vaccination information. clicking the box flu basics will take you to a new page, with seasonal flu
basics categories highlighted on the left. use the information in this section to write a statement of one

• what causes the flu?
• what are common symptoms of the flu and what are complications that arise from the disease?
• do you think people can misdiagnose themselves with the flu? explain your reasoning.
• how is flu season defined? what are the criteria for this definition?
• how does the flu affect businesses and governments? could it affect residents' access to certain

We can use solar powered cars or ride bikes instead of cars that burn fossil fuels

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.
