Raws li ib txoj kev xav, tshuaj evolution tshwm sim nyob rau hauv plaub theem . Nyob rau hauv thawj theem ntawm tshuaj evolution , molecules nyob rau hauv ib puag ncig thaum ub tsim cov organic yooj yim, xws li amino acids.
Tsuas yog li ntawd, dab tsi yog tshuaj evolution?
tshuaj evolution . Kev tsim ntawm complex organic molecules (saib cov organic molecule) los ntawm yooj yim inorganic molecules los ntawm tshuaj kev tshwm sim nyob rau hauv dej hiav txwv thaum lub sij hawm thaum ntxov keeb kwm ntawm lub ntiaj teb; thawj kauj ruam ntawm txoj kev loj hlob ntawm lub neej nyob rau hauv lub ntiaj teb no.
Tsis tas li ntawd, leej twg tau hais txog kev tshawb fawb tshuaj evolution? Bernal tau sau lo lus biopoiesis hauv xyoo 1949 los hais txog keeb kwm ntawm lub neej. Nyob rau hauv 1967, nws hais tias nws tshwm sim nyob rau hauv peb "theem": keeb kwm ntawm biological monomers.
Ib yam li ntawd, tej zaum koj yuav nug tias, peb theem twg hauv kev tsim lub neej hauv ntiaj teb?
Peb theem ntawm tus keeb kwm ntawm lub neej txheej txheem: bifurcation, stabilization thiab inversion.
Cov kws tshawb fawb ntseeg tias tshuaj evolution tshwm sim qhov twg?
nyob ntawd yog ib tug xov tooj ntawm hypotheses nyob rau hauv thawj lub hauv paus ntawm lub neej. Qhov kev xav tau yog tias thawj cov molecular replicators tuaj rau hauv lub neej nyob ze ntawm cov cua kub hauv dej hiav txwv, hauv qhov tsua tob, lossis hauv cov dej ntiav ze ze ntawm lub roob hluav taws.

Dab tsi yog cov kauj ruam koom nrog hauv electroplating?
Cov hauv qab no piav qhia txog cov kauj ruam ua hauv cov txheej txheem zinc electroplating. Kauj Ruam 1 - Ntxuav lub substrate. Kauj Ruam 2 - Ua kom lub substrate. Kauj Ruam 3 - Kev Npaj Cov Tshuaj Plating. Kauj Ruam 4 - Zinc Electroplating. Kauj Ruam 5 - Yaug thiab ziab
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Cov kauj ruam ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov?
Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase, anaphase thiab telophase. Cov txheej txheem ntawm cell faib tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sij hawm anaphase thiab telophase. Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib
Dab tsi yog tsib kauj ruam koom nrog hauv kev tshaj tawm xov tooj ntawm tes?
Kev sib txuas lus los ntawm extracellular signals feem ntau muaj rau cov kauj ruam: (1) synthesis thiab (2) tso tawm cov signaling molecule los ntawm lub signaling cell; (3) thauj cov teeb liab mus rau lub hom phiaj ntawm tes; (4) nrhiav pom ntawm lub teeb liab los ntawm ib qho tshwj xeeb receptor protein; (5) kev hloov pauv hauv cellular metabolism, kev ua haujlwm, lossis kev loj hlob
Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
