Answer the following question given this paragraph: Most waves approach the shore at an angle. The part of the wave that is nearer the shore reaches shallow water sooner than the part that is farther out. The shallow part of the wave "feels" the bottom first. This slows down the inshore part of the wave and makes the wave "bend. " This bending is called refraction . Q: What three characteristics do waves have? A:
****
A: reflection, refraction and deflection

Answer the following question given this paragraph: Protein Structure. Primary protein structure is the sequence of amino acids in a single polypeptide. Secondary protein structure refers to internal shapes, such as alpha helices and beta pleated sheets, that a single polypeptide takes on due to bonds between atoms in different parts of the polypeptide. Tertiary protein structure is the overall three-dimensional shape of a protein consisting of one polypeptide. Quaternary protein structure is the shape of a protein consisting of two or more polypeptides. For a brief animation of protein structure, see www. stolaf. edu/people/giannini/flashanimat/proteins/protein%20structure. swf . Q: A sequence of amino acids in single polypeptide is the primary structure for what? A:
OPTIONS:
- lipids
- cells
- dna
- proteins
proteins

Answer the following question given this paragraph: In the winter, the temperature often gets well below the freezing point of water. This condition can create problem in car radiators. If the water freezes, water hoses will break, the engine block can crack, and significant damage can be done to the car. Q: In winter, water does what, becoming solid and causing hoses to rupture and engine blocks to crack? A:
OPTIONS:
- crystallizes
- shrinks
- fractures
- freeze

Answer: freeze

Question: Answer the following question given this paragraph: Further away from the heart, the aorta branches into smaller arteries, which eventually branch into capillaries. Capillaries are the smallest type of blood vessel; they connect very small arteries and veins. Gases and other substances are exchanged between cells and the blood across the very thin walls of capillaries. Q: What are the smallest type of blood vessel? A:
OPTIONS:
- varicose veins
- spider veins
- arteries
- capillaries
Answer: capillaries
