Txhua tus ntawm koj hlwb zoo li lub Hoobkas me me. Nyob rau hauv nruab nrab ntawm lub cell yog lub nucleus, 'tus thawj tswj chaw ua haujlwm'. Lub nucleus muaj ib daim qauv ntawm koj cov noob, cov lus qhia ua cov proteins. Sab hauv lwm compartments, lub cell tsim lub zog, tshem tawm cov khib nyiab, thiab ua rau cov molecules nws xav tau kom muaj sia nyob, ua haujlwm thiab loj hlob.
Kuj paub, dab tsi nyob hauv cov hlwb?
Qee qhov eukaryotic hlwb (cog hlwb thiab fungal hlwb ) kuj muaj ib cell phab ntsa. Hauv lub cell yog thaj tsam cytoplasmic uas muaj cov genome (DNA), ribosomes thiab ntau hom kev suav nrog. Cov khoom siv noob caj noob ces muaj pub dawb nyob hauv cytoplasm.
Cov hlwb ua haujlwm li cas hauv tib neeg lub cev? Txhua cell hauv koj lub cev xav tau oxygen los pab nws metabolize (hlawv) cov as-ham tso tawm los ntawm cov zaub mov rau lub zog. Cells uas ua tib txoj hauj lwm ua ke ua ke los tsim lub cev cov ntaub so ntswg, xws li cov leeg, tawv nqaij, lossis cov pob txha. Pawg sib txawv ntawm hlwb ua kom lub cev hauv koj lub cev lub cev , xws li koj lub siab, lub siab, lossis lub ntsws.
Ua li no, puas muaj cov hlwb hauv cov hlwb?
Lawv me me, thiab lawv DNA yog ncig thiab ntab dawb sab hauv tus hlwb . Tag nrho cov kab mob yog prokaryotic hlwb . Lawv loj dua, thiab lawv DNA yog npaj nyob rau hauv linear chromo-somes thiab khaws cia sab hauv ib nucle. Eukaryotic hlwb muaj qee cov organelles uas prokaryotic hlwb tsis muaj zoo li mitochondria.
Qhov tsawg tshaj plaws ntawm lub neej yog dab tsi?
cell

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Yuav ua li cas feem ntau yuav tshwm sim yog tias cov ribosomes hauv lub cell tsis ua haujlwm?
Ribosomes yog organelles uas tsim cov proteins. Cells siv cov protein los ua cov haujlwm tseem ceeb xws li kho cov cellular puas thiab coj cov txheej txheem tshuaj. Yog tias tsis muaj cov ribosomes no, cov hlwb yuav tsis tuaj yeem tsim cov protein thiab yuav tsis tuaj yeem ua haujlwm zoo
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
