　　Biological class
　　We spend looking at for a biological perspective. And someone asked with the attendance to be fillfull djl. Some studies indicate that mammal still to some degree. In one study for instance, a group of mice placed in the bright open buck for the now hiding places. Some of the mice wondered
　　Around the bars and didn’t appear to be bothered about being so exposed. But other mice didn’t move. Which indicate they were afraid? Well, when ferful mice or you might say anxious mice like ones stayed in one place. When mice like this bread but one another were repeat, after about 12 also generation. Then all of the offspring show similar sign for ferful mice. And even when the new born mouse from this generation with rice by a mother, and with other mice were not ferful, mice still attend to be ferful as the dot. Now, why is this? Well, it’s sought that the gene specific have influence the anxious behavior. This gene that associated with particular nerve in brain. And the degree of overall ferful mice in the mammal seem to depend in the large part. The present all expense this nerve cell seperator. And this appears to apply to umans and well by the way. But well the attandency talled may will be in trade. The specic form that take has more to do individual environment. So a pectuliar affair likes the ferful snake or the ferful spider not attk. But overall the attendance to have ferful is.
　　43. What is the talk mainly about?

　　45. According to the professor, what contribute to a mammal tendency to be ferful?
　　46. Why does the prof. Mentions snakes and spiders?
　　Listen to a part of talk in the geology class.
　　One type of natural springe geography interest is a teasin spring. Hiking through the world some of to see water flowing from the opening ground. That will no more ever. That may tension spring. To help you understand why water might flow like underground. I‘d like to experience two basic condition necessary for there formation. The first condition is the water not be contain. And acrofer isn’t underground layer of rock sediment that has poles or holes in it. And this poles rock allows water to flow it freely. The acrofer must be inclined so that the over the surface of the ground. Rain water enters this through exposed and traveled downward to the lower portion of the acrofer. The second condition is that above and below the acrofer there must be layer of none rock or clay. Either code acclouds, and they block or hinter the flow of water. Acclouds prevent water from draining out acrofer. So, let us go back to our tension spring. There usually located above the ground near the lower and wind clind acrofer. A tension spring there places some hole crack stand from the ground surface, down through the acrocolud. And into the acrofer. Now the rain moder that had drained into the acrofer makes expose up raind created pressure at the low raind .so if there is crack in the rock, a cracked that run from the acrofer surface, then the pressure pushes the water up through it. And water constrately out of the tension spring.
　　47. What is the topic mainly about?
　　48. Why are the acroclode important to the development of the tension spring?
　　49. According to the prof., how does water in the acrofer reach the ground surface?
　　50. What does the prof. Say about the pressure
