Question: Q: Goldfish, tuna, salmon, perch, and cod are examples of which group of fish? Read this paragraph and choose the correct option from the provided answers: Ray-finned fish include the majority of living fish species. including goldfish, tuna, salmon, perch, and cod. They have a bony endoskeleton and a swim bladder. Their thin fins consist of webs of skin over flexible bony rays, or spines. The fins lack muscle, so their movements are controlled by muscles in the body wall. You can compare their ray fins with the fleshy fins of lobe-finned fish in Figure below . Choices: - spiny-lobed fish - cartilaginous fish - bony fish - ray-finned fish A:
Answer: ray-finned fish

Question: Q: What part of an atom is electrically neutral? Read this paragraph and choose the correct option from the provided answers: An atom's protons and electrons carry electrical charges. Protons, with their positive charge, are designated p+. Electrons, which have a negative charge, are designated e. An atom's neutrons have no charge: they are electrically neutral. Just as a magnet sticks to a steel refrigerator because their opposite charges attract, the positively charged protons attract the negatively charged electrons. This mutual attraction gives the atom some structural stability. The attraction by the positively charged nucleus helps keep electrons from straying far. The number of protons and electrons within a neutral atom are equal, thus, the atom's overall charge is balanced. Choices: - protons - electrons - newtons - neutrons A:
Answer: neutrons

Question: Q: What is the name for a matter that has a fixed volume and a fixed shape? Read this paragraph and choose the correct option from the provided answers: Ice is an example of solid matter. A solid is matter that has a fixed volume and a fixed shape. Figure below shows examples of matter that are usually solids under Earth conditions. In the figure, salt and cellulose are examples of crystalline solids. The particles of crystalline solids are arranged in a regular repeating pattern. The steaks and candle wax are examples of amorphous ("shapeless") solids. Their particles have no definite pattern. Choices: - gas - stable - liquid - solid A:
Answer:
solid
