Answer the following question given this paragraph: Figure 20.4 Current I is the rate at which charge moves through an area A , such as the cross-section of a wire. Conventional current is defined to move in the direction of the electric field. (a) Positive charges move in the direction of the electric field and the same direction as conventional current. (b) Negative charges move in the direction opposite to the electric field. Conventional current is in the direction opposite to the movement of negative charge. The flow of electrons is sometimes referred to as electronic flow. Q: Positive charges move in the direction of the electric field and the same direction as what current? Choices: - alternating current - direct current - relativity current - conventional current A:
conventional current
Q: Answer the following question given this paragraph: Secondary pollutants are formed when primary pollutants interact with sunlight, air, or each other. They do not directly cause pollution. However, when they interact with other parts of the air, they do cause pollution. For example, ozone is created when some pollutants interact with sunlight. High levels of ozone in the atmosphere can cause problems for humans. Q: What are formed when primary pollutants interact with sunlight, air, or each other? Choices: - cross pollutants - typical pollutants - secondary contaminants - secondary pollutants A:
A: secondary pollutants
Question: Answer the following question given this paragraph: Deposition as a change of state often occurs in nature. For example, when warm moist air comes into contact with very cold surfacessuch as the ground or objects on the groundice crystals are deposited on them. These ice crystals are commonly called frost. Look at the dead leaf and blades of grass in the Figure below . They are covered with frost. If you look closely, you can see the individual crystals of ice. You can watch a demonstration of frost forming on the side of a very cold can at the URL below. (Click on the mulitmedia choice "Ice on a Can. "). The ice in the can has been cooled to a very low temperature by adding salt to it. If you want to do the demonstration yourself, follow the procedure at the URL. http://www. middleschoolchemistry. com/lessonplans/chapter2/lesson4. Q: What are the ice crystals that form on the ground called? Choices: - snow - granules - sleet - frost A:
Answer: frost

Answer the following question given this paragraph: Arthropods range in length from about 1 millimeter (0.04 inches) to 4 meters (about 13 feet). They have a segmented body with a hard exoskeleton. They also have jointed appendages. The body segments are the head, thorax, and abdomen (see Figure below ). In some arthropods, the head and thorax are joined together as a cephalothorax. Q: The head, thorax, and abdomen comprise what type of body structure, possessed by arthropods? Choices: - vertebrate - elongated - permeable - segmented A:
**Answer**
segmented

Answer the following question given this paragraph: The density of air varies from place to place. Air density depends on several factors. One is temperature. Like other materials, warm air is less dense than cool air. Since warmer molecules have more energy, they are more active. The molecules bounce off each other and spread apart. Another factor that affects the density of air is altitude. Q: Since warmer molecules have more energy, they are more what? Choices: - inactive - dense - abundant - active A:
(Answer)
active
