Answer the following question given this paragraph: Moving water has energy ( Figure above ). That energy is used to make electricity. Hydroelectric power , or hydropower, harnesses the energy of water moving down a stream. Hydropower is the most widely used form of renewable energy in the world. This abundant energy source provides almost one fifth of the world's electricity. The energy of waves and tides can also be used to produce water power. At this time, wave and tidal power are rare. Q: What is the most widely used form of renewable energy in the world? Choices: - wind - fossil fuel - solar - hydropower A:

Q: Answer the following question given this paragraph: Plants may not be able to move to another location, but they are able to change how they grow in response to their environment. Growth toward or away from a stimulus is known as a tropism ( Table below ). Auxins, a class of plant hormones, allow plants to curve in specific directions as they grow. The auxin moves to one side of the stem, where it starts a chain of events that cause rapid cell growth on just that one side of the stem. With one side of the stem growing faster than the other, the plant begins to bend. Q: What plant hormone allows plants to curve in a specific direction? Choices: - peptides - pheremone - apoptosis - auxin A:
A: auxin
