Frogs and toads undergo complete metamorphosis to change from water-dependent tadpoles to Sand-bound adults. Scientists working with two species of toads (A and B) notice that Species A takes 9 days from egg to adulthood, while Species B takes about 3 weeks to complete the process.
a. Josh claims that Species A most likely lives in the desert, where water supply is scarce, and it would be an advantage to get to adulthood quickly. Is he
correct? Explain your answer.
b. Scientists do a "water drop" experiment on Species B, where they place Species in a full tank of water for a week, then drain 75% of the water to
simulate pond-drying. After the water drop, it took Species B twelve days to reach adulthood from a fertilized egg. Describe why the ability to change
metamorphosis speed is an advantage for Species B.
