Record number: 1, Textual support number: 1 CONT
Photosynthesis is the chemical process where plants and some bacteria can capture and organically fix the energy of the sun. ... The main product of photosynthesis is a carbohydrate, such as the sugar glucose, and oxygen which is released to the atmosphere. All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight. This chemical reaction is catalyzed by chlorophyll acting in concert with other pigment, lipid, sugars, protein, and nucleic acid molecules. Sugars created in photosynthesis can be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates such as cellulose, or it can be combined with other nutrients such as nitrogen, phosphorus, and sulfur, to build complex molecules such as proteins and nucleic acids. 3, record 1, English, - photosynthesis

Toute la matière vivante découle plus ou moins directement de ce phénomène que l'on appelle aussi «assimilation chlorophyllienne». La photosynthèse est un phénomène très complexe qui donne lieu à divers types de réactions chimiques. Les unes sont dites claires, car elles dépendent directement de la lumière et assurent les transformations proprement photochimiques; les autres, dites obscures, précèdent ou prolongent ces transformations photochimiques vers des synthèses organiques, ou la reconstitution de molécules organiques servant aux transferts d’énergie. 4, record 1, French, - photosynth%C3%A8se

Carbon-14 Method. Radiocarbon dating techniques, first developed by the American chemist Willard F. Libby and his associates at the University of Chicago in 1947, are frequently useful in unravelling time-related problems in archaeology, anthropology, oceanography, pedology, climatology, and recent geology. Through metabolic activity, the level of carbon-14 in a living organism remains in constant balance with the level in the atmosphere or some other portion of the earth's dynamic reservoir, such as the ocean. Upon the organism's death, carbon-14 begins to disintegrate at a known rate, and no further replacement of carbon from atmospheric carbon dioxide can take place. The rapid disintegration of carbon-14 generally limits the dating period to approximately 50,000 years, although the method is sometimes extended to 70,000 years. Uncertainty in measurement increases with the age of the sample. Carbon dating works well on organic specimens such as wood, bone and cloth that are between 2 000 and 20 000 years old. 2, record 5, English, - carbon%2D14%20method

Méthode du carbone 14 : Mise au point par l'Américain Willard Frank Libby en 1949. Le carbone des végétaux provient uniquement du gaz carbonique de l'atmosphère absorbé grâce à l'assimilation chlorophyllienne. Sous l'effet des rayons cosmiques une partie infime, mais mesurable, du carbone atmosphérique est transformé en carbone radioactif. Du fait de la chaîne alimentaire, ce carbone radioactif se retrouve dans les os des animaux. Dès que ceux-ci meurent, l'assimilation cesse et le carbone radioactif perd sa radioactivité. Elle décroît de moitié tous les 5 730 ans. On peut dater une objet organique en mesurant la radioactivité résiduelle. La précision de la mesure repose sur l'hypothèse d’une proportion constante de carbone radioactif dans l'atmosphère. 4, record 5, French, - m%C3%A9thode%20du%20carbone%2014
