Mineralization (Soil Science) Mineralization yog qhov opposite ntawm immobilization . Mineralization nce bioavailability ntawm cov as-ham uas nyob rau hauv decomposing organic tebchaw, tshwj xeeb tshaj yog vim hais tias ntawm lawv cov ntau, nitrogen, phosphorus, thiab sulfur.
Tsis tas li ntawd, cov txheej txheem ntawm mineralization yog dab tsi?
Hauv biology, mineralization hais txog a txheej txheem qhov twg cov tshuaj inorganic precipitates hauv cov organic matrix. Qhov no tej zaum yuav yog vim ib txwm lom txheej txheem uas tshwm sim thaum lub neej ntawm cov kab mob xws li tsim cov pob txha, qe plhaub, cov hniav, coral, thiab lwm yam exoskeletons.
Tsis tas li ntawd, dab tsi yog nutrient immobilization? Immobilization yog tus txheej txheem rov qab ntawm mineralization, qhov twg cov as-ham yog hloov los ntawm inorganic mus rau cov ntaub ntawv organic (piv txwv li coj los ntawm cov av microbes thiab incorporated rau hauv lawv cov hlwb), ua rau lawv tsis muaj rau cov nroj tsuag.
Tom qab, lo lus nug yog, dab tsi yog cov txheej txheem ntawm mineralization nyob rau hauv nutrient cycling?
Mineralization yog cov txheej txheem los ntawm cov microbes decompose organic N los ntawm manure, organic teeb meem thiab qoob loo residue rau ammonium. Vim nws yog ib qho kev lom neeg txheej txheem , tus nqi mineralization sib txawv nrog av kub, noo noo thiab tus nqi ntawm oxygen nyob rau hauv cov av (aeration).
Dab tsi yog mineralization nyob rau hauv lub voj voog nitrogen?
TSAB NTAWV. Nitrogen mineralization yog cov txheej txheem uas cov organic N hloov mus rau cov nroj tsuag-muaj cov ntaub ntawv inorganic. Cov av tsis tu ncua hloov nrog cov khib nyiab organic yuav khaws cov organic N kom txog thaum lawv mus txog qhov chaw nyob ruaj khov, lub tswv yim muaj txiaj ntsig zoo rau kev npaj N tswj cov tswv yim.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
