Once two populations of a species have become allopatric with some barrier preventing gene flow between them, the two populations are free to diverge genetically. One mechanism for divergence that is thought to result in rapid divergence is sexual selection. a. Why is sexual selection likely to result in more […]

A solution containing 3.45 mM of p-xylene (analyte) and 6.86 mM of nonane (standard) gave peak areas of 13587 and 14769 respectively, in a chromatographic analysis. then 1.5 mL of 6.86mM nonane solution was added to 5 mL of an unknown sample containing p-xylene. This solution gave peak areas of11875 […]
