Nroj tsuag - Nroj tsuag tsim feem ntau ntawm cov oxygen peb ua pa ntawm ib txheej txheem hu ua photosynthesis. Hauv no txheej txheem cov nroj tsuag siv carbon dioxide, hnub ci, thiab dej los tsim lub zog. Hauv txheej txheem lawv kuj tsim oxygen uas lawv tso rau saum huab cua.
Yog li ntawd, cov ntoo tsim cov pa oxygen yog dab tsi?
Ntoo tso tawm oxygen thaum lawv siv lub zog los ntawm lub hnub ci los ua cov piam thaj los ntawm carbon dioxide thiab dej. Nws yuav siv rau 6 molecules ntawm CO2 rau tsim tawm Ib qho molecule ntawm qabzib los ntawm photosynthesis, thiab rau lub molecules ntawm oxygen raug tso tawm raws li cov khoom lag luam.
Kuj Paub, cov ntoo twg tsim cov pa oxygen ntau tshaj?
- Pines yog nyob rau hauv qab ntawm daim ntawv teev npe nyob rau hauv cov nqe lus ntawm oxygen tso tawm vim hais tias lawv muaj ib tug tsawg Leaf Area Index.
- Oak thiab aspen yog nruab nrab ntawm cov ntsiab lus ntawm cov pa tawm.
- Douglas-fir, spruce, tseeb fir, beech, thiab maple yog nyob rau sab saum toj ntawm daim ntawv rau kev tso pa oxygen.
Kuj paub, cov ntoo yog cov tsim cov pa oxygen?
Ntoo tsis txhob exhale xwb oxygen -lawv kuj haus nws hauv cov txheej txheem hu ua cellular respiration, qhov twg lawv hloov cov suab thaj uas lawv amass thaum nruab hnub rau lub zog, siv oxygen kom muaj zog ntawm cov txheej txheem. Yog li thaum hmo ntuj thaum tsis muaj hnub nyob ib puag ncig rau photosynthesis, lawv nyob net absorbers ntawm oxygen.
Yuav ua li cas cov ntoo hloov co2 rau hauv oxygen?
Nroj tsuag hloov carbon dioxide thiab dej rau hauv qab zib thiab oxygen los ntawm cov txheej txheem ntawm photosynthesis. Nroj tsuag nqus carbon dioxide los ntawm huab cua thaum lub sij hawm photosynthesis. Ib qho me me ntawm carbon dioxide yog tso tawm thaum nplooj ua pa (siv ntawm oxygen ), tab sis nws yog sai sai reabsorbed thaum lub sij hawm photosynthesis.

Cov txheej txheem ntawm kev tsim cov kev daws teeb meem yog dab tsi?
Kev daws yog tsim thaum ib yam khoom hu ua thesolute 'dissolves' rau hauv lwm yam khoom hu ua hnyav.Dissolving yog thaum lub solute tawg los ntawm ib tug loj siv lead ua ntawm molecules mus rau ntau me me los yog ib tug molecules. Lawv ua qhov no los ntawm rub tawm cov ions thiab tom qab ntawd ncig cov ntsev molecules
Dab tsi yog cov txheej txheem tsim nyog rau kev ntxuav cov cuvettes?
Ua ntej siv, cuvettes yuav tsum tau ntxuav kom tshem tawm cov seem seem. Yog tias cov cuvettes zoo li huv si, tsuas yog yaug ob peb zaug nrog dej distilled, tom qab ntawd ib zaug nrog acetone (kom tsis txhob muaj dej) thiab tawm mus rau huab cua qhuav nyob rau hauv txoj hauj lwm inverted (xws li ntawm cov ntaub so ntswg) ua ntej siv
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
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 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
