Answer the following question given this paragraph: Protists do not create food sources only for sea-dwelling organisms. For instance, certain anaerobic parabasalid species exist in the digestive tracts of termites and wood-eating cockroaches, where they contribute an essential step in the digestion of cellulose ingested by these insects as they bore through wood. Q: Certain anaerobic parabasalid species exist in the digestive tracts of termites and wood-eating cockroaches, where they contribute an essential step in the digestion of this? Choices: - carbonate - fiber - nutrients - cellulose A:
cellulose

Answer the following question given this paragraph: To physically limit radiation doses, we use shielding, increase the distance from a source, and limit the time of exposure. Figure 32.10 illustrates how these are used to protect both the patient and the dental technician when an x-ray is taken. Shielding absorbs radiation and can be provided by any material, including sufficient air. The greater the distance from the source, the more the radiation spreads out. The less time a person is exposed to a given source, the smaller is the dose received by the person. Doses from most medical diagnostics have decreased in recent years due to faster films that require less exposure time. Q: Shielding should be used when receiving x-rays to limit exposure to what potentially harmful form of energy? Choices: - pollution - convection - evaporation - radiation A:
(Answer)
radiation
Ques: Answer the following question given this paragraph: Myopia is commonly called nearsightedness. People with myopia can see nearby objects clearly, but distant objects appear blurry. Myopia occurs when images focus in front of the retina because the eyeball is too long. This vision problem can be corrected with concave lenses, which curve inward. The lenses focus images correctly on the retina. Q: Myopia is commonly called what? Choices: - farsightedness - blindness - scoliosis - nearsightedness A:
Ans: nearsightedness
(Q).
Answer the following question given this paragraph: Renewable resources can be replaced by natural processes as quickly as they are used. Q: What can renewable resources can be replaced by? Choices: - change processes - human processes - fossil fuels - natural processes A:
(A).
natural processes
Ques:Answer the following question given this paragraph: The continental slope is the slope that forms the edge of the continent. It is seaward of the continental shelf. In some places, a large pile of sediments brought from rivers creates the continental rise. The continental rise ends at the ocean floor. Much of the ocean floor is called the abyssal plain. Q: What do you call the slope that forms the edge of the continent? Choices: - the land slope - the prevalent slope - the cataclysmic slope - the continental slope A:

Ans:the continental slope
Ques:Answer the following question given this paragraph: Oil spills are another source of ocean pollution. To get at oil buried beneath the seafloor, oil rigs are built in the oceans. These rigs pump oil from beneath the ocean floor. Huge ocean tankers carry oil around the world. If something goes wrong with a rig on a tanker, millions of barrels of oil may end up in the water. The oil may coat and kill ocean animals. Some of the oil will wash ashore. This oil may destroy coastal wetlands and ruin beaches. Q: What source of ocean pollution kills animals by coating them? Choices: - plants spill - grain spill - chemical spill - oil spill A:

Ans:
oil spill
