4) The graph below shows the relationship between the numbers of Ribeiroia parasites that tadpoles were exposed to and their rates of survival and deformity. Initial numbers of tadpoles were 35 in the control group (0 parasites) and 45 in each of the other three treatments. (After Johnson et al. 1999.) What can you conclude based upon these results? CIRCLE ONLY ONE LETTER A. The percentage of deformed frogs decreased as the number of parasites the tadpoles were exposed to increased B. Tadpole survivorship decreased as the number of parasites increased C. Parasites are responsible for the global decline in amphibians D. The experiment did not have a control E. Both B and D
