Cov ncej yog tsim ntawm txias molecular hydrogen thiab hmoov av uas raug eroded los ntawm photoevaporation los ntawm ultraviolet lub teeb ntawm kuj ze thiab kub hnub qub. Sab laug ncej yog txog plaub lub teeb xyoo ntev.
Ntawm no, Pillars of Creation puas ploj mus?
Nyob ib ncig ntawm 6,000 xyoo dhau los, lub suab nrov ntawm lub supernova nyob ze yuav poob rau hauv lawv, sib tsoo lawv thiab ntxuav lawv tawm hauv kev hais kwv txhiaj nrog cov hnub qub. Tab sis peb yuav tsis tau saib lawv dim thiab ploj lawm mus txog rau xyoo 3015 (muab lossis nqa). Koj pom, lub Cov ncej nyob 7,000 lub teeb xyoo deb ntawm lub ntiaj teb.
Tsis tas li ntawd, thaum twg cov ncej ntawm kev tsim tau pom? Thaum pib, iconic, 1995 Hubble duab ntawm lub Pillars of Creation yog thawj zaug luam tawm, nws sawv cev rau thawj zaug uas cov evaporating globules, replete nrog cov hnub qub tshiab hauv, yog duab nyob rau hauv xws li nthuav dav.
Thib ob, Pillars of Creation nyob deb npaum li cas?
4 mus rau 5 light-years
Dab tsi yog Eagle Nebula ua los ntawm?
Tam sim no, astronomers paub tias Eagle Nebula yog 5.5 lab-xyoo huab cua ntawm molecular hydrogen gas thiab plua plav stretching kwv yees li 70 lub teeb xyoo los ntawm 55 lub teeb xyoo.

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

Hauv Creationism, kev tsim tshwj xeeb yog cov lus qhuab qhia uas hais tias lub qab ntuj khwb thiab tag nrho lub neej nyob rau hauv itoriginated nyob rau hauv nws tam sim no daim ntawv los ntawm unconditional fiat los yog divinedecree
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 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
