Answer the following question given this paragraph: Fruits may be classified as simple, aggregate, multiple, or accessory, depending on their origin (Figure 32.22). If the fruit develops from a single carpel or fused carpels of a single ovary, it is known as a simple fruit, as seen in nuts and beans. An aggregate fruit is one that develops from more than one carpel, but all are in the same flower: the mature carpels fuse together to form the entire fruit, as seen in the raspberry. Multiple fruit develops from an inflorescence or a cluster of flowers. An example is the pineapple, where the flowers fuse together to form the fruit. Accessory fruits (sometimes called false fruits) are not derived from the ovary, but from another part of the flower, such as the receptacle (strawberry) or the hypanthium (apples and pears). Q: What plant products may be classified as simple, aggregate, multiple, or accessory, depending on their origin? Choices: - flowers - pods - leaves - fruits A:
fruits

Answer the following question given this paragraph: A rock under enough stress will fracture. There may or may not be movement along the fracture. If there is not movement, the fracture is a joint. If there is movement, the fracture is a fault. Q: What will happen to a rock when it's under tremendous stress? Choices: - it will slow - it will solidify - it will rebound - it will fracture A:
it will fracture

Answer the following question given this paragraph: Objects in motion that return to the same position after a fixed period of time are said to be in harmonic motion. Objects in harmonic motion have the ability to transfer some of their energy over large distances. They do so by creating waves in a medium. Imagine pushing up and down on the surface of a bathtub filled with water. Water acts as the medium that carries energy from your hand to the edges of the bathtub. Waves transfer energy over a distance without direct contact with the initial source. Since waves are disturbances in an existing medium, they are considered phenomena and not actual objects. Q: Objects in motion that return to the same position after a fixed period of time are said to be in what? Choices: - resonant motion - kinetic motion - homeostasis - harmonic motion A:
harmonic motion
