Magnetotactic kab mob (los yog MTB) yog ib pawg polyphyletic ntawm kab mob uas orient lawv tus kheej nrog rau Sib nqus cov kab ntawm lub ntiaj teb Sib nqus teb. Txhawm rau ua txoj haujlwm no, cov no kab mob muaj organelles hu ua magnetosomes uas muaj Sib nqus siv lead ua.
Ib yam li ntawd, cov kab mob Magnetotactic puas hnov magnetic teb li cas?
Cov kab mob Magnetotactic ua ke Sib nqus hlau nanominerals, uas ua hauj lwm raws li me me compasss uas tso cai rau cov microbes rau navigate siv lub ntiaj teb geomagnetic teb . Ntawm no yog ib qho khoom siv los yog cov khoom sib xyaw ua haujlwm raws li kev txo cov reagent thiab pub cov khoom siv hluav taws xob rau Fe3+.
Tsis tas li ntawd, tag nrho cov hlau yog Magnetic? Sib nqus cov ntaub ntawv yeej ib txwm ua los ntawm hlau, tab sis tsis yog tag nrho cov hlau yog Sib nqus . Hlau yog Sib nqus , yog li tej hlau nrog hlau nyob rau hauv nws yuav tau attracted rau ib hlau nplaum . Cov hlau muaj hlau, yog li daim ntawv hlau steel yuav raug nyiam rau a hlau nplaum ib yam nkaus. Feem ntau lwm yam hlau Piv txwv li, aluminium, tooj liab thiab kub, tsis yog Sib nqus.
Tsis tas li ntawd, Magnetosomes coj zoo li hlau nplaum li cas?
Magnetosomes muaj ib tug nano-sized crystal ntawm ib tug hlau nplaum hlau ntxhia uas yog enveloped los ntawm ib tug lipid bilayer membrane. Cov magnetosome chain ua rau lub cell coj zoo li ib tug motile, me me compass koob qhov twg lub cell dlhos thiab ua luam dej thaum uas tig mus rau magnetic teb kab.
Dab tsi yog hlau yog hlau nplaum?
Cov hlau feem ntau siv rau cov hlau nplaum ruaj khov yog hlau , npib tsib xee , cobalt thiab qee cov alloys ntawm cov hlau tsis tshua muaj hauv ntiaj teb. Muaj ob hom hlau nplaum ruaj khov: cov los ntawm "nyuaj" hlau nplaum cov ntaub ntawv thiab cov los ntawm "mos" magnetic cov ntaub ntawv . "Hard" sib nqus hlau zoo li nyob ruaj khov nyob rau lub sijhawm ntev.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Cov kab mob puas kis cov kab mob eukaryotic?
Ib lub cell uas muaj kab mob ua rau cov kab mob kis tau ntau dua thiab cov khoom siv caj ces es tsis yog nws cov khoom qub. Qee cov kab mob yuav nyob twj ywm hauv cov tswv tsev rau lub sijhawm ntev, ua rau tsis muaj kev hloov pauv hauv lawv cov tswv tsev (ib theem hu ua lysogenic theem). Cov kab mob ua rau muaj ntau yam kab mob hauv eukaryotes
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
Puas yog cov kab mob unicellular kab mob?
Tus Kab Mob Qhov Twg Zoo? Cov kab mob tsis raug cais raws li cov hlwb thiab yog li tsis yog unicellular lossis multicellular kab mob. Cov kab mob muaj cov genomeshat muaj xws li DNA lossis RNA, thiab muaj cov piv txwv ntawm cov kab mob uas yog ob leeg-stranded orsingle-stranded
Cov kab mob puas yog ib hom kab mob ntawm tes?
Teb thiab piav qhia: Cov kab mob no tsis suav tias yog cov cell nyob thiab yog li ntawd tsis yog ib leeg-celled lossis ntau-celled. Lawv tsuas yog suav hais tias yog cov plhaub protein
