| #1 | Qhov twg gas ua 78 feem pua ntawm peb huab cua tab sis tuaj yeem siv los ntawm cov nroj tsuag tsuas yog thaum hloov los ntawm cov kab mob ua ntej? | nitrogen |
| #4 | Dab tsi yog lub pas dej loj ntawm nitrogen uas siv tsis tau los ntawm cov kab mob feem ntau? | tus huab cua |
Yog li ntawd, dab tsi yog qhov loj tshaj plaws reservoir ntawm unusable nitrogen?
Kev piav qhia: Huab cua Muaj ntau cov pa roj, nitrogen yog 78%. Yog li qhov loj tshaj plaws nitrogen reservoir nyob rau hauv lub ntiaj teb yog huab cua.
Ib tug kuj tseem nug, dab tsi yog qhov kawg ntawm lub zog rau yuav luag txhua yam kab mob tshwj tsis yog cov neeg nyob sib sib zog nqus hauv dej hiav txwv ze ntawm lub qhov cua sov? Cov qhov kawg yuav yog lub hnub.
Ib yam li ntawd, koj tuaj yeem nug, qhov twg hauv qab no yog lub pas dej loj tshaj plaws rau cov pa roj carbon?
Cov dej hiav txwv yog lub ntiaj teb loj tshaj plaws carbon reservoir. Cov dej hiav txwv sib sib zog nqus muaj 36,000 gigatons ntawm carbon, thaum cov dej saum npoo muaj 1,020 gigatons. Cov huab cua thiab dej hiav txwv raug kaw nyob rau hauv ib tug symbiotic carbon exchange system.
Koj yuav nrhiav tau cov kab mob nitrogen kho qhov twg?
Nroj tsuag ntawm tsev neeg pea, hu ua legumes, yog qee yam ntawm feem ntau tseem ceeb hosts rau nitrogen - kho cov kab mob , tab sis ib tug xov tooj ntawm lwm cov nroj tsuag kuj muaj peev xwm harbor cov pab tau kab mob . Lwm yam nitrogen - kho cov kab mob yog dawb-nyob thiab tsis xav tau ib tug tswv tsev. Lawv feem ntau pom nyob rau hauv av los yog nyob rau hauv cov dej ib puag ncig.

Dab tsi ntawm cov organic molecule feem ntau yog siv los ua lub zog rau cov hlwb?
Adenosine 5'-triphosphate, lossis ATP, yog cov khoom siv hluav taws xob ntau tshaj plaws hauv cov hlwb. Cov molecule no yog tsim los ntawm nitrogen puag (adenine), ribose qab zib, thiab peb pawg phosphate. Lo lus adenosine yog hais txog adenine ntxiv rau ribose qab zib
Cov kab mob dab tsi los yog cov ntaub so ntswg feem ntau khaws cia ua pob txha?
Lub cev pob txha muaj xws li khaws cia seem ntawm cov kab mob (piv txwv li khov, ziab, petrification, permineralization, kab mob thiab algea). Whereas cov pob txha pob txha yog cov cim qhia tsis ncaj ntawm lub neej uas muab pov thawj ntawm lub cev muaj nyob (piv txwv li hneev taw, burrows, txoj kev thiab lwm yam pov thawj ntawm lub neej txheej txheem)
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Hom molecules twg feem ntau yog siv los ntawm cov kab mob rau quorum sensing?
Cov kab mob Gram-negative thiab Gram-positive siv hom kev sib txuas lus no, txawm hais tias cov teeb liab molecules (auto-inducers) siv los ntawm lawv txawv ntawm ob pawg: Gram-negative bacteria siv feem ntau N-acyl homoserine lacton (AHL) molecules (autoinducer- 1, AI-1) thaum cov kab mob Gram-zoo siv feem ntau peptides (
