Answer the following question given this paragraph: The outer ear catches sound waves and funnels them to the middle ear. The middle ear amplifies the sound waves and passes them to the inner ear. The inner ear changes the sound waves to electrical signals. The signals travel to the brain, which interprets the sounds. Q: Which part of the ear amplifies the sound waves? Choices: - eardrum - ear canal - cochlea - middle ear A:
middle ear
Answer the following question given this paragraph: The placenta permits a long period of fetal growth. As a result, the fetus can become relatively large and mature before birth. This increases its chances of survival. On the other hand, supporting a growing fetus may be difficult for the mother. She has to eat more while pregnant and may become less mobile as the fetus grows larger. Giving birth to a large infant is also risky. Q: The fetus becoming relatively large and mature before birth increases the chances of what? Choices: - disease - mutations - intelligence - survival A:
survival
Q: Answer the following question given this paragraph: an identical particle that has been ejected from a heavier nucleus. There are six fundamentally different kinds of nuclear decay reactions, and each releases a different kind of particle or energy. The essential features of each reaction are shown in Figure 20.4 "Common Modes of Nuclear Decay". The most common are alphaand beta decay and gamma emission, but the others are essential to an understanding of nuclear decay reactions. Figure 20.4 Common Modes of Nuclear Decay. Q: There are six fundamentally different kinds of nuclear decay reactions, and each releases a different kind of particle or what? Choices: - protein - mineral - mass - energy A:
A: energy
Question: Answer the following question given this paragraph: Most geological activity takes place at plate boundaries. This activity includes volcanoes, earthquakes, and mountain building. The activity occurs as plates interact. Giant slabs of lithosphere moving around can create a lot of activity! The features seen at a plate boundary are determined by the direction of plate motion and by the type of crust found at the boundary. Q: Where does most geological activity take place? Choices: - plate buildings - plate waves - plate medians - plate boundaries A:
Answer: plate boundaries

Answer the following question given this paragraph: Because of global climate change, temperatures all over Earth are rising. However, the melting points of Earth's substances, including ice, are constant. The result? Glaciers are melting at an alarming rate. Melting glaciers cause rising sea levels and the risk of dangerous river flooding on land. You can learn more about these effects of melting at this URL: http://video. nationalgeographic. com/video/player/environment/global-warming-environment/glacier-melt. html . Q: What is occurring at an alarming rate as a result of global climate change and the constant melting point of ice? Choices: - glacial movement - glacial hardening - glacial formation - glacier melt A:
(A).
glacier melt
