Q: What happened to earth's species during the permian period? Read this paragraph and choose the correct option from the provided answers: The Permian Period ended with Earth's second mass extinction. During this event, most of Earth's species went extinct. It was the most massive extinction ever recorded. It's not clear why it happened. One possible reason is that a very large meteorite struck Earth. Another possibility is the eruption of enormous volcanoes. Either event could create a huge amount of dust. The dust might block out sunlight for months. This would cool the planet and prevent photosynthesis. Choices: - evolution - duplication - division - mass extinction A:
mass extinction

Q: The heat capacity of an object depends on its chemical composition and what other property? Read this paragraph and choose the correct option from the provided answers: If a swimming pool and wading, both full of water at the same temperature were subjected to the same input of heat energy, the wading pool would certainly rise in temperature more quickly than the swimming pool. The heat capacity of an object depends both on its mass and its chemical composition. Because of its much larger mass, the swimming pool of water has a larger heat capacity than the bucket of water. Choices: - volume - concentrations - weight - mass A:
mass

Q: What is the name of the zone where water is deeper than 200 meters called? Read this paragraph and choose the correct option from the provided answers: The aphotic zone is water deeper than 200 meters. This is where too little sunlight penetrates for photosynthesis to occur. As a result, producers must make "food" by chemosynthesis , or the food must drift down from the water above. Choices: - transition zone - euphotic zone - eccentric zone - aphotic zone A:
aphotic zone
