Q: Answer the following question given this paragraph: The temperature of a region is the other important part of climate. The rate of chemical reactions increases with higher temperatures. The rate doubles for every 10C increase in temperature. Plants and bacteria grow and multiply faster in warmer areas. Q: What happens to the rate of chemical reactions in higher temperatures? A:

OPTIONS:
- they become erratic
- they stop
- they decrease
- they increase

A: they increase

input: OPTIONS:
- velocity
- density
- duration
- intensity Now, answer this question: Answer the following question given this paragraph: The energy of sound waves spreads out over a greater area as the waves travel farther from the sound source. This diagram represents just a small section of the total area of sound waves spreading out from the source. Sound waves actually travel away from the source in all directions. As distance from the source increases, the area covered by the sound waves increases, lessening their intensity. Q: As distance from the source increases, the area covered by the sound waves increases, lessening what? A:
A:
output: intensity

Answer the following question given this paragraph: All ecosystems need a constant input of energy in the form of sunlight or chemical compounds. Living things can be classified based on how they obtain energy as producers, consumers, or decomposers. Q: The energy for an ecosystem can come from sunlight or _________? A:

OPTIONS:
- radiation compounds
- fossil fuels
- rain
- chemical compounds

Answer: chemical compounds

Problem: OPTIONS:
- a induce impulse
- a metabolism impulse
- nerve reaction
- a nerve impulse
Q: Answer the following question given this paragraph: A nerve impulse begins when a neuron receives a chemical stimulus. The impulse travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that carry the nerve impulse to the next cell. Q: What begins when a neuron receives a chemical stimulus? A:
Answer: a nerve impulse

Problem:OPTIONS:
- hybrid electricity
- aqua-electricity
- photovoltaic cells
- photoelectrolysis

Answer the following question given this paragraph: With fossil fuels becoming more expensive and less available, scientists are looking for other energy sources. Hydrogen has long been considered an ideal source, since it does not pollute when it burns. The problem has been finding ways to generate hydrogen economically. One new approach that is being studied is photoelectrolysis the generation of electricity using photovoltaic cells to split water molecules. This technique is still in the research stage, but appears to be a very promising source of power in the future. Q: What is the generation of electricity using photovoltaic cells to split water molecules called? A:
****
A: photoelectrolysis

Problem:OPTIONS:
- circuit
- dial
- arc
- loop

Answer the following question given this paragraph: Meters, such as those in analog fuel gauges on a car, are another common application of magnetic torque on a current-carrying loop. Figure 22.37 shows that a meter is very similar in construction to a motor. The meter in the figure has its magnets shaped to limit the effect of by making B perpendicular to the loop over a large angular range. Thus the torque is proportional to I and not. Q: Meters, such as those in analog fuel gauges on a car, are a common application of magnetic torque on a current-carrying what? A:
****
A:
loop
