Over time, the scientific and technological advances have allowed a lot of information about the cellular metabolism and this revealed that the reactions that occur within cells are very complex, even a single bacterium. With the progress of astronomy and geology, the use of the spectroscope, it was possible to study further the chemical composition of stars provoking discussions in the scientific community regarding the age of the Earth and Solar System. Apparently, the riddle of the question to know the origin of life can be in the actual conditions of the early Earth (ZAIA, Spectroscope instrument used to analyze the decomposition of light in Chemistry, Physics and Astronomy. Representation of Spectroscope created by Robert Wilhelm Eberhard BUNSEN (1811-1899) and Gustav Robert KIRCHHOFF (1824-1887), instructors, Chemistry and Physics at the University of Heidelberg, Germany. Image source: Museum of the Faculty of Medicine, University of Valenia, Spain. In 1860, Bunsen and Kirchhoff demonstrated to a group of geologists to identify elements such as iron, copper, lead, sodium and potassium ores, by staining the flame on a burner specially designated and currently called Bunsen burner. The solid sample was dissolved in water and the resulting solution was introduced into a flame. Can estimate the concentrations of the ele- tion by comparing the color intensity of solutions of known concentrations with the intensity of the sample solutions of solid minerals.

Química Nova, Sep / Oct 2004, vol.27, no.5, p.832-836. Living beings are constituted mainly by the chemical elements hydrogen (H), carbon (C), nitrogen (N) and oxygen (O). And these, according to the Russian biochemist Alexander Ivanovich Oparin, were present in the molecules of the gases of the early atmosphere. Life would have arisen by the reactions between gases methane (CH ammonia (NH hydrogen (H and water vapor (H O), as explained Oparin, in 1922, and was later evidenced by the experience of North American scientists Stanley L. Miller and Harold C. Urey of the University of Chicago in 1953? Does anyone managed to make a living in the laboratory from inert matter? DEBATE The combination of methane, ammonia, hydrogen and water vapor could produce anything, everything, or just what was possible?

Tijekom vremena, znanstveni i tehnološki napredak omogućio puno informacija o stanični metabolizam, a to otkriva da su reakcije koje se odvijaju u stanicama su vrlo složeni, ni jedna bakterija. S napretkom astronomije i geologije, korištenje spektroskop, bilo je moguće daljnje istraživanje kemijskog sastava zvijezde, izazivajući rasprave u znanstvenoj zajednici u odnosu na dob Zemlje i Sunčevog sustava. Navodno, zagonetka pitanje kako zna podrijetlo života može biti u stvarnim uvjetima u ranoj Zemlji (ZAIA, Spektroskop instrument za analizu razlaganje svjetlosti u kemiju, fiziku i astronomiju. Zastupljenost spektroskop stvorio Robert Wilhelm Bunsen Eberhard (1811-1899) i Gustav Kirchhoff Robert (1824-1887), instruktora, kemiju i fiziku na Sveučilištu u Heidelbergu u Njemačkoj. Slika izvor: Muzej Medicinskom fakultetu Sveučilišta u Valenia, Španjolska. Godine 1860, Bunsen i Kirchhoff pokazao na skupinu geologa identificirati elemente kao što su željezo, bakar, olovo, natrija i kalija ruda, pri bojanju plamen na plameniku, a posebno predviđenom trenutno zove Bunsenov plamenik. Kruti uzorak je otopljen u vodi i rezultiralo rješenje je uveden u plamenu. Može procijeniti koncentracije ele- tion usporedbom intenziteta boje otopine poznate koncentracije s intenzitetom uzorka rješenja krutih minerala.

Quimica Nova, rujan / listopad 2004, vol.27, br.5, p.832-836. Živa bića sastoje se uglavnom od vodika kemijskih elemenata (H), ugljik (C), dušik (N) i kisika (O). A to, prema ruskom biokemičar Alexander Ivanoviča Oparin, bili su prisutni u molekule plinova u ranoj atmosferi. Život bi nastala po reakcijama između plinova metana (CH amonijaka (NH vodik (H i vodene pare (H O), kao što je objašnjeno Oparin, u 1922, a kasnije svjedoče iskustva Sjevernoj američki znanstvenici Stanley L. Miller i Harold C. Urey na Sveučilištu u Chicagu u 1953? Da li itko uspio napraviti žive u laboratoriju s inertnim pitanju? DEBATA Kombinacija metana, amonijaka, vodika i vodenu paru mogao proizvesti ništa, sve, ili samo ono što je bilo moguće? Razmnožavanje je posljedica života ili života je posljedica razmnožavanja?
