Astudent designs an experiment to see if detergent affects the growth of seeds. he sets up 10 seed pots. five of the seed pots will receive a small amount of detergent in the soil and will be placed in the shade. the other five seed pots will not receive detergent and will be placed in the sun. all 10 seed pots will receive the same amount of water, the same number of seeds, and the same type of seeds. he allows the seeds to grow for two months and charts their growth every two days. what is wrong with his experiment ?

a) more than one variable is being tested.

b) the student should have a larger amount of pots.

c) there is no way of measuring the outcome

d) there in no control set up.

Its b im pretty sure the students should have larger amounts

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.
