Ib ASAR cov ntaub ntawv yog ib qho archive siv los pob qhov chaws rau ib daim ntawv thov siv Hluav taws xob , qhib lub tsev qiv ntawv siv los tsim cov kev pab cuam hla platform. Nws tau txais kev cawmdim nyob rau hauv ib hom ntawv zoo ib yam li. TAR archives qhov twg cov ntaub ntawv muaj nyob rau hauv archive, xws li. CSS cov ntaub ntawv, yog concatenated ua ke tsis siv compression.
Kuj paub yog, Asar yog dab tsi?
Asar yog ib qho yooj yim uas nws kim heev archive hom, nws ua hauj lwm zoo li tar uas concatenates tag nrho cov ntaub ntawv ua ke yam tsis muaj compression, thaum muaj random kev pab txhawb nqa.
Kuj Paub, puas yog electron ruaj ntseg? “… nco ntsoov tias kev nthuav tawm cov ntsiab lus tsis txaus ntseeg los ntawm cov chaw tsis ntseeg siab ua rau muaj qhov hnyav kev ruaj ntseg pheej hmoo tias Hluav taws xob tsis yog npaj los daws. Txawm tias Hluav taws xob muab cov yam ntxwv los pab cov neeg tsim khoom txo qis kev ruaj ntseg txaus ntshai, qhov no yog tag nrho nyob rau hauv txhais tes ntawm daim ntawv thov tsim tawm.
Tsis tas li ntawd, vim li cas electron tsis zoo?
Hluav taws xob - cov kev siv dav siv hauv desktop daim ntawv thov uas ua rau cov kev pab cuam saum toj kawg nkaus xws li Slack, Atom, thiab Visual Studio Code - raug kev txom nyem los ntawm qhov tsis zoo ntawm kev nyab xeeb uas muaj peev xwm tso cai rau cov neeg tsis ncaj ncees los tua. phem code ntawm cov neeg raug tsim txom cov computers. Qhov ntawd txhais tau tias cov ntawv thov tso siab rau Hluav taws xob tej zaum yuav tau hloov kho.
Puas yog electron ceev?
Kev suav qhia tau hais tias tus hluav taws xob yog mus txog 2,200 kilometers ib ob. Qhov ntawd yog tsawg dua 1% ntawm qhov ceev ntawm lub teeb, tab sis nws yog ceev txaus kom tau txais nws ncig lub ntiaj teb hauv tsuas yog 18 vib nas this. Nyeem txog dab tsi tshwm sim thaum tsis muaj dab tsi mus tau sai dua tshaj qhov ceev ntawm lub teeb.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog suav tias yog ib pawg electron?
Ib pawg hluav taws xob tuaj yeem yog ib khub hluav taws xob, ib khub ib leeg, ib leeg tsis muaj hluav taws xob, ob daim ntawv cog lus lossis triple daim ntawv cog lus ntawm qhov nruab nrab atom. Siv VSEPR txoj kev xav, cov khoom siv hluav taws xob sib txuas thiab cov khub ib leeg ntawm qhov nruab nrab atom yuav pab peb kwv yees cov duab ntawm cov molecule
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
