Astudent is investigating the role diffusion plays in maintaining homeostasis inside of animal cells. the student plans to place a starch solution inside of a container and place a glucose solution inside of a second container. the student will then place each container into a beaker of distilled water. after 20 minutes, the student will test the water in each beaker for the presence of starch and glucose. which of the following would be the best material for the student to use for the containers holding the glucose and starch solutions? a rubber balloon that can expand and stretch without breaking b tissue paper that will easily rip and dissolve in water c tubing with many pores that are too small to see d glass that has a flat and uniform surface

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.
