Answer the following question given this paragraph: Weather is always changing. One day might be cold and cloudy. The next day might be warm and sunny. Even on the same day, the weather can change a lot. A beautiful morning might be followed by a stormy afternoon. Why does weather change? The main reason is moving air masses. Q: What is the main reason for weather change? Choices: - climate change - moving energy masses - seasons - moving air masses A:
moving air masses
Answer the following question given this paragraph: The combined gas law relates pressure, volume, and temperature of a gas. Q: Which law relates the pressure, volume, and temperature of a gas? Choices: - directions gas law - shifts gas law - newton's law - combines gas law A:
combines gas law
Q: Answer the following question given this paragraph: The theory of climate change is very new. In fact, scientists don't even call it a theory. But it meets the requirements. These are the things we know: (1) average global temperatures are rising, (2) greenhouse gases trap heat in the atmosphere, (3) CO 2 is released into the atmosphere when fossil fuels are burned, (4) CO 2 is a greenhouse gas, (5) more CO 2 in the atmosphere traps more heat so global temperature is rising. No information contradicts this theory, although some details have not been worked out. The theory is very effective at predicting future events, which are already taking place. This idea will be explored in detail in the chapter Atmospheric Processes . Q: Which theory helps predict future events in weather? Choices: - expected change theory - future weather theory - carbon change theory - climate change theory A:
A: climate change theory
Question: Answer the following question given this paragraph: Electric generators convert mechanical energy to electric energy. The generator consists of some number of wire loops wrapped around an iron core and placed in a strong magnetic field. The loops of wire and the iron core are called the armature . The armature is mounted so that it can rotate freely inside the magnetic field. Mechanical energy is used to spin the armature in the field so that the wire loops cut across the field and produce electric current. The of this current is calculated by . Q: Electric generators convert what type of energy to electric energy? Choices: - electromagnetic energy - thermodynamic energy - fluid energy - mechanical energy A:
Answer: mechanical energy

Answer the following question given this paragraph: Neurons are classified based on the direction in which they carry nerve impulses. Q: Neurons are classified based on the direction in which they carry what? Choices: - metabolism impulses - energy - neurotransmitters - nerve impulses A:
**Answer**
nerve impulses
Q: Answer the following question given this paragraph: Strong acids completely transfer their acidic protons to the solvent when dissolved in water. When a weak acid is dissolved in water, most of the molecules will retain their acidic protons, and only a small percentage will dissociate. Q: When dissolved in water, what do strong acids transfer to the solvent completely? Choices: - acidic neutrons - acidic electrons - acidic proteins - acidic protons A:
A: acidic protons
