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 tsis muaj cov no cov ribosomes , hlwb yuav tsis tuaj yeem tsim cov protein thiab yuav tsis muaj peev xwm muaj nuj nqi kom raug.
Hauv qhov no, yuav ua li cas yog tias lub cell tsis muaj ribosomes?
Ribosomes yog tsim cov protein rau cov hlwb . Yog li yog tus cell tsis muaj ribosomes lawv yuav tsis muaj peev xwm tsim cov protein rau lwm tus hlwb . Nws yuav ua rau hlwb kom tsis txhob ua haujlwm. Yog tsis muaj cov ribosomes hauv cell ces nyob ntawd yuav tsis muaj MRNA.
Ib yam li ntawd, lub cell puas tuaj yeem muaj sia nyob tsis muaj ribosomes? Cells muaj sia nyob tsis muaj ribosomes , tab sis lawv yuav ua rau muaj kev puas tsuaj thiab tsis tuaj yeem rov ua dua lossis cov khoom siv tag nrho ntawm cov protein uas lawv xav tau. Cov ribosome Nws yog ib qho tsim nyog yuav tsum muaj peev xwm ua cov protein txhais lus los ntawm RNA.
Tsis tas li ntawd, dab tsi yuav tshwm sim yog tias cov ribosomes ntawm lub xovtooj tau raug puas tsuaj thiab tsis ua haujlwm?
Cov cell yuav poob qauv thiab cov duab. Cell kev loj hlob thiab kho yuav qeeb los yog nres . Cell pov tseg yuav tsis raug ua tiav lawm.
Yuav ua li cas yog hais tias ib tug cell tsis muaj organelle?
Yog lub nucleus tsis muaj nyob, lub cell yuav tsis muaj kev taw qhia thiab cov nucleolus, uas nyob rau hauv lub nucleus, yuav tsis muaj peev xwm tsim ribosomes. Yog tus cell membrane ua ploj mus , cov cell yuav tiv thaiv. Txhua yam yuav coj mus rau txoj kev tuag cell . Yuav ua li cas tshwm sim yog cell tau tsis muaj organelles ?

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 yog tias dej sib cais tsis tshwm sim thaum lub sij hawm photosynthesis?
Cov chlorophyll molecule sab laug yam tsis muaj hluav taws xob tuaj yeem nqa cov hluav taws xob los ntawm dej faib cov dej rau hauv Hydrogen ions thiab oxygen gas. Qhov no yog vim li cas photosynthesis tso pa oxygen rau hauv huab cua. Lub ntsiab lus ntawm lub teeb pom kev yog ua kom muaj ntau ntawm NADPH thiab ATP
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
Qhov txheej twg yog huab cua tshwm sim feem ntau tshwm sim?
Troposphere. Lub troposphere (los ntawm Greek: tropein - hloov, ncig lossis sib xyaw) yog txheej qis tshaj plaws ntawm lub ntiaj teb huab cua. Feem ntau ntawm huab cua phenomena, systems, convection, turbulence thiab huab tshwm sim nyob rau hauv no txheej, tab sis tej zaum yuav mus rau hauv lub qis feem ntawm thestratosphere
Qhov twg ntawm cov ntsiab lus hauv qab no feem ntau pom nyob rau hauv feem ntau cov chiv?
Cov tshuaj chiv niaj hnub suav nrog ib lossis ntau tshaj ntawm peb lub ntsiab lus tseem ceeb tshaj plaws hauv cov zaub mov noj: nitrogen, phosphorus, thiab potassium. Qhov tseem ceeb thib ob yog cov ntsiab lus sulfur, magnesium, thiab calcium
