Lub ntsiab lus twg yog pom nyob rau hauv qhov tsuas yog nyob rau hauv tebchaw quizlet?
Halogens yeej ib txwm pom nyob rau hauv cov xwm txheej incompounds vim hais tias halogens yog heev reactivenonmetals
Dab tsi yog cov xim muaj nyob rau hauv daim ntawv qhia kev phom sij rau kev noj qab haus huv hauv NFPA 704?
NFPA 704 pob zeb diamond kos npe siv los tso saib cov ntaub ntawv no muaj plaub ntu xim: xiav, liab, daj, thiab dawb. Txhua ntu yog siv los txheeb xyuas ib pawg sib txawv ntawm qhov muaj peev xwm txaus ntshai. Ntu xiav ntawm NFPA xim code cim qhia txog kev phom sij rau kev noj qab haus huv
Dab tsi yog periodicity nyob rau hauv daim ntawv periodic?
Periodicity txhais. Nyob rau hauv cov ntsiab lus ntawm chemistry thiab lub sij hawm lub sij hawm, periodicity yog hais txog cov tiam sis los yog rov muaj variations nyob rau hauv lub ntsiab yam ntxwv nrog nce atomic tooj. Periodicity yog tshwm sim los ntawm kev hloov pauv tsis tu ncua thiab kwv yees tau hauv cov qauv atomic
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
Nyob rau hauv dab tsi organelle yog pyruvate oxidation nqa tawm nyob rau hauv ib lub cell?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis nyob rau hauv lub cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv lub mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
