Archaea , (domain Archaea ), ib pawg ntawm cov kab mob ib leeg-celled prokaryotic (uas yog, cov kab mob uas lawv lub hlwb tsis muaj ib qho txhais nucleus) uas muaj cov yam ntxwv molecular sib cais lawv los ntawm cov kab mob (lwm, ntau pawg ntawm prokaryotes) thiab los ntawm eukaryotes (cov kab mob, nrog rau cov nroj tsuag thiab
Kuj paub, dab tsi yog qhov tshwj xeeb ntawm archaea?
Archaeal hlwb muaj tshwj xeeb Cov khoom sib cais lawv los ntawm ob lub npe, Kab mob thiab Eukaryota. Archaea tau muab faib ua ntau yam phyla paub. Archaea reproduce asexually los ntawm binary fission, fragmentation, los yog budding; tsis zoo li cov kab mob, tsis paub hom kab mob Archaea tsim cov endospores.
koj txhais li cas los ntawm archaea? Plural archaea ua Ib pawg ntawm cov kab mob uas zoo li cov kab mob tab sis yog txawv ntawm lawv nyob rau hauv lawv cov caj ces pleev thiab tej yam ntawm lawv cov qauv ntawm tes, xws li cov muaj pes tsawg leeg ntawm lawv cov phab ntsa cell.
Ntxiv mus, 3 hom Archaea yog dab tsi?
Muaj peb loj paub pawg ntawm Archaebacteria : Methanogens, halophiles, thiab thermophiles. Methanogens yog cov kab mob anaerobic uas tsim methane. Lawv muaj nyob rau hauv cov dej phwj tuaj kho cov nroj tsuag, bogs, thiab cov hnyuv ntawm ruminants. Ancient methanogens yog lub hauv paus ntawm natural gas.
Yuav ua li cas yog ib co piv txwv ntawm archaea kab mob?
Archaea yog unicellular kab mob uas ua rau lub thib peb domain kab mob nyob ntiaj teb.
Qee qhov piv txwv suav nrog:
- Aeropyrum pernix.
- Thermosphaera aggregans.
- Ignisphaera aggregans.
- Sulfolobus hmoov.
- Metallosphaera sedula.
- Staphylothermus marinus.
- Thermoproteus tenax.

Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Dab tsi yog txhais los ntawm lo lus inorganic hauv lub ntsiab lus ntawm cov ntxhia?
Ib txwm tshwm sim, homogeneous inorganic khoom muaj cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv crystalline qauv, xim, thiab hardness. Ib qho khoom siv tsis zoo, xws li calcium, hlau, potassium, sodium, lossis zinc, uas yog qhov tseem ceeb rau kev noj haus ntawm tib neeg, tsiaj txhu, thiab nroj tsuag
Dab tsi yog lub ntsiab lus ntawm kev txo qis hauv biology?
Kev txo qis suav nrog ib nrab ntawm cov tshuaj tiv thaiv uas ib hom tshuaj txo nws cov oxidation naj npawb, feem ntau yog los ntawm kev txais electrons. Ntawm no, oxidation yog qhov poob ntawm hydrogen, thaum txo qis yog qhov nce ntawm hydrogen. Qhov kev txo qhov tseeb tshaj plaws suav nrog cov electrons thiab oxidation tooj
Dab tsi yog lub ntsiab lus ntawm kev xaiv ntuj tsim hauv biology?
Ob lub tswv yim tseem ceeb uas tsav evolution yog kev xaiv ntuj thiab genetic drift. Kev xaiv ntuj yog cov txheej txheem los ntawm cov khoom qub txeeg qub teg ua rau lub cev muaj feem muaj sia nyob thiab yug me nyuam. Keeb kwm tau hais los ntawm Charles Darwin, kev xaiv ntuj yog tus txheej txheem uas ua rau muaj kev hloov pauv ntawm lub cev
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
