Question: Answer the following question given this paragraph: Density is an expression of the mass of substance in terms of the volume occupied by the substance. Q: What expresses the mass of substance in terms of the volume occupied by the substance? A:
OPTIONS:
- velocity
- frequency
- diameter
- density
Answer: density

input with options: Answer the following question given this paragraph: When light is refracted its wavelength and speed change; however, its frequency remains the same as the frequency of the light source. Proof of this is that light retains its original color under water. For example, blue light is still blue under water. Q: Light retains its original color under water because what remains the same when light is refracted? A:
OPTIONS:
- wave length
- density
- sound
- frequency
output: frequency

Q: Answer the following question given this paragraph: Nuclear energy is produced by splitting the nucleus of an atom. This releases a huge amount of energy. Q: Splitting the nucleus of an atom produces a massive amount of what type of energy? A:

OPTIONS:
- likely energy
- radioactive energy
- sure energy
- nuclear energy

A: nuclear energy

input: OPTIONS:
- mechanical energy
- used energy
- stored energy
- internal energy Now, answer this question: Answer the following question given this paragraph: Internal energythe sum of the kinetic and potential energies of a system's atoms and molecules. Can be divided into many subcategories, such as thermal and chemical energy. Depends only on the state of a system (such as its P , V , and T ), not on how the energy entered the system. Change in internal energy is path independent. Q: The sum of the kinetic and potential energies of a system's atoms and molecules is called what? A:
A:
output: internal energy

Answer the following question given this paragraph: Sponges are characterized by a feeding system unique among animals. As sponges don't have mouths, they must feed by some other method. Sponges have tiny pores in their outer walls through which water is drawn. Cells in the sponge walls filter food from the water as the water is pumped through the body and out other larger openings. The flow of water through the sponge is unidirectional, driven by the beating of flagella, which line the surface of chambers connected by a series of canals. Q: The flow of water through the sponge is unidirectional, driven by the beating of what? A:

OPTIONS:
- antennae
- cilia
- fin
- flagella

Answer: flagella
