Answer the following question given this paragraph: Some maps have a double compass rose. This allows users to make the corrections between magnetic north and true north. An example is a nautical chart that boaters use to chart their positions at sea ( Figure below ). Q: Which feature in maps allows users to make corrections between magnetic north and true north? Choices: - inset - scale - key - double compass rose A:
double compass rose

Answer the following question given this paragraph: Most fossils form when a dead organism is buried in sediment. Layers of sediment slowly build up. The sediment is buried and turns into sedimentary rock. The remains inside the rock also turn to rock. The remains are replaced by minerals. The remains literally turn to stone. Fossilization is illustrated in Figure below . Q: Most fossils form when a dead organism is buried in what? Choices: - soil - ash - sand - sediment A:
sediment

Answer the following question given this paragraph: A meteoroid is dragged toward Earth by gravity and enters the atmosphere. Friction with the atmosphere heats the object quickly, so it starts to vaporize. As it flies through the atmosphere, it leaves a trail of glowing gases. The object is now a meteor. Most meteors vaporize in the atmosphere. They never reach Earth's surface. Large meteoroids may not burn up entirely in the atmosphere. A small core may remain and hit Earth's surface. This is called a meteorite . Q: What causes a meteoroid to vaporize after it enters the atmosphere? Choices: - gravitational pull - atmospheric pressure - spontaneous combustion - friction with atmosphere A:
friction with atmosphere

Answer the following question given this paragraph: Gas exchange is needed to provide cells with the oxygen they need for cellular respiration. Cells cannot survive for long without oxygen. Gas exchange is also needed to carry away carbon dioxide waste. Some of the carbon dioxide in the blood dissolves to form carbonic acid, which keeps blood pH within a normal range. Q: What is needed to provide cells with the oxygen they need for cellular respiration? Choices: - vascular tissue - passive transport - photosynthesis - gas exchange A:
gas exchange
