Q: Answer the following question given this paragraph: Matter can be identified as an element, a compound, or a mixture. Q: What can be identified as an element, a compound, or a mixture? Choices: - waves - energy - light - matter A:
A: matter

Q: Answer the following question given this paragraph: Generators may be set up to produce either direct or alternating current. Generators in cars and most power plants produce alternating current. Regardless of the type of current, all generators change kinetic energy to electrical energy. Q: When using a generator, we are transforming what energy into what energy? Choices: - magnetic into kinetic - thermal into radioactive - mechanical into thermal - kinetic into electrical A:
A: kinetic into electrical

Q: Answer the following question given this paragraph: During sexual reproduction, two parents are involved. Most animals are dioecious , meaning there is a separate male and female sex, with the male producing sperm and the female producing eggs. When a sperm and egg meet during fertilization , a zygote , the first cell of a new organism, is formed ( Figure below ). This process combines the genetic material from both parents. The resulting organism will be genetically unique. The zygote will divide by mitosis and grow into the embryo. Q: In dioecious animals, females generally produce what contribution to reproduction? Choices: - milk - warmth - intelligence - eggs A:
A: eggs

Q: Answer the following question given this paragraph: Some regions of the electron cloud are denser than others. The denser regions are areas where electrons are most likely to be. These regions are called orbitals . Each orbital has a maximum of just two electrons. Different energy levels in the cloud have different numbers of orbitals. Therefore, different energy levels have different maximum numbers of electrons. Table below lists the number of orbitals and electrons for the first four energy levels. Energy levels farther from the nucleus have more orbitals. Therefore, these levels can hold more electrons. Q: The denser regions of the electron cloud are called what? Choices: - cores - lattices - isotopes - orbitals A:
A: orbitals
