Txhua lub nceeg vaj no muaj ntau lub ntsiab lus txhais, tab sis ib qho uas cais qee yam ntawm lawv yog txoj kev uas lawv muab lawv lub zog, lossis lawv lub zog. hom khoom noj khoom haus . Archaebacteria yog cov kab mob microscopic pom nyob rau hauv qhov chaw siab tshaj hauv ntiaj teb. Lawv tau txais lawv khoom noj khoom haus Feem ntau yog los ntawm absorption, photosynthesis, thiab ingestion.
Khaws qhov no hauv kev xav, hom khoom noj khoom haus yog dab tsi?
Autotrophs (los yog Autotrophic Hom Kev Noj Qab Haus Huv ) Cov kab mob uas tuaj yeem ua zaub mov lawv tus kheej los ntawm cov khoom yooj yim xws li carbon dioxide thiab dej hu ua autotrophs. Lawv hom khoom noj khoom haus Nws yog hu ua asautotrophic. Lawv ua qhov no los ntawm cov txheej txheem ntawm photosynthesis.
Tsis tas li ntawd, qhov tseem ceeb ntawm archaea yog dab tsi? Methanogenic archaea ua Ua lub luag haujlwm tseem ceeb hauv cov txheej txheem inecosystems nrog cov kab mob uas tau txais lub zog los ntawm oxidation ntawm methane, ntau yam uas yog cov kab mob, vim tias lawv feem ntau yog ib qho tseem ceeb ntawm methane hauv ib puag ncig thiab tuaj yeem ua lub luag haujlwm asprimary producers.
Ib yam li ntawd, tib neeg nug, yog archaebacteria yog Autotroph lossis Heterotroph?
Teb thiab piav qhia: Archaea tuaj yeem ua tau ob qho tib si autotrophic thiab heterotrophic. Archaea muaj ntau yam metabolic.
Dab tsi yog cov yam ntxwv ntawm archaebacteria?
Archaebacteria Nws muaj lipids hauv lawv cov cellmembranes. Lawv yog tsim los ntawm branched hydrocarbon chains, txuas nrog glycerol los ntawm ether linkages. Txij li thaum cov kab mob no tsis muaj nuclei, cov khoom siv caj ces ntab dawb hauv lub cytoplasm. Lawv muaj ribosomal RNA (rRNA).

Dab tsi yog photosynthesis khoom noj khoom haus?
Photosynthesis yog txheej txheem uas phototrophs hloov lub teeb lub zog rau hauv cov tshuaj siv zog, uas tom qab ntawd yog siv los ua cov haujlwm ntawm tes. Tag nrho cov nroj tsuag ntsuab thiab ob peb lwm yam kab mob autotrophic siv photosynthesis los ua ke cov as-ham los ntawm kev siv carbon dioxide, dej thiab hnub ci
Dab tsi yog cov xim muaj nyob rau hauv daim ntawv qhia kev phom sij rau kev noj qab haus huv hauv NFPA 704?
NFPA 704 pob zeb diamond kos npe siv los tso saib cov ntaub ntawv no muaj plaub ntu xim: xiav, liab, daj, thiab dawb. Txhua ntu yog siv los txheeb xyuas ib pawg sib txawv ntawm qhov muaj peev xwm txaus ntshai. Ntu xiav ntawm NFPA xim code cim qhia txog kev phom sij rau kev noj qab haus huv
Ib puag ncig kev noj qab haus huv lub cev yog dab tsi?
Lub cev ib puag ncig suav nrog av, huab cua, dej, nroj tsuag thiab tsiaj txhu, vaj tse thiab lwm yam kev tsim kho vaj tse, thiab tag nrho cov peev txheej ntuj uas muab peb cov kev xav tau yooj yim thiab lub sijhawm rau kev loj hlob ntawm kev sib raug zoo thiab kev lag luam. Ib puag ncig huv, noj qab nyob zoo yog qhov tseem ceeb rau tib neeg lub cev thiab lub siab lub ntsws
Kev noj zaub mov zoo li cas yog siv los txhim kho kev noj qab haus huv?
Khoom noj khoom haus genomics muab cov txhais tau tias los tsim cov molecular biomarkers thaum ntxov, piv txwv li kev hloov pauv ntawm kev saib xyuas kev noj qab haus huv thiab kev loj hlob ntawm tus kab mob. Cov noob no tej zaum yuav raug siv los ua lub hom phiaj los txheeb xyuas cov khoom noj khoom haus uas muaj peev xwm hloov kho lawv cov kev qhia
Dab tsi yog ob hom kev phom sij uas cuam tshuam rau tib neeg kev noj qab haus huv?
Muaj ntau ntau hom tshuaj lom neeg, xws li neurotoxins, tshuaj tiv thaiv kab mob, tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tua kab mob, co toxins, asthmagens, pneumoconiotic agents, thiab sensitizers. Cov kev phom sij no tuaj yeem ua rau muaj kev pheej hmoo ntawm lub cev thiab / lossis kev noj qab haus huv
