Q: Q: A desert is a type of what community in an ecosystem? Read this paragraph and choose the correct option from the provided answers: This scene is from Anza-Borrago California Desert Park. However, deserts exist around the globe. You might find a similar picture of a desert in Africa. The desert is one type of biome. Choices: - culture - population - colony - biome A:
A: biome

Q: Q: What do you call the ability to sense sound energy and perceive sound? Read this paragraph and choose the correct option from the provided answers: Hearing is the ability to sense sound energy and perceive sound. The ear is the organ that senses sound and allows us to hear. Damage to structures of the ear may cause hearing loss. Total hearing loss is called deafness. Choices: - tuning - sensory deprivation - echolocation - hearing A:
A: hearing

Q: Q: The actual amount (mass) of gasoline left in the tank when the gauge hits "empty" is a lot less in the summer than in the winter. the gasoline has the same volume as it does in the winter when the "add fuel" light goes on, but because the gasoline has expanded, there is what? Read this paragraph and choose the correct option from the provided answers: Making Connections: Real-World ConnectionsFilling the Tank Differences in the thermal expansion of materials can lead to interesting effects at the gas station. One example is the dripping of gasoline from a freshly filled tank on a hot day. Gasoline starts out at the temperature of the ground under the gas station, which is cooler than the air temperature above. The gasoline cools the steel tank when it is filled. Both gasoline and steel tank expand as they warm to air temperature, but gasoline expands much more than steel, and so it may overflow. This difference in expansion can also cause problems when interpreting the gasoline gauge. The actual amount (mass) of gasoline left in the tank when the gauge hits "empty" is a lot less in the summer than in the winter. The gasoline has the same volume as it does in the winter when the "add fuel" light goes on, but because the gasoline has expanded, there is less mass. If you are used to getting another 40 miles on "empty" in the winter, bewareyou will probably run out much more quickly in the summer. Choices: - lower gravity - same mass - more mass - less mass A:
A: less mass

Q: Q: What technology do scientists use to create models? Read this paragraph and choose the correct option from the provided answers: Scientists create models with computers. Computers can handle enormous amounts of data. This can more accurately represent the real situation. For example, Earth's climate depends on an enormous number of factors. Climate models can predict how climate will change as certain gases are added to the atmosphere. To test how good a model is, scientists might start a test run at a time in the past. If the model can predict the present it is probably a good model. It is more likely to be accurate when predicting the future. Choices: - calculators - patterns - microscopes - computers A:
A: computers
