The snake was fed rabbits, which mimic its natural diet of medium-sized mammals. (Burmese pythons have been known to feed on animals as large as tigers, but usually eat smaller prey). Calculate the overall energy density of this food in kJ/g (recall class discussion) Whole rabbits contain approximately 23% protein, 11% fat, 0% carbohydrate, 10% indigestible material (bone, fur), and 56% water (similar to lean meat from a human nutrition book, with added indigestible material).

The answer is a: the eggs have half as many chromosomes as the body cells

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.

C) to ensure each new cell has an exact copy of the dna
