov txheej txheem dab tsi uas tus kws tshawb fawb siv los tsim ntau cov ntawv luam ntawm DNA xav tau sau rau hauv daim ntawv dawb paug 1?
Molecular Cloning. Cloning tso cai rau tsim ntau cov ntawv luam ntawm cov noob, qhia cov noob, thiab kawm txog cov noob tshwj xeeb. Yuav kom tau txais cov DNA tawg rau hauv cov kab mob hauv cov kab mob hauv daim ntawv uas yuav tau theej lossis nthuav tawm, cov khoom tawg yog thawj zaug tso rau hauv plasmid
Cov txheej txheem twg yog txheej txheem endothermic?
Cov txheej txheem endothermic yog ib qho txheej txheem uas xav tau lossis nqus lub zog los ntawm nws qhov chaw nyob ib puag ncig, feem ntau yog ua kom sov. Nws yuav yog cov txheej txheem tshuaj, xws li dissolving ammonium nitrate hauv dej, lossis cov txheej txheem ntawm lub cev, xws li melting ntawm cov dej khov nab kuab
