Answer the following question given this paragraph: We use simple machines because they give us a mechanical advantage . Mechanical advantage is a measurement of the force amplification of a machine. In ideal machines, where there is no friction and the input work and output work are the same,. Q: What is is a measurement of the force amplification of a machine? Choices: - mechanical push - mechanical pull - force multiplier - mechanical advantage A:
mechanical advantage
Answer the following question given this paragraph: Q: What is only effective if ventilation is matched to blood flow through alveolar capillaries? Choices: - iron lung - blood pressur control - assisted breathing - breathing control A:
breathing control
Q: Answer the following question given this paragraph: stamens The part of the flower that produces pollen. Q: What is the part of the flower that produces pollen? Choices: - cones - stigma - leaves - stamen A:
A: stamen
Question: Answer the following question given this paragraph: Reflection is one of several ways that light can interact with matter. Light reflects off surfaces such as mirrors that do not transmit or absorb light. When light is reflected from a smooth surface, it may form an image. An image is a copy of an object that is formed by reflected (or refracted) light. Q: What is a copy of an object that is formed by reflected light? Choices: - deflection - instance - example - image A:
Answer: image

Answer the following question given this paragraph: The subfield of thermochemistry studies the energy changes that occur over the course of various chemical reactions. We will first look at how these changes are measured and then go into quantitative descriptions of heat transfer. Calorimetry is a term used to describe the measurement of heat transfers, usually by monitoring changes in the temperature of an isolated system. A calorimeter is a device used to measure temperature changes during chemical processes. The simplest type of calorimeter is the constant-pressure device illustrated in Figure below . Q: What is a device used to measure temperature changes during chemical processes called? Choices: - altimeter - alethiometer - thermometer - calorimeter A:
**Answer**
calorimeter
Q: Answer the following question given this paragraph: Biomes as different as deserts and wetlands share something very important. All biomes have populations of interacting species. Species interact in the same basic ways in all biomes. For example, all biomes have some species that prey on others for food. Q: Although they are as different as deserts and wetlands, all of these ecosystem units have populations of interacting species? Choices: - corals - continents - zoos - biomes A:
A: biomes
