HOM MOLECULES
Muaj xya diatomiceElements: Hydrogen (H2Nitrogen (N2), Oxygen (O2), Fluorine ((F2), chlorine ((Cl2), --Iodine ((I2) thiab Bromine (Br2) Cov xya lub ntsiab lus no muaj zog heev uas lawv tuaj yeem pom muaj feem ntau txuas nrog lwm lub atom ntawm tib hom.
Hauv qhov no, 3 qhov piv txwv ntawm molecules yog dab tsi?
Piv txwv ntawm Molecules:
- Cov pa roj carbon dioxide - CO2
- Dej - H2O.
- Oxygen peb ua pa rau hauv peb lub ntsws - O2
- Qab Zib - C12H22O11
- Glucose - C6H12O6
- Nitrous oxide - "Laughing gas" - N2O.
- Acetic acid - ib feem ntawm vinegar - CH3COOH. Txuas Txuas: Piv txwv. Piv txwv science.
Ib yam li ntawd, piv txwv ntawm molecules yog dab tsi? Piv txwv ntawm Molecules
- H2O (dej)
- N2 (nitrogen)
- O3 (ozone)
- Calcium oxide (CaO)
- C6H12O6 (glucose, ib hom qab zib)
- NaCl (lub rooj ntsev)
Tsis tas li ntawd, muaj pes tsawg hom molecules muaj?
Muaj peb hom molecules uas yog lub ntsiab molecule , lub compound molecule & qhov sib tov.
Dab tsi yog qhov feem ntau molecule?
hydrogen

Vim li cas peb ntsuas qee qhov kev ncua deb hauv astronomy hauv lub teeb xyoo thiab qee qhov hauv astronomical units?
Feem ntau cov khoom nyob rau hauv qhov chaw nyob deb li deb, hais tias siv ib tug kuj me me chav nyob deb, xws li ib tug astronomical unit, yog tsis siv. Hloov chaw, astronomers ntsuas qhov deb ntawm cov khoom uas nyob sab nraum peb lub hnub ci hauv lub teeb xyoo. Qhov ceev ntawm lub teeb yog kwv yees li 186,000 mais lossis 300,000 kilometers ib ob
Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog txheej txheem ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
