A conservation ecologist is studying Pacific Green Sea Turtles. One population is based on a remote island in the Indo-pacific that has very little tourist or human activity. The other population is on the coast of Australia and deals with more consequences of human activity. The ecologist has taken counts of the number of eggs in each female’s nest at both locations to evaluate the reproductive success. Is there a statistically significant difference between the two populations? What conclusion can you draw from this information? (5 points, 2 for answer, and 3 for showing work)

(see chapters 3 and 4, infection and passive immunity.) 2. explain how acute necrotizing fasciitis developed in this case and the pathophysiology involved. (see acute necrotizing fasciitis.) 3. what is the potential outcome for ms. w if antibiotic drugs do not reduce the infection quickly?
