Q: Like the strings of cello, anything that vibrates produces waves of what? Read this paragraph and choose the correct option from the provided answers: A: Like the strings of cello, anything that vibrates produces waves of energy that travel through matter. For example, when you throw a pebble into a pond, waves of energy travel from the pebble through the water in all directions. Like an incandescent light bulb, anything that glows consists of matter that produces light energy. For example, fireflies use chemicals to produce light energy. Like a moving tennis racket, anything that moves has energy because it is moving, including your eyes as they read this sentence. Choices: - heating - light - sound - energy A:
energy

Q: What plant hormone allows plants to curve in a specific direction? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - peptides - pheremone - apoptosis - auxin A:
auxin
