Answer the following question given this paragraph: Fractures are breaks in bone, usually caused by excessive stress on bone. Fractures heal when osteoblasts form new bone. The animation at this link shows how this happens: http://www. youtube. com/watch?v=qVougiCEgH8 . Soon after a fracture, the body begins to repair the break. The area becomes swollen and sore. Within a few days, bone cells travel to the break site and begin to rebuild the bone. It takes about two to three months before compact and spongy bone form at the break site. Sometimes the body needs extra help in repairing a broken bone. In such a case, a surgeon will piece a broken bone together with metal pins. Moving the broken pieces together will help keep the bone from moving and give the body a chance to repair the break. Q: What is it called when breaks in bone occur that is usually caused by excessive stress on the bone? A:

OPTIONS:
- fragments
- faults
- ruptures
- fractures

Answer: fractures

Problem: OPTIONS:
- oxygen
- helium
- hydrogen
- lipids
Q: Answer the following question given this paragraph: Lipids provide the body with energy and serve other vital functions. One gram of lipids provides 9 Calories of energy. You need to eat small amounts of lipids for good health. However, large amounts can be harmful, especially if they contain saturated fatty acids from animal foods. Q: What essential molecules can be harmful if ingested in large amounts, especially if they contain saturated fatty acids from animal foods? A:
Answer: lipids

Problem:OPTIONS:
- fuel
- hydrogen
- power
- energy

Answer the following question given this paragraph: Maintaining a high metabolic rate takes a lot of energy. The energy must come from food. Therefore, mammals need a nutritious and plentiful diet. The diets of mammals are diverse. Except for leaf litter and wood, almost any kind of organic matter may be eaten by mammals. Some mammals are strictly herbivores or strictly carnivores. However, most mammals will eat other foods if necessary. Some mammals are omnivores. They routinely eat a variety of both plant and animal foods. Most mammals also feed on a variety of other species. The few exceptions include koalas, which feed only on eucalyptus plants, and giant pandas, which feed only on bamboo. Types of mammalian diets and examples of mammals that eat them are given in Table below . How would you classify your own diet?. Q: Maintaining a high metabolic rate takes a lot of what? A:
****
A: energy

Answer the following question given this paragraph: The cell wall is a rigid layer that surrounds the cell membrane of a plant cell. It's made mainly of the complex carbohydrate called cellulose. The cell wall supports and protects the cell. The cell wall isn't solid like a brick wall. It has tiny holes in it called pores. The pores let water, nutrients, and other substances move into and out of the cell. Q: What rigid layer surrounds the cell membrane of a plant cell? A:
OPTIONS:
- bark
- epidermis
- cuticle
- cell wall
cell wall

Answer the following question given this paragraph: Hydrates Many ionic compounds occur as hydrates, compounds that contain specific ratios of loosely bound water molecules, called waters of hydration. Waters of hydration can often be removed simply by heating. For example, calcium dihydrogen phosphate can form a solid that contains one molecule of water per Ca(H2PO4)2 unit and is used as a leavening agent in the food industry to cause baked goods to rise. The empirical formula for the solid is Ca(H 2PO4)2H2O. In contrast, copper sulfate usually forms a blue solid that contains five waters of hydration per formula unit, with the empirical formula CuSO 45H2O. When heated, all five water molecules are lost, giving a white solid with the empirical formula CuSO 4 (Figure 2.9 "Loss of Water from a Hydrate with Heating"). Q: Many ionic compounds occur as hydrates, compounds that contain specific ratios of loosely bound water molecules, called waters of hydration. waters of hydration can often be removed simply by doing this? A:
OPTIONS:
- cooling
- observing
- melting
- heating

Answer:
heating
