Earth science it is multiple questions. what determines the type of fossil formed a.) the conditions under which the organism was metamorphosed and how it was buried. b.) the conditions under which the organism died and how it lived. c.) the conditions under which the organism died and how it was buried. d.) the conditions under which the organism how it lived and how it was buried. question 2 organisms with hard parts stand a good chance of being fossilized if they are? a.) rapidly composed by bacteria. b.)slowly buried by sediments. c.) rapidly eaten by scavengers. d.) rapidly buried by sediments

Question 1 is C. and Question 2 is B.    (hope this helped)

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.
