Compound microscopes nthuav tawm cov ntsiab lus me me thiab cov qauv ntawm cov nroj tsuag, cov pob txha pob txha thiab cov qe ntshav, ib leeg-celled creatures zoo li amoebas, thiab ntau ntxiv. Yuav luag txhua tsev neeg tsev kawm ntawv lossis hobbyist yuav xav tau ib qho 400x ib compound microscope los kawm cov hlwb thiab cov kab mob me me hauv biology thiab life science.
Tom qab ntawd, ib tug kuj yuav nug, hom microscope koj xav pom ib qho amoeba?
Teeb microscopes hla lub teeb los ntawm cov iav slides kom pom cov khoom xws li cov hlwb ntawm qhov loj dua. Teeb microscopes tuaj yeem muaj ib lub qhov muag (monocular) lossis ob lub qhov muag (binocular). Nyob rau hauv thiaj li yuav saib amoeba los yog paramecium, tej zaum koj yuav xav tau qhov loj ntawm tsawg kawg 100X.
Tsis tas li ntawd, koj puas tuaj yeem pom amoeba yam tsis muaj lub tshuab tsom? Tib neeg qhov muag tsis tuaj yeem saib feem ntau cov hlwb tsis muaj kev pab ntawm ib microscope . Txawm li cas los xij, qee qhov loj amoebas thiab cov kab mob, thiab qee lub hlwb hauv cov kab mob sib luag zoo li tib neeg thiab squid, ua tau raug saib tsis muaj kev pab.
Tom qab ntawd, koj yuav txheeb xyuas cov amoebas li cas?
Amoebas yog txheeb xyuas los ntawm lawv lub peev xwm los tsim ib ntus cytoplasmic extensions hu ua pseudopodia, lossis ko taw cuav, los ntawm kev uas lawv txav mus los. Hom kev txav no, hu ua amoeboid txav, yog suav tias yog daim ntawv tseem ceeb tshaj plaws ntawm tsiaj locomotion.
Dab tsi yog amoeba zoo li nyob rau hauv lub microscope?
Amoeba Hauv Microscope . Amoeba yog shapeless (lawv zoo li ib tug loj blob) unicellular kab mob los ntawm genus Protozoa. Txhua amoeba muaj ib los yog ntau lub nuclei thiab ib qho yooj yim contractile vacuole los tswj osmotic equilibrium. Zaub mov ntim los ntawm lub amoeba yog khaws cia thiab zom rau hauv vacuoles.

Dab tsi yog pom meej ntawm 400x magnification?
Ntawm 100x magnification koj yuav pom 2 hli. Ntawm 400x magnification koj tuaj yeem pom 0.45mm, lossis 450 microns. Ntawm 1000x magnification koj tuaj yeem pom 0.180mm, lossis 180 microns
Dab tsi magnification ua haujlwm zoo tshaj plaws rau amoeba?
Txhawm rau saib amoeba lossis paramecium, koj yuav xav tau qhov loj ntawm yam tsawg kawg 100X. Tom qab nyeem cov ntawv txuas saum toj no, koj yuav nkag siab tias tag nrho qhov kev nthuav dav yog kev sib txuas ntawm lub qhov muag (yuav luag 10X) thiab lub hom phiaj lens (feem ntau 4X - 100X)
Koj xav tias dab tsi yog yam uas cuam tshuam rau qhov pom thiab qhov loj ntawm craters thiab ejecta?
Cov yam ntxwv cuam tshuam rau qhov tshwm sim ntawm qhov cuam tshuam craters thiab ejecta yog qhov loj thiab qhov nrawm ntawm lub impactor, thiab geology ntawm lub hom phiaj nto. Nyob rau hauv lub ntiaj teb, qhov cuam tshuam craters tsis tau yooj yim lees paub vim yog huab cua thiab yaig
Dab tsi yog qhov txawv ntawm lub teeb pom kev thiab pom tsis pom?
Tsis muaj qhov sib txawv ntawm lub teeb pom kev thiab pom tsis pom lub teeb xws li xov tooj cua nthwv dej thiab X rays. Lawv yog tag nrho cov electromagnetic tsis txawv nyob rau hauv ib txoj kev xwb: lawv wavelength. Lub teeb ultraviolet, X rays, thiab gamma rays tag nrho muaj luv luv wavelengths tshaj li pom lub teeb
Dab tsi magnification koj xav tau kom pom paramecium?
400x loj Raws li kev sib raug zoo, koj xav tau qhov loj npaum li cas kom pom cov hlwb? 400x ib Tom qab ntawd, lo lus nug yog, koj puas tuaj yeem pom paramecium yam tsis muaj lub tshuab tsom? Qee lub hlwb pom ntawm qhov muag tsis pom Qhov ntawd txhais tau hais tias nyob rau hauv cov xwm txheej zoo, koj tej zaum yuav ua tau saib aameoba proteus, tib neeg qe, thiab a Paramecium tsis muaj siv magnification.
