Problem:OPTIONS:
- visible energy flow
- coolant energy flow
- spectral energy flow
- thermal energy flow

Answer the following question given this paragraph: A refrigerator must do work to reverse the normal direction of thermal energy flow. Work involves the use of force to move something, and doing work takes energy. In a refrigerator, the energy is usually provided by electricity. You can read in detail in the Figure below how a refrigerator does its work. For an animation of how a refrigerator works, go to this URL: http://www. chemistry. wustl. edu/~edudev/LabTutorials/CourseTutorials/LabTutorials/Thermochem/fridge_movie. html. Q: A refrigerator must do work to reverse the normal direction of what? A:
****
A: thermal energy flow

Answer the following question given this paragraph: Starches are complex carbohydrates. They are polymers of glucose. They consist of hundreds of glucose monomers bonded together. Plants make starch to store extra sugars. Consumers get starch from plants. Common sources of starch in the human diet are pictured in Figure below . Our digestive system breaks down starch to simple sugars, which our cells use for energy. Q: Our digestive system breaks down starch to what? A:
OPTIONS:
- Salts
- Waste
- pattern sugars
- simple sugars
simple sugars

Answer the following question given this paragraph: Barrier islands provide natural protection to shorelines. Storm waves strike the barrier island before they reach the shore. People also build artificial barriers, called breakwaters . Breakwaters also protect the shoreline from incoming waves. You can see an example of a breakwater in Figure below . It runs parallel to the coast like a barrier island. Q: What kind of islands provide natural protection to shorelines? A:
OPTIONS:
- patch islands
- locational islands
- edge islands
- barrier islands

Answer: barrier islands

Question: Answer the following question given this paragraph: There are only about 6200 known species of amphibians. They are placed in three orders: frogs, salamanders, and caecilians. Table below shows a picture of an amphibian in each order. It also provides additional information about the orders. Q: What are the 3 orders of amphibians? A:
OPTIONS:
- bees, caddisflies, antilions
- monotremata, artiodactyla, rodentia
- hagfish, lampreys, acanthodii
- frogs, salamanders, caecilians
Answer: frogs, salamanders, caecilians
