Document Summary
Answers to end-of-chapter study questions by richard w. hill to accompany. Chapter 1: animals and environments: function on the ecological stage: there is a chance that a calcium atom or carbon atom that was once part of caesar"s or. Cleopatra"s body is now part of your body. Part of the reason is that most calcium and carbon atoms that were parts of these rulers" bodies did not go to their graves with them. Explain both statements. (if you enjoy quantifying processes, also see question 11. ) Answer: animals exchange atoms with their environments throughout their lives. Thus, over the decades of caesar"s life, numerous atoms that were part of his body had returned to the environment. Thus they depend on phenotypic plasticity to adapt to changing hazards. An example is provided by the enzyme alcohol dehydrogenase, which breaks down ethyl alcohol. People who do not drink alcoholic beverages have little alcohol dehydrogenase.
