Plan a Tilapia Farm Tilapia are the world's second most important
aquaculture, or farm-raised seafood product. Only
carp is raised in greater numbers. As a tilapia
farmer, you want to maximize the production of
your fishery. So you plan to perform experiments to
test the growth and survival rates of tilapia under
different conditions. In each test, only the
experimental variable will be changed. All other
variables will remain constant.

What is the dependent and independent variables and what sources of error that could have affected the results of the experiment. How could those error be avoided.

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.
