    Which of the following is the name of a play? A. Blazing Saddles. B. Guess Who’s Coming to Breakfast. C. Importance of deciding basic goals of the Women’s Union. D. Unskilled Labors on Rivers and Canals in Upper Canada, 1820 - 1850. 答案:74-76 DCA E Fish Ears Tell Fish Tales Fish have ears. Really. They’re quite small and have no opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths . As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate . By looking through a microscope and counting these rings, Thorrold can determine the exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about the fish’s age, just like the growth rings of a tree. Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They’re examining the chemical elements of each otolith ring. The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring. Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history. In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many hundreds of miles. This is important to managers in the fish industry, who know nearly nothing about the whereabouts of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists are now lending Thorrold their ears. 【查看更多】
