1.Why might a biologist be interested in comparing the amino acid sequence of proteins between two different species? What differences might she find when comparing species that are distantly related or closely related? Explain.
2.Trans-fatty acids are a type of unsaturated fat. Most trans-fats consumed today are industrially created as a side effect of partial hydrogenation of plant oils (Crisco). In trans-fat molecules, the hydrogens on the doubly bonded carbon atoms (characteristic of all unsaturated fats) are straighter, rather than kinked, in shape. This straightening produces an unnatural molecule. Why do you think trans-fats are considered unhealthy as compared to other unsaturated fats? Can you explain your answer chemically?
3.Most adult humans lose the ability to digest dairy products, a condition known as lactose-intolerance because of an inactivity of the lactase enzyme for digestion. However, there is a high degree of lactose tolerant people who are from northern European descent. How can you explain lactose tolerance from a chemical perspective and why would there be a greater frequency from northern Europe?
4.Epulos, a bacterium growing in the gut of tropical surgeon fish can reach the size of 500 micrometers. How does this compare to other bacteria and what problems does this present the epulos? What are some ways that a cell this size could alter its structure to survive?

For Step 1, choose a topic of sociological interest. Be sure to include why you chose the topic and why it would be interesting to sociologists. So, don’t just choose something obvious like “Cigarettes and health.” Everybody already knows about that. Choose something that merits actually doing research. Remember, sociologists are interested in the relationship between individuals and society. So, a topic like, Green leaf vegetables and cancer, while both important and interesting, is not really a sociological study, but more like health sciences or nutrition. For more help, refer to YMAY pages 35-40
For Step 2, think about and compose a specific research question that emerges from your general topic of interest. Then, create a falsifiable hypothesis about how the relationship in your research question might function. Make sure your hypothesis is a testable statement (not a question) that could be determined to be false at the conclusion of your research (if it were to actually be conducted). Based on your hypothesis, you should come up with and clearly identify at least one dependent and one independent variable. These variables must appear in your hypothesis. You should also identify at least one control variable that might affect your results, and explain how this control variable may affect the relationship between your independent and dependent variables.
For Step 3, describe your target population and type of study. That is, tell me who or what exactly is going to be in your study and how you would go about getting access to this group. At this point, it is also important to think about what type of sample you will collect and whether you will be able to generalize findings from your sample to your population.
