Aperson eats a large pasta meal at lunch and then goes for a run before dinner. explain how the body taps energy from this starchy meal

Fuel for the human body takes three basic forms: carbohydrates (sugars), protein, and fat. Humans are capable of burning all three of these fuels, but do so at different times, rates, and under different circumstances. Using an extreme example, under starvation conditions the body burns its fat stores. Once fat stores are depleted the body begins digesting non-essential proteins and then finally essential proteins, which ultimately leads to organ damage and death. Thankfully, the body is efficient and uses the best available fuel first before it has to tap into essential reserves.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
