Answer the following question given this paragraph: When a new air mass moves over a region it brings its characteristics to the region. This may change the area's temperature and humidity. Moving air masses cause the weather to change when they contact different conditions. For example, a warm air mass moving over cold ground may cause an inversion. Q: An inversion may result when what kind of mass moves over cold ground? Choices: - warm water - cold water - cold air - warm air A:
warm air
Answer the following question given this paragraph: Most mature plant cells have a large central vacuole . This vacuole can make up as much as 90% of the cell's volume. The central vacuole has a number of functions, including storing substances such as water, enzymes, and salts. It also helps plant tissues, such as stems and leaves, stay rigid and hold their shape. It even helps give flowers, like the ones in Figure below , their beautiful colors. Q: What part of a mature plant cell is responsible for storing substances like water, enzymes, and salts? Choices: - little vacuole - second vacuole - large vacuole - central vacuole A:
central vacuole
Q: Answer the following question given this paragraph: This inverse relationship between solubility and temperature can be understood by looking at a molecular model. Recall that higher temperatures are associated with faster particles. Gas particles are held in solution by attractive interactions with the solvent molecules. If the particles are moving slowly, these attractive forces will pull back any particles that try to escape the surface of the solution and re-enter the gas phase. However, if the gas particles are moving fast enough, these interactions will not be sufficiently strong to prevent this process from occurring. As a result, more particles are able to escape, and the amount of dissolved solute is less than it would be at a lower temperature. Q: This inverse relationship between solubility and temperature can be understood by looking at a what? Choices: - nutrient model - a slide - potassium model - molecular model A:
A: molecular model
Question: Answer the following question given this paragraph: The problem doesn't stop with plowing. Crops are usually planted in rows, with bare soil in between the rows. In places where crops grow only during part of the year, the land may be bare for a few months. Q: In places where crops grow only during part of the year, the land may be bare for a few? Choices: - days - weeks - minutes - months A:
Answer: months

Answer the following question given this paragraph: Sedimentary rocks form when sediments are compacted and cemented together. Sediments are pieces of rock. They may be gravel, sand, silt, or clay. Some sedimentary rocks form the solid minerals left behind after a liquid evaporates. Q: What type of rocks form when sediments are compacted and cemented together? Choices: - metamorphic rocks - crystalline rocks - igneous rocks - sedimentary rocks A:
**Answer**
sedimentary rocks
Answer the following question given this paragraph: Wave interference occurs when waves interact with other waves. Constructive interference increases wave amplitude. Destructive interference decreases wave amplitude. Q: What occurs when waves interact with other waves? Choices: - resurgence - vibration - frequency - interference A:
interference
