Question: Q: What sound can be heard when sound waves bounce back from a hard object? Read this paragraph and choose the correct option from the provided answers: Did you ever hear an echo of your own voice? An echo occurs when sound waves bounce back from a hard object. The man in Figure below is trying to create an echo by shouting toward a rock wall. When the sound waves strike the rock wall, they can't pass through. Instead, they bounce back toward the man, and he hears an echo of his voice. An echo is just one example of how waves interact with matter. Choices: - loop - eerie - boom - echo A:
Answer: echo

Question: Q: What are major temperature zones primarily based on? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - altitude - longitude - gps - latitute A:
Answer: latitute

Question: Q: When substances pass through the cell membrane without needing any energy what is it called? Read this paragraph and choose the correct option from the provided answers: Passive transport occurs when a substance passes through the cell membrane without needing any energy to pass through. This happens when a substance moves from an area where it is more concentrated to an area where it is less concentrated. Concentration is the number of particles of a substance in a given volume. Let's say you dissolve a teaspoon of salt in a cup of water. Then you dissolve two teaspoons of salt in another cup of water. The second solution will have a higher concentration of salt. Choices: - active transport - kinetic transport - energetic transport - passive transport A:
Answer:
passive transport
