Lub meridian uas khiav los ntawm Greenwich, England, tau txais thoob ntiaj teb raws li kab ntawm 0 qib longitude , los yog prime meridian. Lub antimeridian yog ib nrab ntawm lub ntiaj teb no, ntawm 180 degrees.
Kuj nug, dab tsi nyob ntawm 0 degrees longitude?
Cov 0 degree kab ntawm longitude uas dhau los ntawm Royal Observatory hauv Greenwich, England yog Greenwich Meridian. Nws tseem hu ua Prime Meridian. Cov kab no yog qhov pib-point rau cov kab ntev uas khiav qaum teb-sab qab teb thiab sib sau ua ke ntawm cov ncej.
Tsis tas li ntawd, qhov tseem ceeb meridian yog dab tsi thiab nws nyob qhov twg? Cov Prime Meridian , raws li nws hla Greenwich, England, suav hais tias yog 0 degrees longitude. Vim tias ob qho tib si equator thiab cov Prime Meridian yog cov kab kev xav, lawv ob leeg tau tsim los ntawm noob neej ntawm qee qhov chaw hauv tib neeg keeb kwm.
Ib tug kuj nug, vim li cas Greenwich 0 degrees longitude?
Qhov tseem ceeb meridian yog kab ntawm 0 longitude , qhov pib taw tes rau kev ntsuas qhov deb ntawm sab hnub tuaj thiab sab hnub poob ib ncig ntawm lub ntiaj teb. Tus thawj meridian yog arbitrary, txhais tau tias nws tuaj yeem xaiv tau nyob qhov twg. Lawv xaiv lub meridian dhau los ntawm Royal Observatory hauv Greenwich , Askiv.
Qhov piv txwv ntawm longitude yog dab tsi?
Ntev yog qhov kev ncua deb ntawm qhov chaw sab hnub tuaj lossis sab hnub poob ntawm meridian ntawm Greenwich, England. Rau piv txwv , New York thiab Miami muaj yuav luag ib yam nkaus longitudes : nyob ib ncig ntawm 80 degrees sab hnub poob. Berlin ntawm qhov tod tes muaj ib longitude ntawm 13 degrees sab hnub tuaj. Beijing, Suav teb, muaj ib longitude ntawm 116 degrees sab hnub tuaj.

Dab tsi yog qhov txawv ntawm lub teeb pom kev thiab pom tsis pom?
Tsis muaj qhov sib txawv ntawm lub teeb pom kev thiab pom tsis pom lub teeb xws li xov tooj cua nthwv dej thiab X rays. Lawv yog tag nrho cov electromagnetic tsis txawv nyob rau hauv ib txoj kev xwb: lawv wavelength. Lub teeb ultraviolet, X rays, thiab gamma rays tag nrho muaj luv luv wavelengths tshaj li pom lub teeb
Puas yog ib qho arbitrarily xaiv kab ntawm longitude uas ua raws li 0 °?
Tus thawj meridian yog kab ntawm 0 longitude, qhov pib taw tes rau kev ntsuas qhov deb ntawm sab hnub tuaj thiab sab hnub poob ib ncig ntawm lub ntiaj teb. Tus thawj meridian yog arbitrary, txhais tau tias nws tuaj yeem xaiv tau nyob qhov twg. Ib kab ntawm longitude (ib qho meridian) tuaj yeem ua haujlwm raws li 0 longitude kab
Lub npe ntawm cov enzyme uas kuaj pom hauv qhov kev kuaj pom zoo catalase yog dab tsi?
Catalase Test- Ntsiab Cai, Siv, Txheej Txheem, Txhais Lus Txhais nrog ceev faj. Qhov kev sim no qhia pom tias muaj catalase, ib qho enzyme uas ua rau cov pa tawm ntawm cov pa oxygen los ntawm hydrogen peroxide (H2O2)
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
