The Major Components of Life
Prokaryotic and eukaryotic are the two major categories of cells making up life on earth. Both these types require water and carbon.
Describe the characteristics of water and carbon that makes them important to living things in general, and to specific forms of life including plants, animals, and prokaryotes. Why is NASA looking for water on Mars?
Describe the differences in prokaryotic and eukaryotic cells. How have the characteristics of each kind of cell put limitations and provided opportunities for the survival and divergence of modern living things? Why might both cell types be considered equally successful? Make sure to consider both Domains of Prokaryotes.
The essay must be informed by the textbook.

Studies on the effects of food additives, in particular artificial food dyes such as Red-40, Yellow-5, and Blue-2, have been conducted since the 1970’s. The results of these investigations show that some additives can cause cancer or influence other conditions (e.g., allergies, asthma) in animal models. Despite the evidence, these findings have been discounted in most major countries. Critics suggest that the history of food additives is cause for concern, and that some of these decisions are made in the interests of multi-billion dollar food industries. Proponents argue that testing of food additives is already sufficient.
Task: Investigate the effects of consumption of artificial food dyes on adults and children. When investigating any contentious issue, you always should read through each website’s “About Us” link to help you understand their mission and identify potential biases and agendas. With that said, a good place to start is the website for the Center for Science the Public Interest (opens window). Your goal is to answer the following questions (be sure to number each answer so it is clear which question you answering):
Should food dyes be outlawed in the US? Why or why not?
Will you try to avoid them in the future? If so, how will you do this?
Remember to include the resources you used in your research and thoroughly explain your opinion. Be sure to cite and reference your sources in APA format
