Lawv yog dab tsi ua yam muaj sia . Lawv yog dab tsi ua rau tsis yog- yam muaj sia . Txhua yam uas peb nkag siab tias qhov teeb meem thiab qhov tseeb, yog suav nrog atoms . Atoms tsim lub ntiaj teb thiab yog vim li cas peb YOG, thiab yog vim li cas peb tuaj yeem cuam tshuam nrog txhua yam.
Ua raws li qhov no hauv kev xav, vim li cas atoms tseem ceeb rau cov kab mob muaj sia?
Atoms ntawm cov ntsiab lus no ua ke thiab tsim ntau txhiab ntawm loj molecules. Cov molecules loj no ua rau cov qauv ntawm cell thiab nqa tawm ntau cov txheej txheem tseem ceeb rau lub neej.
Puas yog atoms muaj sia nyob? Ntawm theem pib, koj lub cev-thiab, qhov tseeb, tag nrho ntawm lub neej, nrog rau lub ntiaj teb uas tsis muaj sia nyob-yog tsim los ntawm atoms , feem ntau koom ua cov qauv loj hu ua molecules. Vim li cas peb tsis tuaj yeem hais tag nrho atoms yog yam muaj sia ? 540 Views. Cov atom tsis yog- nyob , txhua yam yog tsim los ntawm atoms.
Tom qab ntawd, vim li cas cov ntsiab lus tseem ceeb?
Tsis muaj cov ntsiab lus , tsis muaj teeb meem. Cov ntsiab lus kuj yog tseem ceeb vim li cas lawv raug tsim. Tom qab Big Bang, qhov ntxov tshaj plaws keeb rau daim ntawv yog qhov lightest thiab simplest keeb : hydrogen. Cov no cov ntsiab lus tau muab pov rau hauv lub ntiaj teb thaum lub sij hawm stellar explosions hu ua novae.
Yuav ua li cas atoms tsim teeb meem?
Atoms yog qhov yooj yim tsev blocks ntawm dog dig teeb meem . Atoms tuaj yeem koom ua ke los tsim cov molecules, uas ua rau feem ntau ntawm cov khoom nyob ib puag ncig koj. Atoms yog tsim los ntawm cov khoom hu ua protons, electrons thiab neutrons.

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
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Vim li cas rhiab heev yog qhov tseem ceeb rau cov khoom muaj sia?
Cov khoom muaj sia nyob muaj kev nkag siab rau lawv ib puag ncig. Kev nkag siab zoo yog qhov tseem ceeb vim tias nws tso cai rau cov khoom muaj sia mus ntes thiab teb rau cov xwm txheej hauv ntiaj teb nyob ib puag ncig lawv
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
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
