Hauv av , organic teeb meem muaj cov nroj tsuag thiab tsiaj txhu khoom uas yog nyob rau hauv tus txheej txheem ntawm decomposing. Thaum nws tau tag nrho decomposed nws yog hu ua humus. Qhov no humus yog qhov tseem ceeb rau av qauv vim nws tuav ib tug neeg ntxhia hais ua ke nyob rau hauv pawg.
Ua li no, hom organic teeb meem twg pom hauv av?
Av organic teeb meem (SOM) yog organic feem ntawm av , muaj peb yam tseem ceeb xws li cov nroj tsuag me me (tshiab) thiab me me nyob av cov kab mob, decomposing (active) organic teeb meem , thiab ruaj khov organic teeb meem (humus).
Ib tug kuj yuav nug, cov khoom siv organic txhais li cas? Organic teeb meem (los yog cov khoom siv organic ) yog teeb meem uas tau los ntawm cov kab mob uas muaj sia nyob tsis ntev los no. Nws muaj peev xwm lwj, los yog yog cov cov khoom lwj; los yog muaj li ntawm organic tshuaj sib xyaw. Tsis muaj ib tug txhais ntawm organic teeb meem nkaus xwb. Cov organic teeb meem hauv av los ntawm cov nroj tsuag thiab tsiaj txhu.
Dhau li ntawm no, dab tsi yog organic av ua los ntawm?
Organic Av thiab Hloov Kho Lub ntsiab txhais ntawm scientific organic av yog "Ntawm, hais txog, lossis muab los ntawm cov khoom muaj sia." Organic av muaj cov khoom siv cog qoob loo, cov kab mob, kab mob, thiab ntau lwm yam. Av yog muaj li ntawm peb lub ntsiab lus: xuab zeb, av nplaum, thiab silt.
Vim li cas cov khoom siv organic hauv av tseem ceeb?
Organic teeb meem suav nrog tej nroj tsuag lossis tsiaj txhu khoom uas rov qab mus rau lub av thiab mus los ntawm cov txheej txheem decomposition. Ntxiv nrog rau muab cov as-ham thiab chaw nyob rau cov kab mob nyob hauv lub av , organic teeb meem kuj khi av particles rau hauv aggregates thiab txhim kho cov dej tuav peev xwm ntawm av.

Cov khoom twg yog cov piv txwv ntawm cov khoom siv tshuaj xyuas txhua yam uas siv?
Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, piv txwv li, ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2)

Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Cov khoom siv organic yog dab tsi?
Cov khoom siv organic. Organic cov ntaub ntawv tau txhais nyob rau hauv niaj hnub chemistry raws li carbon-raws li cov tebchaw, Ameslikas muab los ntawm cov kab mob nyob tab sis tam sim no suav nrog lab-synthesized versions thiab. [1] Feem ntau yog kev sib txuas ntawm ob peb lub teeb pom kev zoo, tshwj xeeb tshaj yog hydrogen, carbon, nitrogen, thiab oxygen
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
