Muaj tsib pawg loj ntawm cov tebchaw uas ua rau tib neeg lub cev. Lawv yog cov carbohydrates, lipids , proteins, nucleotides, thiab dej.
Ua raws li qhov no, dab tsi yog 5 lub ntsiab organic tebchaw?
Muaj plaub yam tseem ceeb, lossis chav kawm, ntawm cov organic tebchaw pom nyob rau hauv txhua yam muaj sia: carbohydrates , lipids , cov proteins , thiab nucleic acids . Tsis tas li ntawd, muaj lwm cov organic tebchaw uas yuav pom nyob rau hauv los yog tsim los ntawm ib co kab mob.
Ib tug kuj yuav nug, dab tsi yog 4 loj organic tebchaw thiab lawv cov dej num? Txhua yam kab mob xav tau plaub hom organic molecules: nucleic acids, proteins, carbohydrates thiab lipids; lub neej tsis tuaj yeem nyob yog tias ib qho ntawm cov molecules no ploj lawm.
- Nucleic Acids. Cov nucleic acids yog DNA thiab RNA, los yog deoxyribonucleic acid thiab ribonucleic acid, feem.
- Cov protein.
- Carbohydrates.
- Lipids.
Tsis tas li ntawd, 4 hom kev sib txuas yog dab tsi?

Dab tsi yog 10 lub ntsiab lus tseem ceeb ntawm biology?
Cov kev sib txuas no ua rau 10 lub ntsiab lus ntawm biology. Cov khoom muaj xwm ceev. Lub neej muaj nyob rau hauv daim ntawv hierarchical, los ntawm ib leeg-celled kab mob mus rau tag nrho biosphere, nrog rau tag nrho nws cov ecosystems. Lub Cell. Cov ntaub ntawv keeb kwm yav dhau los. Structure thiab Function. Environmental Interactions. Tawm tswv yim thiab kev cai. Unity thiab Diversity. Evolution
Dab tsi yog lub ntsiab lus tseem ceeb tshaj plaws hauv Pawg 7a?
Feem ntau cov halogens yog electron tshaib plab, zoo li fluorine.Halogens tuaj yeem raug xa mus rau pawg 7A, pawg 17, lossis pawg VIIA cov ntsiab lus
Dab tsi yog ob lub ntsiab lus tseem ceeb rau kev sib npaug?
Cov Ntsiab Lus Tseem Ceeb Muaj ob yam xwm txheej uas yuav tsum tau ua kom tau raws li qhov khoom kom muaj kev sib npaug. Thawj qhov xwm txheej yog tias lub zog ntawm cov khoom yuav tsum yog xoom rau qhov khoom sib npaug. Yog hais tias lub zog net yog xoom, ces net force raws li ib qho kev taw qhia yog xoom
