Problem:OPTIONS:
- efficient composition
- unique composition
- complex composition
- variable composition

Answer the following question given this paragraph: When two or more pure substances are combined together, a mixture is formed. Unlike pure substances, mixtures have a variable composition. Variable composition indicates that the relative proportions of the mixtures components may vary, and they can be separated by physical methods. There are two main types of mixtures. Q: Unlike pure substances, mixtures have a what? A:
****
A: variable composition

Answer the following question given this paragraph: Summary Subatomic particles of the nucleus (protons and neutrons) are called nucleons. Anuclide is an atom with a particular number of protons and neutrons. An unstable nucleus that decays spontaneously is radioactive, and its emissions are collectively called radioactivity. Isotopes that emit radiation are Saylor URL: http://www. saylor. org/books. Q: What are the subatomic particles of the nucleus called? A:
OPTIONS:
- cores
- eukaryotes
- protons
- nucleons
nucleons

Answer the following question given this paragraph: Summary The concentration of a species in solution can be determined by quantitative analysis. One such method is a titration, in which a measured volume of a solution of one substance, the titrant, is added to a solution of another substance to determine its concentration. The equivalence point in a titration is the point at which exactly enough reactant has been added for the reaction to go to completion. A standard solution, a solution whose concentration is known precisely, is used to determine the concentration of the titrant. Many titrations, especially those that involve acidbase reactions, rely on an indicator. The point at which a color change is observed is the endpoint, which is close to the equivalence point if the indicator is chosen properly. Q: What helps determine the concentration of a species in a solution? A:
OPTIONS:
- technical analysis
- qualitative analysis
- fundamental analysis
- quantitative analysis

Answer: quantitative analysis

Question: Answer the following question given this paragraph: Figure 26.13 These flowers grow in a botanical garden border in Bellevue, WA. Flowering plants dominate terrestrial landscapes. The vivid colors of flowers are an adaptation to pollination by animals such as insects and birds. (credit: Myriam Feldman). Q: The vivid colors of flowers are an adaptation designed to encourage what by animals such as insects and birds? A:
OPTIONS:
- eating
- consumption
- flowering
- pollination
Answer: pollination

input: OPTIONS:
- blowing friction
- opposing friction
- surface friction
- rolling friction Now, answer this question: Answer the following question given this paragraph: Rolling friction is friction that acts on objects when they are rolling over a surface. Rolling friction is much weaker than sliding friction or static friction. This explains why most forms of ground transportation use wheels, including bicycles, cars, 4-wheelers, roller skates, scooters, and skateboards. Ball bearings are another use of rolling friction. You can see what they look like in the Figure below . They let parts of a wheel or other machine roll rather than slide over on another. Q: What is friction that acts on objects while it is rolling over a surface called? A:
A:
output:
rolling friction
