Cov kab mob muaj sia ua tau los ntawm carbon, muaj sia nyob Kuj tseem muaj ntau ntawm hydrogen, oxygen, nitrogen, sulfur, thiab phosphorous. Cov atoms ua ke ua ke los tsim cov molecules complex ntawm ntau hom: proteins, carbohydrates, lipids, thiab nucleic acids. Thiab cov no yog nyob rau hauv lem lub tsev blocks rau cell.
Ib yam li ntawd, nws yog nug, dab tsi yog cov khoom muaj sia feem ntau ua los ntawm?
Koj lub cev yog ua feem ntau ntawm peb yam: carbon, oxygen, thiab hydrogen. Nco ntsoov, lub ntsiab lus yog qhov yooj yim tshaj plaws ntawm cov teeb meem. Koj lub cev kuj muaj cov sulfur, nitrogen, phosphorus, thiab txog kaum ob lwm yam khoom. Txhua yam muaj sia yog ua los ntawm cov khoom xyaw no.
Kuj Paub, puas yog txhua yam muaj sia ua los ntawm carbon? Txhua yam muaj sia yog ua ntawm cov organic molecules, uas nyob rau hauv lem yog ua qhov tseem ceeb ntawm carbon , hydrogen, nitrogen, oxygen, phosphorus thiab sulfur. Tag nrho nyob yam yog ua ntawm cov ntsiab lus no, tab sis tsis yog txhua yam ua ntawm cov ntsiab lus no muaj dab tsi ua rau lub neej.
Ib yam li ntawd ib tug yuav nug, dab tsi muaj sia nyob yog tsim los ntawm cov hlwb?
Cells yog lub tsev blocks ntawm lub ntiaj teb no nyob. Cov khoom muaj sia muaj ntau hom kab mob, archaea ua algae, fungi, protozoans, tsiaj txhu , thiab cov nroj tsuag tag nrho muaj ib los yog ntau lub hlwb. Cells yog tsim los ntawm cov khoom uas pab cov khoom muaj sia noj, ua pa, tso cov khoom pov tseg, thiab ua txhua yam tsim nyog ntawm lub neej.
Cov tsiaj nyob hu ua dab tsi?
Lub cev yog ib tus neeg yam muaj sia . Nws yog ib qho yooj yim kom paub txog a yam muaj sia , tab sis tsis yooj yim los txhais nws. Tsiaj txhu thiab nroj tsuag yog kab mob , pom tseeb. Kab mob yog biotic, los yog nyob , ib feem ntawm ib puag ncig.

Dab tsi yog cov kws tshawb fawb taxa siv los faib cov khoom muaj sia?
Kev tshawb fawb ntawm kev faib cov tsiaj muaj sia hu ua taxonomy. Linnaeus tau qhia txog cov txheej txheem kev faib tawm uas tsim los ntawm kev faib tawm niaj hnub no. Taxa hauv Linnaean system suav nrog lub nceeg vaj, phylum, chav kawm, kev txiav txim, tsev neeg, genus, thiab hom
Cov qauv ntawm cov pa roj carbon zoo li cas rau ntau yam ntawm macromolecules pom hauv cov khoom muaj sia?
Cov pa roj carbon atom muaj cov khoom tshwj xeeb uas tso cai rau nws los tsim cov ntawv cog lus rau ntau li plaub lub atoms sib txawv, ua kom muaj ntau yam khoom zoo tagnrho los ua tus qauv tsim qauv, lossis "ncaj qaum," ntawm macromolecules
Dab tsi yog cov yam ntxwv ntawm cov khoom muaj sia?
Ib yam uas tsis muaj sia yog ib qho uas tsis muaj lossis tau tso tseg tsis pom cov yam ntxwv ntawm lub neej. Yog li, lawv tsis muaj lossis tsis pom qhov muaj peev xwm rau kev loj hlob, kev loj hlob, kev ua pa, metabolism, thiab kev txav mus los. Lawv kuj tsis muaj peev xwm teb rau stimuli los yog evolve thiab hloov mus rau lawv ib puag ncig
Dab tsi yog qhov zoo ntawm cov khoom muaj sia?
Cov no yog xya yam ntxwv ntawm cov tsiaj muaj sia. 1 Khoom noj khoom haus. Cov khoom muaj sia nyob hauv cov khoom siv los ntawm lawv ib puag ncig uas lawv siv rau kev loj hlob lossis muab lub zog. 2 Ua pa. 3 Kev txav mus los. 4 Kev tso tawm. 5 Kev loj hlob. 6 Kev tsim tawm. 7 Kev xav
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
