Hauv physics , lub sij hawm teeb Qee zaum hais txog hluav taws xob hluav taws xob hluav taws xob ntawm ib qho wavelength, txawm pom los tsis pom. Hauv qhov kev nkag siab no, gamma rays, X-rays, microwaves thiab xov tooj cua tsis yog teeb . Qhov no dual yoj-zoo li thiab particle-zoo li xwm ntawm teeb yog hu ua yoj-particle dual.
Tom qab ntawd, light science yog dab tsi?
Cov Kev tshawb fawb ntawm Vision thiab Teeb Txhawm rau muab nws yooj yim, teeb yog ib hom radiant zog uas peb muaj peev xwm pom pom nrog peb ob lub qhov muag. Pom tau teeb yog ib feem me me ntawm ib feem loj ntawm qhov hu ua Electromagnetic Spectrum, uas muaj tag nrho cov zog hom uas taug kev los ntawm qhov chaw hauv ib lub manor zoo li nthwv dej.
Tom qab ntawd, lo lus nug yog, lub teeb yog dab tsi? Wave-Particle Duality ntawm Teeb . Quantum txoj kev xav qhia peb tias ob qho tib si teeb thiab cov teeb meem muaj cov me me uas muaj wavelike zog txuam nrog lawv. Teeb yog muaj li ntawm cov khoom hu ua photons, thiab teeb meem yog muaj li ntawm cov khoom hu ua electrons, protons, neutrons.
Tsis tas li ntawd, lub teeb yog dab tsi?
Teeb yog ib feem ntawm cov electromagnetic spectrum, uas muaj xws li xov tooj cua tsis mus rau gamma rays. Cov hluav taws xob hluav taws xob hluav taws xob, raws li lawv cov npe qhia yog qhov hloov pauv ntawm hluav taws xob thiab sib nqus teb, uas tuaj yeem thauj lub zog ntawm ib qho mus rau lwm qhov.
Dab tsi yog 5 yam khoom ntawm lub teeb?
Qhov tseem ceeb khoom ntawm pom teeb yog kev siv zog, kev nthuav tawm kev taw qhia, zaus lossis wavelength spectrum, thiab polarization, thaum nws ceev hauv lub tshuab nqus tsev, 299, 792, 458 meters ib ob, yog ib qho tseem ceeb ntawm qhov xwm txheej.

Dab tsi yog acid nyob rau hauv lub cev science?
Cov kua qaub yog ib hom tshuaj uas pub cov protons lossis hydrogen ions thiab / lossis txais cov khoom siv hluav taws xob. Feem ntau cov kua qaub muaj cov hydrogen atom sib koom ua ke uas tuaj yeem tso tawm (dissociate) los ua ib qho cation thiab anion hauv dej
Dab tsi yog qhov tseeb ntawm lub cev lub cev lub cev kev xav xav?
Lub cev lub cev lub ntsiab lus kev xav (PSSH) yog ib txoj hauj lwm hauv lub tswv yim ntawm kev txawj ntse tsim los ntawm Allen Newell thiab Herbert A. 'Ib lub cim lub cev muaj qhov tsim nyog thiab txaus txhais tau tias rau kev ua haujlwm ntse.'
Dab tsi yog qhov teeb meem ntawm lub teeb nyob rau hauv lub ntuj hmo ntuj hu ua?
Gegenschein, tseem hu ua Counterglow, oval thaj ntawm faint luminosity raws nraim rau lub hnub nyob rau hauv lub hmo ntuj. Lub thaj ntawm lub teeb yog li faint nws tuaj yeem pom tsuas yog thaum tsis muaj lub hli, nyob deb ntawm lub nroog teeb, thiab nrog lub qhov muag yoog rau qhov tsaus ntuj
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
