bacteria and archaebacteria

Explanation:

Initially, all of the bacteria has been classified in the same kingdom, monera. The main reason for this was that when this classification was made, the scientists only had so much information about the bacteria that it seemed to them that they are all part of the same kingdom. As the technology developed and enabled the scientists to study the bacteria much better and in much greater detail, it turned out that the classification was wrong. A new classification then came out which separated the bacteria into two kingdoms, bacteria, and archaebacteria based on their characteristics of course.

Answer from: Quest

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.
