Magnetosomes tuaj yeem yog siv rau lwm daim ntawv thov, piv txwv li, txhawm rau kuaj pom nucleotide polymorphism, uas yog qhov tseem ceeb rau kev kuaj mob xws li mob qog noj ntshav, ntshav siab, lossis ntshav qab zib, cais cov hlwb lossis kuaj DNA (Arakaki li al., 2008). Txhawm rau cais cov hlwb, cov hlaws sib nqus lossis SPION tau raug sim.
Tom qab ntawd, Magnetosomes ua dab tsi?
Lub hom phiaj ntawm Magnetosome Nyob rau hauv lub cell ntawm tag nrho cov magnetotactic kab mob, magnetosomes raug teeb tsa raws li kev txiav txim zoo chains. Cov magnetosome saw tes ua rau lub xovtooj coj tus cwj pwm zoo li motile, cov koob me me uas lub xovtooj sib txuas thiab ua luam dej mus rau kab sib nqus.
Tom qab, lo lus nug yog, qhov twg cov kab mob magnetotactic pom? MB feem ntau yog pom nyob rau hauv cov dej ntiav ib puag ncig uas cov pa oxygen thiab lwm cov tshuaj redox yog kab rov tav stratified. Ntau yam piav Cov kab mob magnetotactic localize ntawm lossis ze rau thaj tsam oxic anoxic transition zone (OATZ)-ib cheeb tsam hauv kab dej uas muaj cov pa oxygen tsawg heev.
Ua kom pom qhov no, hom hlau twg muaj nyob hauv Magnetosomes?
Magnetosomes yog prokaryotic organelles tsim los ntawm magnetotactic cov kab mob uas muaj nanometer-loj magnetite ( Fe 3O4) los yog / thiab greigite ( Fe 3S4) magnetic crystals enveloped los ntawm ib tug lipid bilayer membrane.
Yuav ua li cas ciaj sia kom zoo dua cov kab mob nrog Magnetosomes?
Magnetically taw qhia kab mob uas yog hloov chaw yuav tsum muaj ib qhov zoo vim hais tias magnetic orientation txo peb-dimensional search rau ib-dimensional nrhiav raws li magnetic teb kab, ib inherently ntau npaum txheej txheem (9).

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
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
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
