Q: Radon is inert and generally unreactive because it is which kind of gas? Read this paragraph and choose the correct option from the provided answers: Because radon is a noble gas, it is inert and generally unreactive. Despite this, exposure to even low concentrations of radon in air is quite dangerous. Describe the physical consequences of exposure to radon gas. Why are people who smoke more susceptible to these effects?. Choices: - ignoble gas - transitive gas - ideal gas - noble gas A:
noble gas

Q: What descend from clouds in funnel-like shapes that spin violently, producing powerful winds? Read this paragraph and choose the correct option from the provided answers: Figure 10.1 The mention of a tornado conjures up images of raw destructive power. Tornadoes blow houses away as if they were made of paper and have been known to pierce tree trunks with pieces of straw. They descend from clouds in funnel-like shapes that spin violently, particularly at the bottom where they are most narrow, producing winds as high as 500 km/h. (credit: Daphne Zaras, U. National Oceanic and Atmospheric Administration). Choices: - currents - rains - hurricanes - tornadoes A:
tornadoes

Q: What is likely to happen to a parasite if it kills its host? Read this paragraph and choose the correct option from the provided answers: Some parasites kill their host, but most do not. It's easy to see why. If a parasite kills its host, the parasite is also likely to die. Instead, parasites usually cause relatively minor damage to their host. Choices: - it thrives - it adapts - it mutates - it dies A:
it dies

Q: Chemical energy results from the particular arrangement of atoms in a chemical compound; the heat and light produced in this reaction are due to energy released during the breaking and reforming of what? Read this paragraph and choose the correct option from the provided answers: energy is released when particles in the nucleus of the atom are rearranged. (e) Chemical energy results from the particular arrangement of atoms in a chemical compound; the heat and light produced in this reaction are due to energy released during the breaking and reforming of chemical bonds. Electrical energy, nuclear energy, and chemical energy are different forms ofpotential energy (PE), which is energy stored in an object because of the relative positions or orientations of its components. A brick lying on the windowsill of a 10th-floor office has a great deal of potential energy, but until its position changes by falling, the energy is contained. In contrast, kinetic energy (KE) is energy due to the motionof an object. When the brick falls, its potential energy is transformed to kinetic energy, which is then transferred to the object on the ground that it strikes. Choices: - acid bonds - atom bonds - carbon bonds - chemical bonds A:
chemical bonds
