Answer the following question given this paragraph: Kinetic energy is the energy of anything in motion. Your muscles move your leg, your foot kicks the ball, and the ball gains kinetic energy ( Figure below ). The kinetic energy was converted from potential energy that was in your leg before the kick. The action of kicking the ball is energy changing forms. The same is true for anything that involves change. Q: Which type of energy is the energy of anything in motion? Choices: - residual engergy - diffuse energy - physiological engergy - kinetic engergy A:
kinetic engergy

Answer the following question given this paragraph: Scientists are searching for ways to create controlled nuclear fusion reactions in order to produce safe nuclear power. Fusion involves only harmless, plentiful elements but requires extremely high temperatures. Q: What type of diseases in humans are caused by protozoa? Choices: - protozoa diseases - dysentery - diarrhea - protist diseases A:
protist diseases

Answer the following question given this paragraph: Saprotrophs are the final step in decomposition. They feed on any remaining organic matter that is left after other decomposers do their work. Saprotrophs include fungi and single-celled protozoa. Fungi are the only organisms that can decompose wood. Q: What are the only organisms that can decompose wood? Choices: - bacteria - protists - fossil - fungi A:
fungi
