Kev tsim khoom tseem ceeb. Tag nrho cov thawj productivity, los yog GPP , yog tus nqi ntawm lub hnub ci zog yog ntes nyob rau hauv qab zib molecules thaum lub sij hawm photosynthesis (lub zog ntes ib chav tsev ib chav tsev ib lub sij hawm). Cov neeg tsim khoom xws li cov nroj tsuag siv qee lub zog no rau cov metabolism / cellular respiration thiab qee qhov rau kev loj hlob (tsim ntaub so ntswg).
Tsuas yog li ntawd, NPP thiab GPP yog dab tsi?
Hauv cov khoom noj khoom haus, lub zog khaws cia ntawm qib tsim khoom yog hu ua thawj tsim khoom lag luam (PP). Tag nrho cov khoom lag luam tseem ceeb ( GPP ) yog tus nqi ntawm photosynthesis. Net thawj productivity ( NPP ) yog tus nqi cia ntawm cov organic teeb meem tshwj tsis yog siv rau kev ua pa los ntawm cov nroj tsuag.
Ib sab saum toj no, GPP suav li cas? Gross Primary Productivity ( GPP ) yog tag nrho cov pa roj carbon uas tau kho los ntawm cov kab mob hauv lub sijhawm. Txhawm rau txiav txim siab qhov no rau koj tus qauv, rho tawm lub raj mis tsaus DO los ntawm lub teeb DO qhov tseem ceeb, ces faib nws los ntawm lub sijhawm (feem ntau hauv hnub).
Raws li txoj cai, tag nrho cov khoom tsim tawm yog dab tsi?
Tag nrho cov thawj tsim tawm thiab net Primary Production Gross Primary Production (GPP) yog tus nqi ntawm cov tshuaj siv zog, feem ntau qhia raws li carbon biomass, uas thawj cov neeg tsim khoom tsim nyob rau hauv ib lub sij hawm muab.
Dab tsi yog qhov kev tsim khoom tseem ceeb hauv biology?
Kev tsim khoom tseem ceeb yog ib lo lus siv los piav txog tus nqi uas cov nroj tsuag thiab lwm yam kab mob photosynthetic tsim cov organic tebchaw nyob rau hauv ib tug ecosystem. Muaj ob yam ntawm thawj cov khoom lag luam : Tag nrho kev tsim khoom = tag nrho cov photosynthetic ntau lawm cov organic tebchaw nyob rau hauv ib tug ecosystem.

Dab tsi yog qhov kev tawm tswv yim zoo hauv biology?
Kev tawm tswv yim zoo yog ib txoj hauv kev uas cov khoom kawg ntawm qhov kev txiav txim ua rau ntau qhov kev txiav txim tshwm sim hauv cov lus tawm tswv yim. Nws yog qhov sib txawv nrog cov lus tawm tswv yim tsis zoo, uas yog thaum kawg ntawm qhov kev txiav txim txwv tsis pub qhov kev txiav txim txuas ntxiv mus. Cov txheej txheem no muaj nyob hauv ntau lub tshuab lom neeg
Dab tsi yog proteasome hauv biology?
Proteasome: Ib qho protein degradation 'tshuab' nyob rau hauv lub cell uas zom tau ntau yam proteins rau hauv luv polypeptides thiab amino acids. Proteasome yog nws tus kheej tsim los ntawm cov proteins. Nws yuav tsum tau ATP ua haujlwm. Tib neeg lub cell muaj txog 30,000 proteasomes
Dab tsi yog ethylene hauv biology?
Ethylene. (Science: chemical plant biology) cog kev loj hlob (phytohormone, cog hormone), koom nrog txhawb kev loj hlob, epinasty, txiv hmab txiv ntoo ripening, senescence thiab tawg ntawm dormancy. Nws qhov kev ua tau zoo txuas nrog cov auxin
Dab tsi yog mucor hauv biology?
Mucor yog ib hom kab mob pwm. Pwm yog nyob rau hauv lub nceeg vaj Fungi, thiab lawv yog tsim los ntawm xov zoo li hyphae uas kis tawm los ntawm ib tug pom mycelium. Mucor feem ntau pom nyob rau hauv av, thiab feem ntau hom loj hlob zoo tshaj plaws nyob rau hauv qis kub. Mucor indicus yog cov pwm uas muaj txiaj ntsig tiag tiag
Dab tsi yog pyruvic acid hauv biology?
Txhais. npe. Tsis muaj xim, dej-soluble, organic kua ua los ntawm kev tawg ntawm carbohydrates thiab suab thaj thaum lub sij hawm glycolysis, thiab nrog ib tug tshuaj formula ntawm: CH3COCO2H. Ntxiv. Yog tias muaj cov pa oxygen, pyruvic acid hloov mus rau acetyl coenzyme A uas nkag mus rau hauv txoj kev tsim lub zog, lub voj voog Krebs
