Answer the following question given this paragraph: Ice caps are large glaciers that cover a larger area than just a valley. An ice cap can bury an entire mountain range or region ( Figure below ). Glaciers come off of ice caps into valleys. Q: What are large glaciers that cover a larger area than just a valley? Choices: - icebergs - glacial continents - ice floes - ice caps A:
ice caps
Answer the following question given this paragraph: Ambrosia beetles live in the bark of trees. Like ants and termites, they grow fungi inside the bark of trees and use it to help digest their food. Q: Like ants and termites, they grow fungi inside the bark of trees and use it to help do what? Choices: - clean the nest - kill prey - weaken enemies - digest food A:
digest food
Q: Answer the following question given this paragraph: A battery is an electrochemical cell or series of cells that produces an electric current. In principle, any galvanic cell could be used as a battery. An ideal battery would never run down, produce an unchanging voltage, and be capable of withstanding environmental extremes of heat and humidity. Real batteries strike a balance between ideal characteristics and practical limitations. For example, the mass of a car battery is about 18 kg or about 1% of the mass of an average car or light-duty truck. This type of battery would supply nearly unlimited energy if used in a smartphone, but would be rejected for this application because of its mass. Thus, no single battery is "best" and batteries are selected for a particular application, keeping things like the mass of the battery, its cost, reliability, and current capacity in mind. There are two basic types of batteries: primary and secondary. A few batteries of each type are described next. Q: What device is an electrochemical cell or series of cells that produces an electric current? Choices: - reactor - magnet - generator - battery A:
A: battery
Question: Answer the following question given this paragraph: 47.2 The Importance of Biodiversity to Human Life Humans use many compounds that were first discovered or derived from living organisms as medicines: secondary plant compounds, animal toxins, and antibiotics produced by bacteria and fungi. More medicines are expected to be discovered in nature. Loss of biodiversity will impact the number of pharmaceuticals available to humans. Crop diversity is a requirement for food security, and it is being lost. The loss of wild relatives to crops also threatens breeders' abilities to create new varieties. Ecosystems provide ecosystem services that support human agriculture: pollination, nutrient cycling, pest control, and soil development and maintenance. Loss of biodiversity threatens these ecosystem services and risks making food production more expensive or impossible. Wild food sources are mainly aquatic, but few are being managed for sustainability. Fisheries' ability to provide protein to human populations is threatened when extinction occurs. Biodiversity may provide important psychological benefits to humans. Additionally, there are moral arguments for the maintenance of biodiversity. Q: Humans use many compounds that were first discovered or derived from living organisms as medicines: secondary plant compounds, animal toxins, and antibiotics produced by these? Choices: - bacteria and tumors - molecules and fungi - tumors and fungi - bacteria and fungi A:
Answer: bacteria and fungi

Answer the following question given this paragraph: Many thermometers measure temperature with a liquid that expands when it gets warmer and contracts when it gets cooler. Look at the common household thermometer pictured in the Figure below . The red liquid rises or falls in the glass tube as the temperature changes. Temperature is read off the scale at the height of the liquid in the tube. To learn more about measuring temperature, watch the animation "Measuring Temperature" at this URL: http://www. sciencehelpdesk. com/unit/science2/3. Q: How does the liquid in a thermometer respond to heat or cold? Choices: - freezes or boils - disappears - rises or vaporizes - expands or contracts A:
**Answer**
expands or contracts

Answer the following question given this paragraph: When charged particles accelerate , changing electric and magnetic fields radiate outward. The traveling electric and magnetic fields of an accelerating (often oscillating) charged particle are known as electromagnetic radiation or light. Q: Changing electric and mnagnetic fields radiate outward when? Choices: - particles lose their charge - particles multiply - firing particles accelerate - charged particles accelerate A:
**Answer**
charged particles accelerate
