Kev txhais ntawm Khoom ( biology )
Cov khoom yog hom tsim los ntawm cov tshuaj tiv thaiv. Thaum lub sij hawm ib tug tshuaj tiv thaiv reagents yog hloov mus rau hauv cov khoom tom qab dhau los ntawm kev hloov pauv lub zog siab. Cov txheej txheem no ua rau kev noj cov tshuaj reagents
Hais txog qhov no, piv txwv ntawm cov khoom hauv biology yog dab tsi?
Hauv biochemistry, enzymes ua cov tshuaj lom neeg los hloov cov substrate rau khoom . Rau piv txwv , cov cov khoom Cov enzyme lactase yog galactose thiab qabzib, uas yog tsim los ntawm substrate lactose.
Tsis tas li ntawd, cov khoom pov tseg yog dab tsi? cov khoom pov tseg . npe. Ib qho khoom siv tsis zoo lossis tsis xav tau lossis cov khoom tsim tawm thaum lub sijhawm lossis los ntawm cov txheej txheem, xws li cov metabolism lossis kev tsim khoom.
Ib yam li ntawd, nws yog nug, dab tsi yog cov khoom hauv kev tshawb fawb?
Hauv chemistry, a khoom yog ib yam khoom uas yog tsim los ntawm cov tshuaj tiv thaiv. Hauv cov tshuaj tiv thaiv, cov khoom pib hu ua reactants cuam tshuam nrog ib leeg.
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv hauv biology?
npe, plural: tshuaj tiv thaiv . Ib txoj hauv kev uas ib lossis ntau yam tshuaj (reactants) hloov pauv mus rau hauv ib lossis ntau yam tshiab (cov khoom). Tshuaj Kev hloov pauv tuaj yeem cuam tshuam nrog kev txav ntawm electrons hauv kev tsim thiab tawg ntawm tshuaj daim ntawv cog lus.

Dab tsi yog cov khoom lag luam hauv kev sib npaug molecular rau kev ua tiav cov tshuaj tiv thaiv ntawm aqueous barium hydroxide thiab nitric acid?
Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O. Barium hydroxide react nrog nitric acid los tsim barium nitrate thiab dej
Dab tsi yog cov khoom lag luam hauv kev ua lej 4?
Qhov tshwm sim ntawm ob lossis ntau tus lej thaum sib npaug ua ke. Ua lej lej rau menyuam yaus
Vim li cas kev lag luam tshuaj suav hais tias yog kev lag luam yooj yim?
Kev lag luam tshuaj siv cov khoom siv raw los tsim cov khoom lag luam qhia cov kua qaub, hauv paus, alkali thiab ntsev. Cov khoom siv feem ntau yog siv rau hauv kev tsim khoom ntawm lwm cov khoom lag luam xws li iav, chiv, roj hmab, tawv, ntawv thiab textiles. Yog li, peb tuaj yeem hais tias kev lag luam tshuaj lom neeg yog kev lag luam yooj yim
Dab tsi yog cov kev lag luam hauv cov tiaj tiaj sab hauv?
Qee txoj haujlwm tseem ceeb yog ua liaj ua teb, hav zoov, mining, thiab kev lag luam roj thiab roj
Vim li cas thiaj muaj kev lag luam thiab kev ua lag luam?
Ua thiab lagging strands coli, DNA polymerase uas tswj feem ntau ntawm cov synthesis yog DNA polymerase III. Cov strand no yog ua tsis tu ncua, vim hais tias DNA polymerase yog txav mus rau tib qho kev taw qhia raws li cov diav rawg replication. Qhov no tsis tu ncua synthesized strand yog hu ua tus thawj strand
