Answer the following question given this paragraph: Weather is always changing. One day might be cold and cloudy. The next day might be warm and sunny. Even on the same day, the weather can change a lot. A beautiful morning might be followed by a stormy afternoon. Why does weather change? The main reason is moving air masses. Q: What is the main reason for weather change? Choices: - climate change - moving energy masses - seasons - moving air masses A:
moving air masses
Answer the following question given this paragraph: Temperature falls from the equator to the poles. Therefore, major temperature zones are based on latitude. They include tropical, temperate, and arctic zones (see Figure below ). However, other factors besides latitude may also influence temperature. For example, land near the ocean may have cooler summers and warmer winters than land farther inland. This is because water gains and loses heat more slowly than does land, and the water temperature influences the temperature on the coast. Temperature also falls from lower to higher altitudes. That's why tropical zone mountain tops may be capped with snow. Q: Water gains and loses what more slowly than does land, affecting seasonal conditions inland and on the coast? Choices: - volume - humidity - minerals - heat A:
heat
Q: Answer the following question given this paragraph: Water density increases as salinity and pressure increase, or as temperature decreases. Q: When salinity and pressure increase, or when temperature decreases, what happens to water density? Choices: - fluctuates - drops - stays the same - increases A:
A: increases
Question: Answer the following question given this paragraph: Cells divide repeatedly to produce an embryo. Previously the one-celled zygote (the first cell of a new organism) divided to make two cells (a). Each of the two cells divides to yield four cells (b), then the four cells divide to make eight cells (c), and so on. Through cell division, an entire embryo forms from one initial cell. Q: What do you call the first cell of a new organism? Choices: - embryo - starter cell - egg - zygote A:
Answer: zygote

Q: Answer the following question given this paragraph: fossils and birds, specifically in the structure of the hip and wrist bones, as well as the presence of the wishbone, formed by the fusing of the clavicles. One important fossil of an animal intermediate to dinosaurs and birds is Archaeopteryx, which is from the Jurassic period (Figure 29.33). Archaeopteryx is important in establishing the relationship between birds and dinosaurs, because it is an intermediate fossil, meaning it has characteristics of both dinosaurs and birds. Some scientists propose classifying it as a bird, but others prefer to classify it as a dinosaur. The fossilized skeleton of Archaeopteryx looks like that of a dinosaur, and it had teeth whereas birds do not, but it also had feathers modified for flight, a trait associated only with birds among modern animals. Fossils of older feathered dinosaurs exist, but the feathers do not have the characteristics of flight feathers. Q: The fossilized skeleton of archaeopteryx looks like that of a dinosaur, but it had what structures modified for flight, a trait associated only with birds among modern animals? Choices: - fingers - claws - beaks - feathers A:
A: feathers
