Answer the following question given this paragraph: Besides entertaining a cat, laser light has many other uses. It is used to scan bar codes, for example, and to carry communication signals in optical fibers. Optical fibers are extremely thin glass tubes that are used to guide laser light (see Figure below ). Sounds or pictures are encoded in pulses of laser light, which are then sent through an optical fiber. All of the light reflects off the inside of the fiber, so none of it escapes. As a result, the signal remains strong even over long distances. More than one signal can travel through an optic fiber at the same time, as you can see in Figure below . Optical fibers are used to carry telephone, cable TV, and Internet signals. Q: What do optical fibres look like? Choices: - square boxes - big flashlights - flat paper - thin glass tubes A:
(Answer)
thin glass tubes
Ques: Answer the following question given this paragraph: Why are algae considered plant-like? The main reason is that they contain chloroplasts and produce food through photosynthesis. However, they lack many other structures of true plants. For example, algae do not have roots, stems, or leaves. Some algae also differ from plants in being motile. They may move with pseudopods or flagella. Although not plants themselves, algae were probably the ancestors of plants. Q: Algae are similar to plants in that they both produce their food through what process? Choices: - mitosis - cell division - hydrolysis - photosynthesis A:
