Because the animal food chain ultimately relies on the sugars and organic compounds produced by plants, the ratio of 12CO2 to 14CO2 incorporated into animal tissues (e.g., bone) and organs should also be the same as that present in the atmosphere. True or False? - True During photosynthesis, plants incorporate carbon dioxide into sugars and other organic compounds. The ratio of 12CO2 to 14CO2 incorporated into the sugars and other organic compounds should be equivalent to the ratio present ...

How do nuclear gauges work? Why does so much care need to be taken when using them? - AnswerNuclear gauges use the interaction of radiation with matter to measure the density and moisture of material. Radiation sources within each gauge transmit radiation through the test material. Detectors contained in the gauge measure the radiation that is scattered by the test material or that passes through it. By calculating the percentage of radiation that reaches the detectors, the gauge can determi...
