Answer the following question given this paragraph: The law of conservation of energy states that matter cannot be created or destroyed. Whether a chemical reaction absorbs or releases energy, there is no overall change in the amount of energy during the reaction. Q: What law states that matter cannot be created or destroyed? Choices: - Murphy's Law - law of inertia - construct of energy - conservation of energy A:
**Answer**
conservation of energy

Answer the following question given this paragraph: There are about 27,000 species of bony fish ( Figure below ), which are divided into two classes: ray-finned fish and lobe-finned fish. Most bony fish are ray-finned. These thin fins consist of webs of skin over flexible spines. Lobe-finned fish, on the other hand, have fins that resemble stump-like appendages. Q: What is the second class of fish after ray-finned fish? Choices: - pine - finned fish - spar - finned fish - star-finned fish - lobe-finned fish A:
**Answer**
lobe-finned fish

Answer the following question given this paragraph: Green light has a higher frequency than microwaves. It is possible to calculate it, but since the speed of an electromagnetic wave is constant we know that waves with higher wavelengths must have a lower frequency based on the wave equation. Q: What of a electromagnetic wave can be calculated using the wave equation due to their speed always being constant? Choices: - oscillation - resonance - sound - frequency A:
**Answer**
frequency
