32. A graduate student injects 10 mice with a chemical compound commonly found in the environment and finds that all of his animals die within a few days. Eager to publish his results, the student comes to you, his adviser. What would you suggest the student do before publishing his results? Help him design a controlled experiment. State a good hypothesis, describe the experiment, identify the control group, independent, dependent and controlled variables.

33.The brown bracts of the plant Monotropsisodorata resemble leaf litter, which affords them protection from predators. Describe four characteristics of life you could identify to distinguish these plants from the dead leaves they mimic.
34. At the beginning of the spring, Dr. Alice Whittlesby notices that there is an equal distribution of long and short stemmed buttercups in the vacant lot across the street from her house as well as in her own backward. By the end of the summer she notes that there are mostly long stemmed buttercups in the lot, but mostly short stemmed buttercups in her yard. These observations are examples of what biological principle? Develop a hypothesis to explain Dr. Whittlesby’s observations.
