Question 9

Mike has classical hemophilia,a clotting disorder,but his case is considered "mild." Contrary to popular belief,Mike doesn't usually have problematic bleeding episodes related to cutting himself; a more severe problem for him would be brought on by a sprained ankle or by having a full body impact,like falling off a horse and landing hard on the ground,injuries considered "closed." With what you have learned about blood coagulation,can you explain how this could be so? Assuming Mike is lacking factor VIII,which pathways does he depend on?

Question 17

A study was done in 1998 by Dr.Benjamin Levine to explore the role of altitude training in athletic performance.First he trained athletes at low altitude,then measured their finish times in a 5 kilometer run.Then the athletes were placed into one of the following groups: I,living and training at high altitude; II,living at high altitude and training at low; or III,living and training at low altitude.The athletes were then retested in another low-altitude 5 K race.In this study,what are the control and experimental data? What are the dependent and independent variables? The results are expressed as average change in speed of each group.I: -3.4 sec.,II: +13.4 sec.,III: -26.7 sec.Graph and interpret the results.Did the results surprise you? Why or why not? Propose some explanations for the lower performance by the live high-train high group.Why wasn't there a live low-train high group?
