Ashopping mall wanted to determine whether the more expensive “tough stuff” floor wax was better than the traditional “steel seal” floor wax at protecting its floor tiles against scratches. one liter of the "tough stuff" floor wax was applied to five different 5 test sections of the main hall of the mall. the "steal seal" was also applied to five different test sections in the main hallway. the test sections were all the same size and were covered with the same kind of tiles. after 3 weeks, the number of scratches in each of the test sections was counted. the "tough stuff" sections had a total of 20 scratches while the steel seal sections had 36. control group(s) = experimental group(s) = indep. variable= dependent variable =

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.

A) the sequence of bases would halt the production of any proteins.
