A researcher inserted the human gene for the protein hemoglobin into a plasmid. The plasmid was taken up by a bacterial cell through the process of transformation. The bacterial cell utilized the gene to produce a protein. However, the protein did not have the same amino acid sequence as hemoglobin has in a human cell. In fact, the protein in the bacterial cell was much longer than in the human cell. How can you explain this?

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.

C. a mature ovule of a plant.

That is false even though water expands when frozen nothing changes at all
