2. You are conducting an experiment to determine if increased predation, water pollution, or ultraviolet radiation from the decrease in the ozone layer is killing off frog tadpoles of a particular species in a given population. After examining all of the data available in the library, you decide to go with a hypothesis that increased UV radiation is responsible. a. Outline an experiment with a control and an experimental group. Be sure to list all factors you need to control to rule out possibilities other than radiation. b. What would missing tadpoles vs. present but dead tadpoles in your treatment tell you? c. How would you decide how long to run the experiment? Be sure to identify variables measured and those implemented to provide alternate treatments.
