Above were just a few things that caused habitat loss or change. There are many ways in which living organisms can affect their ecosystem. In some areas, it is because of fire management. Fire is a natural event, so managing fire correctly is very important. In other areas, fisherman have taken too many fish from one area. This places the species at risk of extinction. It also affects other living things that may rely on these fish for food. The image below shows a picture of a mine. Mining changes the Earths surface. This area may once have been a forest or a prairie. Think about how many plants and animals may once have lived here. Now it is a giant hole in the ground. Pollution is also a major factor in habitat loss and change.

Question: "Is it possible for a living organism to affect their ecosystem?"

OPTIONS:
- no
- yes

Answer: "Possible"

Response: yes

You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.

Question: "What can happen in a car when there is too much friction?"

Response: "The tires pop"

Problem: On his return to Nuremberg in 1495, Durer opened his own workshop (being married was a requirement for this). Over the next five years his style increasingly integrated Italian influences into underlying Northern forms. Durer's father died in 1502, and his mother died in 1513. His best works in the first years of the workshop were his woodcut prints, mostly religious, but including secular scenes such as The Men's Bath House (ca. 1496). These were larger and more finely cut than the great majority of German woodcuts hitherto, and far more complex and balanced in composition. It is now thought unlikely that Durer cut any of the woodblocks himself; this task would have been performed by a specialist craftsman. However, his training in Wolgemut's studio, which made many carved and painted altarpieces and both designed and cut woodblocks for woodcut, evidently gave him great understanding of what the technique could be made to produce, and how to work with block cutters. Durer either drew his design directly onto the woodblock itself, or glued a paper drawing to the block. Either way, his drawings were destroyed during the cutting of the block.

Question: "Durer's workshop scene "The Men's Bathhouse" was established in what year."

Answer: "After he returned to Nuremberg"

- no
- yes
Answer: no

Question:
You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below. After reading the above, is "Because of motion present in air molecules, water drops, and ice particles" the correct answer to the question "How do clouds develop different regions of charges?"? OPTIONS:
- no
- yes

Answer:
yes

Input: Renewable Energy Resource Sunlight Sunlight can be used to heat homes. It can also be used to produce electricity. This conversion is made possible by solar cells. However, solar energy may not always be practical. Some areas are just too cloudy. Example Solar panels on the roof of this house generate enough electricity to supply a familys needs. Moving Water Falling water can have a lot of energy. Its energy can be converted into kinetic energy. This energy can turn a turbine and generate electricity. The water may fall naturally over a waterfall or flow through a dam. A drawback of dams is that they flood land upstream. They can also reduce water flow downstream. Either effect may harm ecosystems. Wind Wind is moving air. It has kinetic energy that can do work. Wind turbines change the kinetic energy of the wind to electrical energy. Only certain areas of the world get enough steady wind. Many people also think that wind turbines are noisy and not very nice to look at.
"What is the drawback of kinetic energy from hydro power?" is "Flooding upstream, not enough water downstream"?

OPTIONS:
- no
- yes

In India to purchase some horses , British aristocrat , Lord Esketh and his wife , Edwina , come to the town of Ranchipur at the invitation of the elderly Maharani . Their marriage is an unhappy one and Lord Esketh announces his intention to return to England and begin divorce proceedings . The spoiled , insensitive Edwina scoffs at this .

She also meets and attempts to seduce a distinguished Hindu physician , Dr. Rama Safti , a decent man who is the elderly Maharani's personal choice to succeed her someday . Safti at first resists , but ultimately succumbs to Edwina's charms and falls hopelessly in love with her . Lord Esketh becomes aware of this , but Safti saves him from a man-eating tiger during a safari . Safti admits his love for Edwina to Lord Esketh , who is now sympathetic toward this good man's plight . Ransome feels the same way , warning Edwina to stay away from Safti , a friend he admires . Edwina similarly falls into disfavor with the Maharani , who explains that Safti has been raised to lead a pure life and that Edwina is unworthy of him . Ranchipur suddenly is ravaged by a natural disaster , an earthquake and flood . Dr. Safti is so busy saving lives that he can not personally care for Edwina , who has fallen ill . Ransome looks after her as well as for young Fern Simon , who has declared her love for him . When a dam is exploded by dynamite and as a result the flood waters recede , it is Dr. Safti who reveals that Ransome is the one who risked his personal safety to save the people of Ranchipur .
