A glass aquarium (sealed; closed system) is filled with water and contains plants and fish (the fish eat the plants). This aquarium is in the sunlight. The
amount of carbon dioxide in the water started out high (it is not being used up
yet.) Then, after a period of time, that amount of carbon dioxide started to
decrease (it was used up.) AFTER the decrease, are there FEWER or MORE glucose
molecules in the organisms?

Since a female is both xx chromosome and the male passes down the x chromosome, than the offspring would be female since a female is xx.

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.
