Vim li cas puas lub hnub qub loj loj hloov pauv txawv dua ib tsawg hnub qub ? A) Nws tuaj yeem hlawv roj ntau dua vim nws cov tub ntxhais tuaj yeem kub dua. Nws muaj ib qis lub ntiajteb txawj nqus yog li nws tsis tuaj yeem rub ntau roj los ntawm qhov chaw.
Ib yam li ntawd, koj yuav nug, qhov txawv ntawm lub hnub qub qis thiab lub hnub qub loj yog dab tsi?
Ob leeg, a Lub hnub qub qis thiab lub hnub qub loj heev Yuav pib nrog fuseing hydrogen rau hauv Helium, tab sis a siab loj Star yuav kub hnyiab tau sai dua vim muaj zog thiab kub hauv tub ntxhais. Ib ob txawv yog lub peev xwm los tsim cov ntsiab lus hnyav. Qhov no hu ua Neutron Lub hnub qub thiab muaj qhov loj ntawm rougly 20km.
Tsis tas li ntawd, dab tsi yog qhov evolution ntawm lub hnub qub qis? Cov theem tseeb ntawm evolutions yog: Subgiant ceg (SGB) - hydrogen plhaub hlawv - txheej txheej o. Liab Giant ceg - helium tshauv core compresses - nce hydrogen plhaub hlawv. Thawj Dredge Up - nthuav dav cua txias hnub qub - ua kom cov pa roj carbon, nitrogen thiab oxygen nce siab - hnub qub ua kom sov.
Tom qab ntawd, vim li cas cov hnub qub siab thiab qis qis hloov pauv txawv?
Qhov sib txawv ntawm qhov kub ntawm cov cores ntawm lub siab - pawg hnub qub thiab qis - pawg hnub qub hlawv helium ua rau lawv evolve txawv thaum lawv dhau los ua neeg loj.
Vim li cas cov hnub qub loj tuaj yeem hlawv helium yooj yim dua li cov hnub qub qis?
A) A siab - pawg hnub qub tub ntxhais yog twb kub heev, yog li nws tsuas xav tau compress nws cov tub ntxhais me ntsis rau hlawv helium . C) Tsawg - hnub qub loj muaj proportionately tsawg helium tshaj siab - hnub qub loj.

Yam khoom twg feem ntau txiav txim siab seb lub hnub qub loj lossis lub hnub qub supergiant yuav tsim?
Pawg (1) feem ntau txiav txim siab seb lub hnub qub loj lossis lub hnub qub supergiant yuav tsim. Cov hnub qub tsim nyob rau hauv cov cheeb tsam ntawm qhov ntom ntom hauv thaj tsam interstellar. Cov cheeb tsam no yog hu ua molecular huab thiab muaj feem ntau ntawm hydrogen. Helium, nrog rau lwm cov ntsiab lus, kuj pom nyob rau hauv cheeb tsam no
Vim li cas cov hnub qub dhau los ntawm kev hloov pauv hloov pauv?
Stellar evolution yog tus txheej txheem uas lub hnub qub hloov pauv nyob rau lub sijhawm. Cov hnub qub uas muaj tsawg kawg yog ib nrab ntawm lub hnub tuaj yeem pib tsim lub zog los ntawm kev sib xyaw ntawm helium ntawm lawv cov tub ntxhais, thaum lub hnub qub ntau dua tuaj yeem sib xyaw cov ntsiab lus hnyav dua raws li cov khoom sib xyaw ua ke
Vim li cas tom qab kev hloov pauv kev hloov pauv tseem ceeb?
Kev hloov pauv tom qab kev txhais lus (PTMs) xws li glycosylation thiab phosphorylation ua lub luag haujlwm tseem ceeb ntawm kev ua haujlwm ntawm hemostatic proteins thiab tseem ceeb heev hauv kev teeb tsa kab mob. Xws li theem nrab hloov pauv rau cov proteins hemostatic muaj ntau yam cuam tshuam rau lawv lub peev xwm los cuam tshuam nrog lwm cov proteins
Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Cov kev hloov ntawm lub cev txawv ntawm cov tshuaj hloov pauv li cas muab ib qho piv txwv ntawm txhua tus?
Kev hloov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub cev hloov pauv yog thaum cov teeb meem hloov pauv tab sis tsis yog tshuaj lom neeg. Piv txwv ntawm kev hloov tshuaj lom neeg yog hlawv, ua noj, xeb, thiab rotting. Piv txwv ntawm kev hloov lub cev yog boiling, melting, khov, thiab shredding
