Territorial claims to Antarctica are unresolved

5. Conservation tillage is an agricultural practice that A. Maximizes intact ground cover to prevent soil erosion B. Conserves all native grasses in order to promote intact ecosystems C. Removes all weeds and competing plants in order to maximize crop yields D. Promotes polyculture, including cattle grazing, to naturally fertilize fields E.

New strains of GMO seeds that might cause human health problems C. The overabundance of food produced, leading to unusually low food prices D. The necessity for seed banks, now that we are using so many varied seeds to grow crops worldwide E. New strains of GMO seeds that have transgenes, whichmay escape into nature, causing unknown and possibly harmful effects

Which of the following is most likely to be the direct result of lack of genetic diversity in a food crop such as corn? A. Decreased dependence on chemical fertilizers B. Increased resistance to pests C. Decreased kernel size D. Decreased number of people fed E. Increased susceptibility to plant disease

9. Which of the following is an environmental problem associated with abandoned coal mines? A. Air pollution caused by smog from ozone formation B. Alkaline solutions that pollute streams C. Acid drainage due to leaching of spoil heaps by rain water D. Released nutrients that cause eutrophication in to streams E. Thermal pollution of streams in the area

10. Which of the following procedures would be best for remediating the effects of soil salinization? A. Adding pools of water to soak into the soil, removing the salt from the surface B. Application of superphosphate to increase soil fertility C. Addition of clay to increase soil water holding capacity D.
