Nitrate ions thiab nitrite ions hloov mus rau nitrous oxide gas thiab nitrogen gas ( N2 ). Cov hauv paus hniav nqus ammonium ions thiab nitrate ions siv los ua cov molecules xws li DNA, amino acids, thiab cov proteins. Organic nitrogen (cov nitrogen hauv DNA, amino acids, proteins) tawg mus rau ammonia, ces ammonium.
Hauv kev hwm rau qhov no, dab tsi yog txheej txheem uas ammonia hloov mus rau nitrite ces mus rau nitrate?
Nitrification yog qhov txheej txheem uas converts ammonia rau nitrite thiab tom qab ntawd mus rau nitrate thiab yog lwm kauj ruam tseem ceeb hauv ntiaj teb no nitrogen voj voog.
Tsis tas li ntawd, nitrogen hloov mus rau ammonia li cas? Kauj ruam 1- Nitrogen Fixation - Cov kab mob tshwj xeeb hloov tus nitrogen gas (N2) rau ammonia (NH3) uas cov nroj tsuag siv tau. Kauj Ruam 2- Nitrification- Nitrification yog txheej txheem uas hloov tus ammonia rau hauv nitrite ions uas cov nroj tsuag tuaj yeem noj hauv cov as-ham.
Ua li no, nitrates hloov mus rau nitrogen li cas?
Denitrification ua tiav cov nitrogen lub voj voog los ntawm hloov nitrate (NO3-) rov qab mus rau gaseous nitrogen ( N 2). Cov kab mob denitrifying yog cov neeg ua haujlwm ntawm cov txheej txheem no. Cov kab mob no siv nitrate es tsis txhob oxygen thaum tau txais lub zog, tso tawm nitrogen gas rau huab cua.
Ob hom kev kho nitrogen yog dab tsi?
Cov ob hom kev kho nitrogen yog: (1) Lub cev Nitrogen Fixation thiab (2) Biological Nitrogen Fixation . Sib nrug los ntawm carbon, hydrogen thiab oxygen, nitrogen yog qhov tseem ceeb tshaj plaws macro-element hauv cov tsiaj muaj sia.

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 ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb
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
Dab tsi yog lub zog tso tawm cov txheej txheem uas rhuav tshem cov molecules loj rau hauv cov me?
Catabolic Reactions. Cov tshuaj tiv thaiv Catabolic rhuav tshem cov organic molecules loj rau hauv cov molecules me, tso tawm lub zog uas muaj nyob rau hauv cov tshuaj bonds
