Raws li koj tuaj yeem pom hauv daim duab ncuav qab zib ntawm sab laug, kwv yees li 97 feem pua ntawm koj lub cev qhov hnyav tsuas yog plaub lub ntsiab lus tseem ceeb- oxygen , carbon , hydrogen , thiab nitrogen . Rau qhov feem ntau ntawm cov khoom muaj sia nyob yog carbon , hydrogen , oxygen , nitrogen , phosphorus , thiab sulfur.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog plaub lub ntsiab lus feem ntau pom nyob rau hauv cov kab mob muaj sia quizlet?
carbon , hydrogen , oxygen , nitrogen , phosphorus, thiab sulfur. Dab tsi yog cov ntsiab lus ntau tshaj plaws uas muaj cov khoom muaj sia?
Ib tug kuj yuav nug, dab tsi yog plaub lub ntsiab lus tshaj plaws hauv biomolecules? Txawm hais tias muaj ntau tshaj 25 hom ntsiab lus tuaj yeem pom hauv biomolecules, rau lub ntsiab lus feem ntau yog. Cov no yog hu ua CHNOPS cov ntsiab lus; cov ntawv sawv cev rau cov tshuaj abbreviations ntawm carbon , hydrogen , nitrogen , oxygen , phosphorus, thiab sulfur.
Hais txog qhov no, dab tsi yog 4 yam tseem ceeb ntawm cov khoom muaj sia?
Qee qhov ntau tshaj plaws hauv cov kab mob muaj sia muaj xws li carbon, hydrogen, nitrogen , oxygen , sulfur, thiab phosphorus. Cov no tsim cov nucleic acids, proteins, carbohydrates, thiab lipids uas yog cov khoom tseem ceeb ntawm cov khoom muaj sia.
Cov ntsiab lus dab tsi feem ntau pom hauv cov kab mob muaj sia?
Cov kab mob uas muaj sia nyob feem ntau muaj cov kab mob ntawm ntau lub ntsiab lus, tab sis cov uas muaj ntau tshaj plaws yog oxygen, carbon, hydrogen, nitrogen, calcium thiab phosphorus
- Oxygen. Oxygen yog cov khoom siv ntau tshaj plaws uas muaj nyob hauv cov kab mob uas muaj sia nyob, suav txog 65% ntawm tib neeg lub cev.
- Cov pa roj carbon.
- Hydrogen.
- Nitrogen.
- Sulfur.
- Phosphorus.

Dab tsi yog qhov ntau tshaj thiab tseem ceeb tshaj plaws inorganic compound nyob rau hauv lub cev?
Dej yog cov khoom siv tsis muaj tshuaj lom ntau tshaj plaws, ua rau ntau dua 60% ntawm lub ntim ntawm cov hlwb thiab ntau dua 90% ntawm cov kua hauv lub cev zoo li ntshav. Ntau yam tshuaj yaj nyob hauv dej thiab tag nrho cov tshuaj lom neeg uas tshwm sim hauv lub cev ua li ntawd thaum yaj hauv dej
Dab tsi abiotic yam muaj qhov cuam tshuam loj tshaj plaws rau cov kab mob suab puam?
Los nag, dej muaj, tshav ntuj, thiab qhov kub thiab txias yog txhua yam abiotic yam. Cov suab puam yog tus cwj pwm los ntawm lawv qhov tsis muaj dej nag. Txawm hais tias peb feem ntau xav txog cov suab puam kub, qee qhov suab puam tuaj yeem txias heev. Feem ntau cov suab puam tau nyob ib ncig ntawm 10 ntiv tes los nag hauv ib xyoos
Dab tsi yog cov roj tseem ceeb tshaj plaws hauv cov cua?
Cov pa roj ntau tshaj plaws hauv qhov chaw yog nitrogen, nrog oxygen thib ob. Argon, ib qho roj inert, yog qhov thib peb feem ntau cov pa roj hauv cov cua
Dab tsi yog qhov tseem ceeb tshaj plaws rau cov khoom muaj sia?
Dej? Dej yog ib qho inorganic molecule nrog cov khoom tshwj xeeb uas ua rau nws yog ib qho tseem ceeb tshaj plaws rau cov khoom muaj sia. Nyob rau hauv cov dej molecule (H2O), cov hydrogen thiab oxygen atoms daim ntawv cog lus kom cov hluav taws xob nqi yog unevenly faib
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
