The false statement about the digestive system is C. Food enters the large intestine before the small intestine.

In the digestive system, there's a ring consisting of smooth muscle called the pyloric sphincter. This separates the stomach from the small intestine. It functions in controlling movement of chyme.

Chyme, on the other hand, are partially digested food that is mixed with digestive juices in the stomach.

Therefore, statement A and B are TRUE.

Statement D is also true because the chyme is passed over to the small intestine to mix with bile. However, food passes through the small intestine before coming to the big intestine.

Therefore, the statement "C. Food enters the large intestine before the small intestine" is FALSE.

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.
