Awild-type fruit fly (heterozygous for gray body color and red eyes) is mated with a black fruit fly with purple eyes. the offspring are wild-type, 721; black-purple, 751; gray-purple, 49; black-red, 45. what is the recombination frequency between these genes for body color and eye color? using information from problem 3, what fruit flies (genotypes and phenotypes) would you mate to determine the order of the body-color, wing-size, and eye-color genes on the chromosome?

Try and make the question more clear : )

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.

They are both used to view parts of the cell
