Q: What type of gas is used to fill glass tubes of lighted signs? Read this paragraph and choose the correct option from the provided answers: Noble gases are also used to fill the glass tubes of lighted signs like the one in the Figure below . Although noble gases are chemically nonreactive, their electrons can be energized by sending an electric current through them. When this happens, the electrons jump to a higher energy level. When the electrons return to their original energy level, they give off energy as light. Different noble gases give off light of different colors. Neon gives off reddish-orange light, like the word "Open" in the sign below. Krypton gives off violet light and xenon gives off blue light. Choices: - synthetic - inert - natural - noble A:
noble

Q: What do all respiratory diseases affect? Read this paragraph and choose the correct option from the provided answers: Reproduction Fungi reproduce sexually and/or asexually. Perfect fungi reproduce both sexually and asexually, while the so-called imperfect fungi reproduce only asexually (by mitosis). In both sexual and asexual reproduction, fungi produce spores that disperse from the parent organism by either floating on the wind or hitching a ride on an animal. Fungal spores are smaller and lighter than plant seeds. The giant puffball mushroom bursts open and releases trillions of spores. The huge number of spores released increases the likelihood of landing in an environment that will support growth (Figure 24.6). Choices: - liquid exchange process - helium exchange process - transit exchange process - gas exchange process A:
gas exchange process
