1. Charles Darwin once described a flower that produced nectar at the bottom of a tube 25 centimeters (10.5 inches) deep. He predicated that there must be a moth or other animal with a 25-centimeters-long tongue to match, and he was right. Such specilization almost certainly means that this particular flower could be pollinated only by that specific moth. What are the advantages and disadvantages of such specialization?
2. Agent Orange, a combination of two synthetic auxins, was used in Vietnam to defoliate the rain forest during the Vietnam War. Being similiar to natural growth hormones, how can synthetic auxins harm or kill plants? What do you think would happen if natural auxins were used in excess quantities on plants?
