Mitochondria tau pom sab hauv ntawm koj lub hlwb, nrog rau cov hlwb ntawm cov nroj tsuag. Lawv hloov tus zog khaws cia rau hauv molecules los ntawm broccoli (los yog lwm yam roj molecules) rau hauv ib daim ntawv lub cell tuaj yeem siv.
Ntawm no, cov organelle twg hloov cov tshuaj zog hauv cov zaub mov rau hauv daim ntawv uas cov hlwb siv tau?
mitochondria
Tom qab ntawd, lo lus nug yog, uas cov organelles puv nrog enzymes? Lysosomes : Lysosomes yog cov kab mob sib txuas uas muaj cov enzymes digestive uas zom cov protein, lipids, carbohydrates, thiab nucleic acids. Lawv yog ib qho tseem ceeb hauv kev ua cov ntsiab lus ntawm vesicles coj los ntawm sab nraud ntawm tes.
Kuj Paub, dab tsi hloov lub zog ntawm lub hnub ci mus rau hauv tshuaj lom neeg lub zog uas khaws cia hauv cov zaub mov?
Photosynthesis yog cov txheej txheem los ntawm cov kab mob uas muaj cov xim chlorophyll hloov lub teeb lub zog rau hauv cov khoom siv hluav taws xob uas tuaj yeem khaws cia rau hauv cov ntawv cog lus ntawm cov organic molecules (piv txwv li, suab thaj). Photosynthesis powers yuav luag tag nrho cov trophic chains thiab zaub mov webs ntawm lub ntiaj teb.
Cov qauv ntawv sau npe twg hloov lub zog hauv cov zaub mov mus rau hauv lub zog siv rau hauv cov txheej txheem ntawm tes?
Chloroplast ua haujlwm hloov teeb zog ntawm lub hnub rau hauv qab zib uas tuaj yeem ua tau siv los ntawm cov hlwb.

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
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
Cov txheej txheem dab tsi uas tus kws tshawb fawb siv los tsim ntau cov ntawv luam ntawm DNA xav tau sau rau hauv daim ntawv dawb paug 1?
Molecular Cloning. Cloning tso cai rau tsim ntau cov ntawv luam ntawm cov noob, qhia cov noob, thiab kawm txog cov noob tshwj xeeb. Yuav kom tau txais cov DNA tawg rau hauv cov kab mob hauv cov kab mob hauv daim ntawv uas yuav tau theej lossis nthuav tawm, cov khoom tawg yog thawj zaug tso rau hauv plasmid
Dab tsi yog hom kev sib txuas uas muaj zog tshaj plaws hauv cov zaub mov?
covalent Yog li ntawd, hom kev sib cog lus dab tsi yog feem ntau hauv cov zaub mov? Chemical bonds nyob rau hauv cov zaub mov muaj plaub hom: covalent , ionic, metallic, los yog Van der Waals, nrog covalent thiab ionic daim ntawv cog lus feem ntau.
Dab tsi organelle hloov cov tshuaj zog uas khaws cia hauv cov zaub mov rau hauv lub zog siv tau?
Mitochondria yog cov organelles ua haujlwm uas ua rau lub cell muaj zog. Hauv cov nroj tsuag ntawm tes, chloroplast ua rau cov suab thaj thaum lub sij hawm cov txheej txheem ntawm photosynthesis hloov lub teeb lub zog mus rau hauv tshuaj lub zog khaws cia hauv qabzib
