Answer the following question given this paragraph: As the example implies, gravitational force is completely negligible on a small scale, where the interactions of individual charged particles are important. On a large scale, such as between the Earth and a person, the reverse is true. Most objects are nearly electrically neutral, and so attractive and repulsive Coulomb forces nearly cancel. Gravitational force on a large scale dominates interactions between large objects because it is always attractive, while Coulomb forces tend to cancel. Q: Gravitational force on a large scale dominates interactions between large objects because it is always what? Choices: - ugly - vulnerable - suitable - attractive A:
attractive

Answer the following question given this paragraph: Autotrophs make their own food. Heterotrophs get food by eating other living things. Q: How do autotrophs get food? Choices: - From Water - Soak up from host cell - From Plant matter - make their own A:
make their own

Answer the following question given this paragraph: 41.4 Nitrogenous Wastes Ammonia is the waste produced by metabolism of nitrogen-containing compounds like proteins and nucleic acids. While aquatic animals can easily excrete ammonia into their watery surroundings, terrestrial animals have evolved special mechanisms to eliminate the toxic ammonia from their systems. Urea is the major byproduct of ammonia metabolism in vertebrate animals. Uric acid is the major byproduct of ammonia metabolism in birds, terrestrial arthropods, and reptiles. Q: When vertebrate animals metabolize ammonia what is the primary byproduct that is produced? Choices: - carbon monoxide - dioxide - proteins - urea A:
urea

Answer the following question given this paragraph: Increasing the temperature increases the average kinetic energy of the N2molecules. Q: Increasing the temperature of n2 molecules increases what energy of motion? Choices: - compression energy - residual energy - emotional energy - kinetic energy A:
kinetic energy
