Answer the following question given this paragraph: A tornado only strikes a small area. But it can destroy everything in its path. Most injuries and deaths from tornadoes are caused by flying debris ( Figure below ). In the United States, an average of 90 people are killed by tornadoes each year. The most violent two percent of tornadoes account for 70% of the deaths by tornadoes. Q: What consequence of a tornado is responsible for most injuries and deaths? Choices: - catching debris - touring debris - falling debris - flying debris A:
flying debris
Answer the following question given this paragraph: A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O 2 as one reactant. The combustion of hydrogen gas produces water vapor. Q: What chemical element is required for a combustion reaction ? Choices: - carbon - helium - nitrogen - oxygen A:
oxygen
Q: Answer the following question given this paragraph: The lowest latitudes get the most energy from the Sun. The highest latitudes get the least. Q: Which latitudes get the most energy from the sun? Choices: - middle latitudes - highest latitudes - polular latitudes - lowest latitudes A:
A: lowest latitudes
Question: Answer the following question given this paragraph: Crystalline solids have particles that are arranged in a regular repeating pattern. They form crystals. Amorphous solids have particles that are arranged more-or-less at random. They do not form crystals. Q: What kind of solids have particles that are arranged in a regular repeating pattern? Choices: - carbon-based solids - salts - metabolic solids - crystalline solids A:
Answer: crystalline solids

Answer the following question given this paragraph: There are three main ocean zones based on distance from shore. They are the intertidal zone , neritic zone , and oceanic zone . Distance from shore influences how many nutrients are in the water. Why? Most nutrients are washed into ocean water from land. Therefore, water closer to shore tends to have more nutrients. Living things need nutrients. So distance from shore also influences how many organisms live in the water. Q: What do living things need to survive? Choices: - oxygen - heat - molecules - nutrients A:
**Answer**
nutrients

Answer the following question given this paragraph: Note The carbonyl group is ubiquitous in biological compounds. It is found in carbohydrates, fats, proteins, nucleic acids, hormones, and vitaminsorganic compounds critical to living systems. In a ketone, two carbon groups are attached to the carbonyl carbon atom. The following general formulas, in which R represents an alkyl group and Ar stands for an aryl group, represent ketones. Q: In a ketone, two of which kind of groups are attached to the carbonyl carbon atom? Choices: - ions - nitrogen groups - oxygen groups - carbon groups A:
**Answer**
carbon groups
