endocrine disruptors
Answer the following question given this paragraph: Static electricity is a buildup of electric charges on objects. It occurs when electrons are transferred from one object to another. Q: What is the term for the buildup of electric charge on an object, which can be transferred to another when touched? Choices: - electromagnetic electricity - electric potential - static cling - static electricity A:
static electricity
Q: Answer the following question given this paragraph: While many elements differ dramatically in their chemical and physical properties, some elements have similar properties. We can identify sets of elements that exhibit common behaviors. For example, many elements conduct heat and electricity well, whereas others are poor conductors. These properties can be used to sort the elements into three classes: metals (elements that conduct well), nonmetals (elements that conduct poorly), and metalloids (elements that have properties of both metals and nonmetals). The periodic table is a table of elements that places elements with similar properties close together (Figure 1.22). You will learn more about the periodic table as you continue your study of chemistry. Q: What elements tend to conduct well? Choices: - organics - gases - oils - metals A:
A: metals
Question: Answer the following question given this paragraph: Television broadcasts also use radio waves. Sounds are encoded with frequency modulation, and pictures are encoded with amplitude modulation. The encoded radio waves are broadcast from a TV tower like the one in Figure below . When the waves are received by television sets, they are decoded and changed back to sounds and pictures. Q: What are groups of tens to hundreds of thousands of stars held tightly together by gravity called? Choices: - elliptical clusters - elongated clusters - galaxy - globular clusters A:
Answer: globular clusters

Answer the following question given this paragraph: Migration refers to seasonal movements of animals from one area to another. Migrants typically travel long distances, and travel the same paths each seasonal cycle. Usually, the migrants move to another area in order to find food or mates. Many birds, fish, and insects migrate. Mammals such as whales and caribou migrate as well. Figure below shows the migration route of a bird called a godwit. Another example of a behavior with a yearly cycle is hibernation. Hibernation is a state in which an animal's body processes are slower than usual, and its body temperature falls. An animal uses less energy than usual during hibernation. This helps the animal survive during a time of year when food is scarce. Hibernation may last for weeks or months. Animals that hibernate include species of bats, squirrels, and snakes. Most people think that bears hibernate. In fact, bears do not go into true hibernation. In the winter, they go into a deep sleep. However, their body processes do not slow down very much. Their body temperature also remains about the same as usual. Bears can be awakened easily from their winter sleep. Q: The seasonal movements of animals from one area to another is referred to as? Choices: - mitigation - hybernation - echolocation - migration A:
**Answer**
migration
