Dab tsi hauv nruab nrab cov qauv loj hlob mus rau lub centrosome, thiab muab kev tiv thaiv rau lub cell ? Microtubules.
Tsis tas li ntawd, dab tsi yog lwm lub npe rau centrosomes uas ntseeg tau tias yog lub luag haujlwm ntawm centrioles?
Lwm lub npe rau centrosome yog "microtubule-organizing center." Cov centrioles muaj nuj nqi raws li compression-resisting girders ntawm cytoskeleton. Peb lub luag haujlwm ntawm phab ntsa cell yog dab tsi?
Qhov thib ob, cov organelles twg qee zaum hu ua ntxhib lossis du nyob ntawm lawv cov tsos hauv electron micrographs? Cov endoplasmic reticulum yog subdivided rau hauv ntxhib thiab du endoplasmic reticulum. Cov npe tshwm sim los ntawm tus morphology pom nyob rau hauv electron microscope cov duab ntawm tus endoplasmic reticulum. Qee qhov chaw ntawm tus endoplasmic reticulum muaj pob, muab nws ib ntxhib tsos . Cov pob yog ribosomes.
Kuj tseem yuav paub, qhov twg ntawm cov haujlwm hauv qab no cuam tshuam nrog cytoskeleton hauv eukaryotic hlwb?
1. Cov cytoskeleton tus kab mob yog lub network ntawm microfilaments, intermediate filaments, thiab microtubules. 2. Cov cytoskeleton tus kab mob muaj ntau yam muaj nuj nqi suav nrog, muab cov duab rau hlwb tsis muaj a cell phab ntsa, tso cai rau cell kev txav mus los, ua rau kev txav ntawm cov organelles hauv lub cev cell , endocytosis, thiab cell kev faib.
cytoskeleton zoo li koj lub cev pob txha li cas?
Nws muab lub cev zoo, kev txhawb nqa, thiab lub zog. Ua li cas a cytoskeleton zoo li koj lub cev pob txha ? Nws muab cov qauv thiab tiv thaiv lub cev tseem ceeb uas muaj nyob hauv nws. Vim nws tuaj yeem cog lus nyiam cov nqaij ntshiv uas muab lub cev zoo, lub zog, thiab ua rau nws sib cais.

Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Koj pom qhov nruab nrab thiab nruab nrab hauv tableau li cas?
Kev sib txuas lus cov ntaub ntawv nrog Tableau los ntawm Ben Jones Qhov nruab nrab (lossis nruab nrab) yog txiav txim siab los ntawm kev suav tag nrho cov txiaj ntsig hauv cov ntaub ntawv teev thiab faib los ntawm tus lej ntawm qhov tseem ceeb. Qhov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teev nyob rau hauv uas qhov tseem ceeb tau muab tso rau hauv kev txiav txim ntawm qhov loj
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
Koj ua li cas sib npaug redox cov tshuaj tiv thaiv hauv acidic thiab nruab nrab nruab nrab?
Acid Conditions Solution. Kauj Ruam 1: Sib cais ib nrab cov lus teb. Kauj Ruam 2: Ntsuas cov ntsiab lus uas tsis yog O thiab H. Kauj Ruam 3: Ntxiv H2O kom sib npaug ntawm cov pa. Kauj Ruam 4: Sib npaug hydrogen los ntawm kev ntxiv protons (H +). Kauj Ruam 5: Ntsuas tus nqi ntawm txhua qhov sib npaug nrog electrons. Kauj Ruam 6: Ntsuas cov tshuaj tiv thaiv kom cov electrons sib npaug
