Answer the following question given this paragraph: Temperature is the quantity measured by a thermometer. Temperature is related to the average kinetic energy of atoms and molecules in a system. Absolute zero is the temperature at which there is no molecular motion. There are three main temperature scales: Celsius, Fahrenheit, and Kelvin. Temperatures on one scale can be converted to temperatures on another scale using the following equations:. Q: What does a thermometer measure? Choices: - oxygen - precipitation - size - temperature A:
temperature
Answer the following question given this paragraph: During a massive eruption all of the material may be ejected from a magma changer. Without support, the mountain above the empty chamber may collapse. This produces a huge caldera . Calderas are generally round, bowl-shaped formations like the picture in Figure below . Q: After a massive eruption what will a mountain collapsing above an empty chamber create? Choices: - crater - cavern - valley - caldera A:
caldera

A: pancreas and liver
Question: Answer the following question given this paragraph: Air pollution causes acid rain, ozone depletion, and global warming. Q: What causes acid rain? Choices: - carbon dioxide - heavy pollution - chemicals in waterways - air pollution A:
Answer: air pollution

Answer the following question given this paragraph: Founder effect occurs when a few individuals start, or found, a new population. By chance, allele frequencies of the founders may be different from allele frequencies of the population they left. An example is described in the Figure below . Q: What effect occurs when a few individuals start, or found, a new population? Choices: - divergent - convergent - pioneer - founder A:
**Answer**
founder
Answer the following question given this paragraph: The Pressure of a Mixture of Gases: Dalton's Law Unless they chemically react with each other, the individual gases in a mixture of gases do not affect each other's pressure. Each individual gas in a mixture exerts the same pressure that it would exert if it present alone in the container (Figure 9.20). The pressure exerted by each individual gas in a mixture is called its partial pressure. This observation is summarized by Dalton's law of partial pressures: The total pressure of a mixture of ideal gases is equal to the sum of the partial pressures of the component gases: P Total = P A + P B + P C + . = i P i In the equation PTotal is the total pressure of a mixture of gases, PA is the partial pressure of gas A; PB is the partial pressure of gas B; PC is the partial pressure of gas C; and so on. Q: According to dalton's law, unless they chemically react with each other, individual gases in a mixture of gases do not affect each other's what? Choices: - mass - weight - density - pressure A:
pressure
