Q: Stoichiometric coefficients are used in chemical equations to indicate the amounts of reactants and what? Choices: - imports - fuels - consumers - products A:

Answer the following question given this paragraph: Childhood cancer is rare. The main type of cancer in children is leukemia. It makes up about one third of all childhood cancers. It occurs when the body makes abnormal white blood cells. Q: What is the most common type of cancer developed in children? Choices: - anemia - lung cancer - stomach cancer - leukemia A:
leukemia
Q: Answer the following question given this paragraph: The law of conservation of energy states that matter cannot be created or destroyed. Whether a chemical reaction absorbs or releases energy, there is no overall change in the amount of energy during the reaction. Q: What law states that matter cannot be created or destroyed? Choices: - Murphy's Law - law of inertia - construct of energy - conservation of energy A:
A: conservation of energy
Question: Answer the following question given this paragraph: Static friction acts on objects when they are resting on a surface. For example, if you are hiking in the woods, there is static friction between your shoes and the trail each time you put down your foot (see Figure below ). Without this static friction, your feet would slip out from under you, making it difficult to walk. In fact, that's exactly what happens if you try to walk on ice. That's because ice is very slippery and offers very little friction. Q: Static friction acts on objects when they are resting on what? Choices: - a single point - their laurels - a pool of water - a surface A:
Answer: a surface

Answer the following question given this paragraph: Movable joints allow the greatest movement and are the most common. In these joints, the bones are connected by ligaments. The surfaces of the bones at the joints are covered with a smooth layer of cartilage. It reduces friction between the bones when they move. The space between the bones is also filled with a liquid called synovial fluid. It helps to cushion the bones. There are several different types of movable joints. You can see three of them in Figure below . Move these three joints in your own skeleton to experience the range of motion each allows. Q: The surfaces of the bones at the joints are covered with a smooth layer of cartilage, which reduces what force between the bones when they move? Choices: - vibration - expulsion - gravity - friction A:
**Answer**
friction
Q: Answer the following question given this paragraph: When you are cold, what does your body do to keep warm? You shiver to warm up your body. When you are too warm, you sweat to release heat. When any living organism gets thrown off balance, its body or cells help it return to normal. In other words, living organisms have the ability to keep a stable internal environment. Maintaining a balance inside the body or cells of organisms is known as homeostasis . Like us, many animals have evolved behaviors that control their internal temperature. A lizard may stretch out on a sunny rock to increase its internal temperature, and a bird may fluff its feathers to stay warm ( Figure below ). Q: Maintaining a balance inside the body or cells of organisms is known as? Choices: - ketosis - equanimity - consciousness - homeostasis A:
A: homeostasis
