Q: Answer the following question given this paragraph: You've probably noticed dew on the grass on a summer morning. Why does dew form? Remember that the land heats up and cools down fairly readily. So when night comes, the land cools. Air that was warm and humid in the daytime also cools over night. As the air cools, it can hold less water vapor. Some of the water vapor condenses on the cool surfaces, such as blades of grass. The temperature at which water vapor condenses is called the dew point . If this temperature is below freezing, ice crystals of frost form instead of dew ( Figure below ). The dew point occurs at 100 percent relative humidity. Can you explain why?. Q: What is the name of the "point" that refers to the temperature at which water vapor condenses? Choices: - melting point - brine point - water point - dew point A:
A: dew point

Answer the following question given this paragraph: Plants are somewhat limited by temperature in terms of where they can grow. They need temperatures above freezing while they are actively growing. They also need light, carbon dioxide, and water. These substances are required for photosynthesis. Like most other living things, plants need oxygen. Oxygen is required for cellular respiration. In addition, plants need minerals. The minerals are required to make proteins and other organic molecules. Q: Photosynthesis requires light, water and what else? Choices: - seasons - nitrogen - soil - carbon dioxide A:
**Answer**
carbon dioxide
