Stratovolcanoes
Ib yam li ntawd, tib neeg nug, hom magma pom nyob rau ntawm thaj chaw sib cais?
Feem ntau eruptions pib ntawm qhov ua siab tshaj thiab rift aav ntawm Hualalai, Maunaloa, thiab Kīlauea. Rift aav yog thaj chaw uas lub roob hluav taws nyob kev rifting los yog sib cais. Pob zeb hauv a rift tsam muaj ntau cov kab nrib pleb thiab kuj tsis muaj zog, thiab yog li nws yog qhov yooj yim tshaj rau magma kom nws txoj kev mus rau saum npoo los ntawm cov no rift aav.
Tom qab ntawd, lo lus nug yog, hom hluav taws kub dab tsi tshwm sim ntawm thaj tsam sib txawv? Magma muaj pes tsawg leeg txiav txim siab ob hom eruption thiab volcano hom. Composite volcanoes muaj nyob rau hauv convergent ciam teb. Shield volcanoes yog tsim nyob rau hauv divergent phaj ciam teb thiab intraplate. Cinder cones yog ua los ntawm cov khoom me me ntawm ntau hom kev sib xyaw feem ntau los ntawm ib qho kev tawg.
Tib neeg kuj nug tias, hom ciam teb yog thaj tsam li cas?
sib txawv ciam teb
Qhov chaw tectonic feem ntau yog volcanoes txuam nrog?
Volcanoes feem ntau muaj nyob rau hauv cov geologically active ciam teb. Ob hom phaj ciam teb uas feem ntau yuav tsim volcanic kev ua ub no yog divergent phaj ciam teb thiab convergent phaj ciam teb. Ntawm ib thaj tsam sib txawv, daim phiaj tectonic txav sib nrug ntawm ib leeg.

Dab tsi yog cov xim muaj nyob rau hauv daim ntawv qhia kev phom sij rau kev noj qab haus huv hauv NFPA 704?
NFPA 704 pob zeb diamond kos npe siv los tso saib cov ntaub ntawv no muaj plaub ntu xim: xiav, liab, daj, thiab dawb. Txhua ntu yog siv los txheeb xyuas ib pawg sib txawv ntawm qhov muaj peev xwm txaus ntshai. Ntu xiav ntawm NFPA xim code cim qhia txog kev phom sij rau kev noj qab haus huv
Dab tsi ntawm cov hauv qab no muaj nyob rau hauv cov tsiaj hlwb tab sis tsis yog cov nroj tsuag?
Mitochondria, Cell Phab ntsa, Cell membrane, Chloroplast, Cytoplasm, Vacuole. Lub cell phab ntsa, chloroplasts thiab vacuole muaj nyob rau hauv cov nroj tsuag cell es tsis yog tsiaj hlwb
Yuav ua li cas cov ntaub ntawv nyob rau hauv cov cheeb tsam uas oceanic daim hlau diverge thiab tshiab seafloor yog tsim abyssal plains continental txee continental txoj kab nqes mid hiav txwv ridge?
Lub continental txoj kab nqes thiab nce yog hloov pauv ntawm crustal hom, thiab lub abyssal plain yog underlain los ntawm mafic oceanic crust. Oceanic ridges yog diverging phaj ciam teb qhov twg dej hiav txwv lithosphere tshiab tsim thiab dej hiav txwv trenches yog converging phaj ciam teb uas dej hiav txwv lithosphere yog subducted
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
Nyob rau hauv dab tsi organelle yog pyruvate oxidation nqa tawm nyob rau hauv ib lub cell?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis nyob rau hauv lub cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv lub mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
