Suppose scientists study mutant bacterial strains of staphylococcus aureus to find the order of the genes for tetracycline resistance (gene t), streptomycin resistance (gene s), erythromycin resistance (gene e), and penicillin resistance (gene p). they extract dna from bacterial strains with one or more of these mutations and transform wild‑type bacterial cells (s+, e+, t+, p+) with the dna. given that the p mutation is first, indicate the order of these bacterial genes within the genome according to the transformation experiment results.

They both have rock surfaces

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.

The answer is c) organisms that are sensitive to changes in temperature would die.
