PROBLEM

52. Most of the major developmental events (for example, organ formation) occur during early pregnancy. Most miscarriages occur during this period. Fetal alcohol syndrome is due to alcohol use by pregnant women, especially during early pregnancy. Exposure to mutagens or drugs at this stage can cause serious damage to the embryo.

53. Bacteria are much larger than viruses
Bacteria replicate by binary fission while viruses must reproduce within the host cell

Webquest 5-16

We just watched a short video about coastal systems. Now you are going to embark on an exciting journey through our country’s Barrier Islands.

This is not like our normal webquest. Today your job is to develop an educated opinion as to whether or not people should build permanent structures on barrier islands. You will need to learn about the geological and physical nature of barrier islands, and how barrier islands change over time. You will look at development of barrier islands and find out how the beaches on these islands are maintained. You will find out how different states handle the protection or development of their barrier islands. You will also find out what happens to permanent structures that are built on barrier islands. Finally, you will form an opinion as to whether permanent structures should be built on barrier islands.

Once you have done your research, you will prepare an open letter to the editor of a newspaper in which you outline what you have learned about barrier islands and state your opinion on whether permanent structures should be built there. Your letter should include information about the geology and ecology of barrier islands as well as the changes they are subject to. Your goal is to convince readers of the newspaper that your conclusion is correct, and to encourage them to write to the appropriate agencies in support of your position.
