1 GMOs Advantages If properly regulated Remove/prevent disease in some foods Food can be designed to last longer on the shelf; less waste Convenience Improve the nutritional value of some foods Disadvantages Doesn’t actually increase yields (over time, destroys fields) Encourage the use of herbicides and pesticides (round-up ready seeds) Contracts between farmers and Monsanto don’t allow crop circulation or to keep seeds; seeds are engineered to not produce more seeds Bad effects on the body (carcinogens=cancer-causing agent, birth defects) Engineered genes can be passed to other organisms (superweeds) Organic farms near farms that use GMOs - genes transferred to their crops

2 A species of malaria-carrying mosquito lives in a forest in which two species of monkeys, A and B, coexist. Species A is resistant to malaria, but species B is not. The malaria-carrying mosquito is the chief food for a particular kind of bird in the forest. If all these birds were suddenly eliminated by hunters, which of the following would be an immediately observable consequence? (HINT: Draw out a diagram and Consider how the elimination of the mosquito- eating bird would affect the mosquito population.) A.Increased mortality (death rate) in monkey species A B.Increased mortality in monkey species B C.Increased mortality in the malaria-carrying mosquitoes D.Emergence of malaria-resistant strains in monkey species B E.Emergence of malaria-sensitive strains in monkey species A Solution on next slide
