Thomas is studying the daily electric power used by his town. He has summarized the power consumption of his town over the course of an average day in the graph below. Judging from his data, which of the following inferences could Thomas make? A. Consumption drastically decreases at 7:00 a. m. because this is when people go to sleep and turn off their electronic devices. B. Clothes driers and refrigerators require the greatest input of electricity in order to function. C. People in Thomas' town tend to use electricity at a constant rate over the course of most days. D. Consumption rapidly increases at 7:00 a. m. because this is when people wake up for work and school and turn on electrical devices.

Your answer will be b action plan.

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.
