Anaphase Hauv Microscope
Yog koj saib ntxov anaphase siv a microscope , koj yuav pom cov chromosomes meej cais ua ob pawg. Yog koj saib lig anaphase , cov pab pawg ntawm chromosomes yuav nyob rau sab nraud ntawm tes.
Ib yam li ntawd, koj tuaj yeem nug, ua li cas koj txheeb xyuas anaphase?
Anaphase Hauv Microscope Yog tias koj saib lig anaphase , cov pab pawg ntawm chromosomes yuav nyob rau sab nraud ntawm tes. Koj tuaj yeem pom qhov pib ntawm lub cell membrane tshiab ua rau hauv nruab nrab ntawm tes ntawm cov spindle fibers.
Kuj Paub, koj pom cov chromosomes nyob rau hauv lub microscope li cas? Tsuas yog ua ntej cov hlwb pib faib, cov chromosomes ua pom. Cytogeneticists stain lub dividing nucleus thiab saib lawv hauv qab siab zog microscopes los tshuaj xyuas cov pom no chromosomes . Lawv kab lawv thiab txheeb cov no chromosomes rau hauv ntau hom. Tag nrho cov chromosomes nyob rau hauv tib neeg cell hu ua karyotpe.
Yog li ntawd, dab tsi magnification koj xav pom mitosis?
Qauv: Whitefish Magnification: 10x ib / 40x ib Tom qab mitosis lub cell faib ua ob. Saib rau "pinching-in" hauv nruab nrab ntawm ob lub hlwb - qhov no yog qhov cleavage furrow. Cells tom kawg ntawm telophase yuav pib cytokinesis.
Lub hom phiaj ntawm anaphase yog dab tsi?
Anaphase yog ib theem tseem ceeb heev ntawm kev faib cell. Nws xyuas kom meej tias duplicated chromosomes, los yog tus muam chromatids, cais ua ob pawg sib npaug. Qhov kev sib cais ntawm chromosomes no hu ua disjunction. Txhua txheej ntawm chromosomes yuav dhau los ua ib feem ntawm lub cell tshiab.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Yuav ua li cas resistors coj nyob rau hauv series thiab nyob rau hauv parallel?
Txhua tus resistor nyob rau hauv ib tug series Circuit Court muaj tib tus nqi ntawm tam sim no ntws los ntawm nws. Txhua tus resistor nyob rau hauv ib qho hluav taws xob sib txuas muaj tib qhov hluav taws xob tag nrho ntawm qhov siv rau nws. Qhov tam sim no ntws los ntawm txhua tus resistor nyob rau hauv ib qho kev sib txuas sib txuas sib txawv, nyob ntawm qhov tsis kam
Dab tsi yog qhov zoo ntawm electron microscope thiab lub teeb microscope?
Electron microscopes muaj qee qhov zoo ntawm optical microscopes: Qhov zoo tshaj plaws yog tias lawv muaj kev daws teeb meem siab dua thiab yog li tseem muaj peev xwm ua kom muaj qhov loj dua (txog 2 lab lub sijhawm). Lub teeb microscopes tuaj yeem pom qhov muaj txiaj ntsig zoo tsuas yog mus txog 1000-2000 zaug
Dab tsi yog lub hauv paus ntawm illumination nyob rau hauv electron microscope?
Nyob rau hauv kis tau tus mob electron microscope (TEM), lub hauv paus ntawm illumination yog ib tug beam ntawm electrons ntawm luv luv wavelength, tawm los ntawm ib tug tungsten filament nyob rau sab saum toj ntawm ib tug cylindrical kem ntawm txog 2 m siab. Tag nrho cov kab ke kho qhov muag ntawm lub tshuab microscope yog kaw hauv lub tshuab nqus tsev
Yuav ua li cas yog ib co qauv nyob rau hauv landforms nyob rau hauv lub ntiaj teb no?
Cov txheej txheem ntawm lub cev no ua rau cov roob, tiaj, toj, thiab toj siab, plaub hom av loj. Phaj tectonics tuaj yeem tsim cov roob thiab toj roob hauv pes thaum yaig tuaj yeem hnav cov av los tsim cov hav thiab hav zoov
