Ques: Answer the following question given this paragraph: Hemoglobin is the iron-containing oxygen-transport protein in the red blood cells of all vertebrates. The hemoglobin molecule is an assembly of four globular protein subunits, each tightly associated with a non-protein heme group. The heme group binds to the iron ion. The most common hemoglobin is hemoglobin A, a tetramer consisting of two alpha and two beta subunits, denoted as 22. Q: What is the name of the iron-containing oxygen-transport protein in the red blood cells of all vertebrates? Choices: - plasma - platelet - ferric acid - hemoglobin A:
Ans: hemoglobin

Ques: Answer the following question given this paragraph: Less dramatic types of mass wasting move Earth materials slowly down a hillside. Slump is the sudden movement of large blocks of rock and soil down a slope. ( Figure below ). All the material moves together in big chunks. Slumps may happen when a layer of slippery, wet clay is underneath the rock and soil on a hillside. Or they may occur when a river (or road) undercuts a slope. Slump leaves behind crescent-shaped scars on the hillside. Q: What is the term for the sudden movement of large blocks of rock and soil down a slope? Choices: - sludge - torrent - hurricane - slump A:
Ans: slump

Ques: Answer the following question given this paragraph: In this equation, two substances combine to make a single substance. This is a composition reaction. Two different substances react to make two new substances. This does not fit the definition of either a composition reaction or a decomposition reaction, so it is neither. In fact, you may recognize this as a double-replacement reaction. A single substance reacts to make multiple substances. This is a decomposition reaction. Q: What type of reaction causes two substances to combine to make a single substance? Choices: - component reaction - spontaneous mutation - metabolism - composition reaction A:
Ans: composition reaction

Ques: Answer the following question given this paragraph: Figure 16.17 The body contains three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle. Notice that skeletal muscle cells are long and cylindrical, they have multiple nuclei, and the small, dark nuclei are pushed to the periphery of the cell. Smooth muscle cells are short, tapered at each end, and have only one nucleus each. Cardiac muscle cells are also cylindrical, but short. The cytoplasm may branch, and they have one or two nuclei in the center of the cell. (credit: modification of work by NCI, NIH; scale-bar data from Matt Russell). Q: Name the three types of muscle tissue. Choices: - cardiac, smooth, long - smooth, long, tight - skeletal, cardiac, long - skeletal, smooth, cardiac A:
Ans:
skeletal, smooth, cardiac
