Venoms nearly always consist of complex mixes of compounds.Suggest evolutionary and physiological reasons why mixes areemployed rather than pure compounds. Assume that mixes implylower amounts of individual components; for instance, assumethat if a venom is composed of two compounds, each will bepresent in only about half the quantity than if it were the onlycomponent.
