Dolphins Dolphins use a process called sonar to find their way and to find food. They emit sound waves that bounce off objects and return, giving the dolphin information about distance, size, and density. Some scientists think the dolphins can even “turn up” these sound waves and stun their prey. They know that certain levels of sound waves could easily kill a large squid in a matter of minutes. If these scientists are correct; dolphins could easily kill each other—yet they don’t.

Boomerang Children In recent decades more young adults are returning to their parents’ homes. Most parents express satisfaction with the arrangement, especially when it is temporary and when the adult child is under age 22. Parents appreciate help with household chores and with caring for younger children, and they enjoy sharing leisure activities. Usually everyone is active and healthy. But serious conflicts may arise, especially when a young adult is unemployed and financially dependent. Disagreements may center on household responsibilities and the child’s lifestyle: dress, sex, alcohol, drugs, and choice of friends. The young adult is likely to feel isolated from peers and to have trouble establishing intimacy, while the parents may have to postpone renewing their own intimacy, exploring personal interests, and resolving marital issues. The most difficult situation for parents seems to be the return of divorced or separated children with their own children. Question at position 4 0.5 points Question 4 is unpinned. Click to pin.

FM and AM Radio In the early days of radio, one factor that kept FM radio from developing as much as AM was that more people had AM receivers than FM receivers. Radios that could receive both AM and FM had not yet become popular, and it was not possible to pick up FM on a standard AM radio. Moreover, many of the same people who owned AM stations owned FM stations; to simplify the programming effort, they would broadcast the same show over both frequencies. Third, after World War II, the Federal Communications Commission (FCC) moved FM from the place it had originally occupied on the broadcast spectrum; this made all existing FM radios useless.
