Answer the following question given this paragraph: The major component of a solution is called the solvent. The minor component of a solution is called the solute. By major and minor we mean whichever component has the greater presence by mass or by moles. Sometimes this becomes confusing, especially with substances with very different molar masses. However, here we will confine the discussion to solutions for which the major component and the minor component are obvious. Solutions exist for every possible phase of the solute and the solvent. Salt water, for example, is a solution of solid NaCl in liquid water; soda water is a solution of gaseous CO2 in liquid water, while air is a solution of a gaseous solute (O2) in a gaseous solvent (N2). In all cases, however, the overall phase of the solution is the same phase as the solvent. Q: The major component of a solution is called what? Choices: - solute - mixture - water - solvent A:
solvent
Answer the following question given this paragraph: Breakwaters are structures that protect the coast like barrier islands. Groins are structures that help prevent longshore drift from eroding a beach. Q: What are structures that protect the coast like barrier islands called? Choices: - domes - dunes - fortresses - breakwaters A:
breakwaters
Q: Answer the following question given this paragraph: Various conditions affect enzyme function. Pepsin and trypsin are two digestive enzymes that work in contrasting environments. Q: Pepsin and trypsin are examples of enzymes involved in what bodily process? Choices: - filtration - regeneration - perspiration - digestion A:
A: digestion
Question: Answer the following question given this paragraph: Living chordates are mainly vertebrates. In vertebrates, the notochord develops into a backbone, or vertebral column, after the embryonic stage. A small percentage of chordates are invertebrates. Their notochord never develops into a backbone. Invertebrate chordates include tunicates and lancelets. Both groups of animals are small and relatively primitive. They are probably similar to the earliest chordates that evolved more than 500 million years ago. Q: During the embryonic stage of vertebrates, the notochord develops into what? Choices: - rib cage - umbilical cord - brain stem - backbone A:
Answer: backbone

Answer the following question given this paragraph: Terrestrial biomes are determined mainly by temperature and moisture. Plants are the primary producers. Examples of terrestrial biomes include tropical rainforests, temperate grasslands, and tundra. Q: What are terrestrial biomes determined by? Choices: - moisture and elevation - pressure and temperature - time and temperature - temperature and moisture A:
temperature and moisture
