Some students are investigating the life cycle of the spotted salamander. They learn that these salamanders must live close to water and lay their eggs in water. After 20-60 days the eggs hatch as larvae that must stay in the water until they mature into adult salamanders. The students infer that the life cycle of the spotted salamander is similar to the life cycle of the frog because both animals---- (3.10B)

• have long tails and strong jumping legs as adults

• live near water and produce larvae with wings

• lay eggs in water, which hatch into larvae that live in water

• produce offspring that hatch from eggs and look like adults
