In a species of fish, fin shape is controlled by a single gene that has only two alleles. In a generation of 185 fish, the frequency of the recessive allele is 0.25. After six generations, the recessive allele frequency in a population of 230 fish is 0.43. Which of the following does this most likely indicate about the dominant and recessive alleles?

The answer is magnitude measures the effects of an earthquake on the area , while the intensity measures the strength of an earthquake.

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.
