Ques: Answer the following question given this paragraph: The modern day formulation of gun powder is called black powder. It is still commonly used today. Its formulation is still quite similar to what was used in 9 th century China. Black powder is considered a low explosive. It is a mixture that burns quickly, but the resulting shock wave travels at subsonic speeds. The speed at which it burns is dependent on the accessibility of oxygen atoms to the carbon source. In contrast, high explosives like nitroglycerin detonate instead of burning, creating shock waves that are supersonic (faster than the speed of sound). Q: High explosives create shock waves that exceed the speed of sound, a phenomenon that goes by what term? Choices: - light speed - ion speed - turbulence - supersonic A:
Ans: supersonic

Ques: Answer the following question given this paragraph: Organisms evolve adaptations that help them survive in the climate of the biome where they live. For example, in biomes with arid climates, plants may have special tissues for storing water (see Figure below ). The desert animals pictured in Figure below also have adaptations for a dry climate. Q: A plant that forms special tissues for storing water in an arid climate is an example of the plant evolving what? Choices: - consciousness - additions - divergence - adaptations A:
Ans: adaptations
