Txoj kev xav tuaj yeem tsis lees paub vim tsis muaj cov ntaub ntawv sim uas txhawb nqa nws, thiab muaj cov ntaub ntawv sim uas qhia pom cov amino acids tuaj yeem tshwm sim los ntawm "cov kua zaub ua ntej" uas peb xav tau Lub ntiaj teb thaum ntxov kom muaj - nws hu ua Miller-Urey kev sim.
Leej twg disproved vitalism theory?
Txoj kev xav tau lees paub los ntawm Friedrich Wohler, uas tau pom tias cov cua sov nyiaj cyanate (ib qho tshuaj inorganic) nrog ammonium chloride (lwm inorganic compound) tsim urea, tsis muaj kev pab los ntawm ib tug inorganic compound. Cov kab mob nyob los yog ib feem ntawm cov kab mob muaj sia.
Txoj kev xav ntawm qhov tseem ceeb tau dag li cas?
Kev dag ntawm txoj kev xav: cov khoom siv dag zog ntawm urea tau pab ua kom muaj txiaj ntsig tseem ceeb Urea tau tshawb pom hauv cov zis hauv xyoo 1720 thiab tau suav tias yog cov khoom ntawm lub raum. Lub sijhawm ntawd nws tau ntseeg dav tias cov organic tebchaw hauv cov nroj tsuag thiab tsiaj txhu tsuas yog ua tau nrog kev pab los ntawm "txoj cai tseem ceeb ".
Leej twg disproved vital force theory thiab ua li cas?
Vital Force Theory tau raug tsis lees paub hauv xyoo 1823 thaum Friedrich Wöhler ua ke thawj cov organic compound urea los ntawm ib qho inorganic compound, Ammonium cyanate.
Leej twg tsis lees paub qhov kev xav ntawm lub zog tseem ceeb thiab vim li cas?
Vital Force Theory tau raug tsis lees paub hauv xyoo 1823 thaum Friedrich Wöhler ua ke ua ntej cov organic compound urea los ntawm ib qho inorganic compound Ammonium cyanate. Woehler pom tias urea, ib qho 'organic' khoom, tuaj yeem ua ke hauv vitro yam tsis muaj 'lub zog tseem ceeb' lossis muaj sia nyob.

Vim li cas kev ceeb toom kev tso cai tseem ceeb hauv kev tshawb fawb?
Qhia kev pom zoo yog ib feem tseem ceeb ntawm rau npe rau hauv kev sim tshuaj vim nws muab cov ntaub ntawv muaj peev xwm rau cov neeg koom nrog txhua yam lawv xav tau kom nkag siab txog yam lawv tuaj yeem pab dawb Tsis muaj kev pom zoo rau cov ncauj lus tej zaum yuav tsis nkag siab qhov lawv koom nrog .
Tus kws tshawb fawb twg tsis lees paub lub tswv yim ntawm kev tsim lub neej?
Los ntawm 1860, kev sib cav tau dhau los ua kom sov siab uas Paris Academy of Sciences muab khoom plig rau txhua qhov kev sim uas yuav pab daws qhov teeb meem no. Qhov khoom plig tau thov rau xyoo 1864 los ntawm Louis Pasteur, raws li nws tau tshaj tawm cov txiaj ntsig ntawm kev sim nws tau ua kom tsis lees paub cov neeg tsim tawm hauv cov kab mob microscopic .
Thaum tsim cov lus nug tshawb fawb tus kws tshawb fawb yuav tsum?
Teb: Thaum tsim cov lus nug tshawb fawb, tus kws tshawb fawb yuav tsum sau ib lo lus nug uas muaj cov lus teb tsis tau txiav txim siab. Kev piav qhia: Hauv lwm lo lus, yuav tsum muaj laj thawj los ua koj qhov kev tshawb fawb . Cov lus nug tshawb fawb yog dab tsi?
Vim li cas kev coj ua ntawm kev coj ncaj ncees tseem ceeb hauv kev tshawb fawb?
Muaj ntau yam laj thawj vim li cas nws tseem ceeb kom ua raws li kev coj ncaj ncees hauv kev tshawb fawb. Ua ntej, qauv txhawb nqa lub hom phiaj ntawm kev tshawb fawb, xws li kev paub, qhov tseeb, thiab zam kev ua yuam kev. Piv txwv li, kev txwv tsis pub tshaj tawm, kev dag, lossis qhia tsis tseeb cov ntaub ntawv tshawb fawb txhawb qhov tseeb thiab txo qhov yuam kev .
Vim li cas nws tseem ceeb rau kev sib piv cov ntaub ntawv hauv kev tshawb fawb zoo?
Triangulation pab kom siv tau cov ntaub ntawv los ntawm kev txheeb xyuas hla dhau los ntawm ntau tshaj ob qhov chawNws ntsuas qhov sib xws ntawm kev tshawb pom tau los ntawm cov cuab yeej sib txawv thiab ua rau muaj kev tswj hwm, lossis tsawg kawg ntsuas, qee qhov kev hem thawj lossis ntau yam ua rau cuam tshuam rau peb cov txiaj ntsig .
