Txhais Archaea
(Koj tuaj yeem pom peb lub npe pib nrog cov tsiaj ntawv me, tab sis thaum koj tham txog cov npe tshwj xeeb, cov ntsiab lus yog peev .)
Yog li ntawd, dab tsi yog qhov tseem ceeb ntawm Archaea?
Cov yam ntxwv ntawm archaea
- Cell phab ntsa: yuav luag tag nrho cov kab mob muaj peptidoglycan hauv lawv cov phab ntsa cell; Txawm li cas los xij, archaea thiab eukaryotes tsis muaj peptidoglycan.
- Fatty acids: cov kab mob thiab eukaryotes tsim cov lipids uas muaj cov roj fatty acids txuas los ntawm ester bonds rau ib lub molecule ntawm glycerol.
Ib yam li ntawd, 3 yam ntxwv ntawm Archaea yog dab tsi? Cov yam ntxwv ntawm Archaebacteria paub txog niaj hnub no yog cov no: (1) muaj cov yam ntxwv tRNAs thiab ribosomal RNAs; (2) tsis muaj peptidoglycan cell phab ntsa, nrog rau ntau zaus, hloov los ntawm lub tsho loj proteinaceous; (3) qhov tshwm sim ntawm ether txuas lipids tsim los ntawm phytanyl chains thiab (4) hauv
Ua raws li qhov kev pom no, Archaea muaj dab tsi?
Archaea, (domain Archaea), ib qho ntawm ib pawg ntawm cov kab mob ib leeg-celled prokaryotic (uas yog, cov kab mob uas lawv lub hlwb tsis muaj lub ntsiab lus. nucleus ) uas muaj cov yam ntxwv molecular cais lawv los ntawm cov kab mob (lwm yam, cov pab pawg tseem ceeb ntawm prokaryotes) thiab los ntawm eukaryotes (cov kab mob, nrog rau cov nroj tsuag thiab
Puas yog archaea muaj phab ntsa ntawm tes?
Cell phab ntsa thiab flagella Feem ntau archaea ua (tab sis tsis yog Thermoplasma thiab Ferroplasma) muaj a cell phab ntsa . Tsis zoo li cov kab mob, archaea ua tsis muaj peptidoglycan hauv lawv cell phab ntsa.

Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity

Yuav ua li cas cov xwm txheej yuav tsum tau induce ib tug tam sim no nyob rau hauv ib lub voj ntawm hlau?
Hypothesis: Yuav kom induce ib tug tam sim no nyob rau hauv ib lub voj ntawm hlau, tej yam kev mob yuav tsum tau hais tias muaj ib tug magnetic teb. Qhov no yog vim hais tias thaum ib tug conductor txav los ntawm ib tug magnetic teb, ib tug induced tam sim no yog tsim
Yuav ua li cas cov thawj windings txuas thaum lub transformer yuav tsum tau ua nyob rau hauv ib tug 480 volt system?
Lub transformer muaj qhov polarity rho tawm thaum lub davhlau ya nyob twg H1 nyob ib sab ntawm lub davhlau ya nyob twg X1. Thaum lub 240/480 volt dual thawj tswj transformer yuav tsum tau ua los ntawm ib tug 240 volt system thawj winding yog kev cob cog rua nyob rau hauv parallel. Hauv Delta-connected transformer, theem thiab kab voltages sib npaug
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
