Anot very well-studied a& p student heard about a phenomenon called water intoxication and thought it sounded fun so she decided to try it. she consumed a large amount of water in a short time (don't try this—water intoxication is often instead of feeling drunk, she felt nauseated, developed a severe headache, began to get confused, and then became unconscious. her much more prepared a& p student roommate quickly realized the problem and called an ambulance. when the roommate told the emergency department doctor what had happened, the doctor quickly began administering iv (intravenous) fluids.
based on this information and your understanding of osmosis and tonicity, what type of iv fluid is the doctor likely administering to try to save the life of the student suffering from water intoxication?

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.

Iam not sure but to me it with be a or dsorry if i was late! hope this ! : )if you really want me to find out the answer that is correct tell me and i will do more research but the a or d makes sense to me.

An ecosystem is in a certain area and includes living and non living plus there is weather conditions and a biome is a large amount of area with similar climate.so ecosystem is based on weather and biome is based on the average climate 

Distillation.  distillation is the correct answer.
