A protocol is required for each of the two situations presented below; determine which participant(s) is responsible for providing the protocol, SOP, consent forms, approvals, etc. for a proposed study of the problem. In other words, what is each participant required to provide in the way of paperwork. (In this context, participant may be an individual or it may be a laboratory, organization, or collaborators in a study.) Please to be sure to briefly describe what information should be included.
1. During the last five years, the alligator population has diminished significantly in Lake Apopka. It has been postulated that pesticides used in the area accumulate in alligator eggs thereby causing a reduced birth rate. In order to study this problem, the principal investigator will collect the alligator eggs and give them to the departmental GC/MS laboratory that will determine the levels of pesticides in the egg yolks. Using this data, the investigator will see if there is a correlation between alligator population and pesticide usage. (10 points)
2. Ace Pharmaceutical Company is developing a new antihypertensive drug that has been found to lower hypertension and has low toxicity in rats. At this point, Ace plans to initiate studies on the effect of the drug on monkeys at several universities. If results from these animal studies show promise, clinical studies will be initiated at five sites. (10 points)

The data above was obtained from an area of blood spatter from the crime scene case study addressed in earlier modules.
This group of 6 blood stains all showed a single point of convergence. Using this data:
- Calculate the angle of impact for each stain (6pts)
- Use the following equation (see module notes), tan I = H/D, to determine the Height of Origin (inches) for each stain (6 pts)
- Based on the Height of Origin of each stain, how many different events do you think occurred? (2 pts)
- Using the information from 1-3, develop a scenario that may describe what happened. Considering the heights of the points of origin and the fact that the victim was delivered blows to the head and abdomen area – what does this tell you about the position of the body when the blows to the head and abdomen occurred [6 pts
