Meiosis cov ntsiab lus
| A | B |
|---|---|
| homologous chromosomes ua ke thiab tsim tetrad | prophase 1 |
| spindle fibers txav homologous chromosomes rau opposite ncej | anaphase 1 |
| Nuclear membrane hloov kho, cytoplasm faib, 4 tus ntxhais cell tsim | telophase & cytokinesis 2 |
| chromosomes kab nyob rau hauv kab zauv, tsis nyob rau hauv homologous khub | metaphase 2 |
Tsis tas li cov lus nug yog, theem twg ntawm mitosis puas cytoplasm faib?
Cytokinesis
Tsis tas li ntawd, dab tsi txheej txheem faib lub cell cytoplasm? Cytokinesis yog lub cev txheej txheem ntawm cell division, qho faib tus cytoplasm ntawm niam txiv cell nyob rau hauv ob lub cell. Nws tshwm sim concurrently nrog ob hom nuclear faib hu ua mitosis thiab meiosis, uas tshwm sim nyob rau hauv cov tsiaj hlwb.
Ua kom pom qhov no, nyob rau theem twg ntawm meiosis puas cytoplasm faib?
telophase
Lub sijhawm twg cytoplasm faib 2 tus ntxhais cell tsim?
cytokinesis

Dab tsi yog ob qhov kev faib loj ntawm cytoplasm?
Kev faib. Lub cytoplasm tuaj yeem muab faib ua ob qhov tseem ceeb: endoplasm (endo-,-plasm) thiab ectoplasm (ecto-,-plasm). Lub endoplasm yog qhov chaw nruab nrab ntawm lub cytoplasm uas muaj cov organelles. Lub ectoplasm yog qhov ntau gel zoo li qhov chaw ntawm lub cytoplasm ntawm ib lub xovtooj ntawm tes
Dab tsi yog 6 theem ntawm kev faib cell?
Nws yog qhov tsis tu ncua ntawm kev loj hlob thiab kev faib tawm uas cov hlwb tau txais hauv lawv lub neej. Muaj rau theem uas lub cell npaj los faib; interphase, prophase, metaphase, anaphase, telophase, thiab cytokinesis. Cov txheej txheem no hu ua
Dab tsi yog theem ntawm Linnaean system ntawm kev faib tawm?
Niaj hnub nimno taxonomic classification system muaj yim theem tseem ceeb (los ntawm feem ntau suav nrog rau feem ntau tshwj xeeb): Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species Identifier
Qhov twg theem ntawm meiosis kuv zoo ib yam li theem piv rau hauv mitosis?
Keyboard Shortcuts rau kev siv Flashcards: qhov twg hauv qab no tsis yog qhov txawv ntawm meiosis? Kev txuas ntawm tus muam kinetochore rau spindle microtubles uas theem ntawm meiosis kuv zoo ib yam li theem piv hauv mitosis? telophase kuv
Ob theem ntawm kev faib cell hauv cov kab mob yog dab tsi?
Prokaryotes (cov kab mob) tau txais kev faib tawm ntawm cov cell hu ua binary fission, qhov twg lawv cov khoom siv caj ces raug cais sib npaug rau hauv ob lub hlwb. Thaum binary fission tej zaum yuav yog txoj kev faib los ntawm feem ntau prokaryotes, muaj lwm yam kev faib, xws li budding, uas tau pom
