Customer Question

ESSAY SECTION

SECTION INSTRUCTIONS: Each question is worth 10 points4.During the past 50 years, more than 200 species of insects that attack crop plants have become highly resistant to DDT and other pesticides. Based on what you have learned in this class regarding evolution, explain the rapid and widespread evolution of resistance. Now that DDT has been banned in the US, what do you expect to happen to levels of resistance to DDT among insect populations?

5.Water is crucial for life as we know it. One of the most important characteristics of water is its ability to act as a solvent. Explain why water is such a good solvent for polar and charged molecules.

9. Describe the process of natural selection by explaining how a population of mosquitoes can become resistant to a pesticide (which was originally fatal to most of the population). You must include in your explanation these components of natural selection- individual variation, differential reproduction, and changes in allele frequencies.
