Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right.

Question: "Is suspended growth required for plants to survive?"

Response: "Yes"

- no

Powell contended that it was not inconsistent to want to foster cooperation even with an organization like the Indonesian military, which has a history of human rights abuses. "If you get young officers, expose them to a military organization that is within a democratic political institution, such as the United States, then that rubs off on them," he said. In Malaysia, Powell met with Prime Minister Mahathir Mohamad, who has led the country since 1981. The Malaysian foreign minister, Syed Hamid Albar, later told local reporters that Powell had proposed that American and Malaysian officials review the idea of forming a regional training center in Malaysia to coordinate antiterrorism activities. His brief stop in Malaysia also highlighted the moral ambiguities of the effort to prevent terrorism and its emphasis on cooperation with governments that the United States has often criticized. The United States once distanced itself from Mahathir for strong-arm tactics with political rivals, and human rights groups criticize him for arresting and jailing scores of suspected militants, including some who may be linked to al-Qaida, without trial. Powell said his discussions with Mahathir "touched on the case" of his former deputy, Anwar Ibrahim, who is serving a 15-year sentence on charges of sodomy and abuse of power after trials that Powell said the United States had "always felt" were flawed. The assistant secretary of state for East Asian and Pacific affairs, James Kelly, met on Tuesday morning with Anwar's wife, Wan Azizah Wan Ismail, for what she later told Malaysian reporters was a discussion about both the detention of her husband and six supporters, and the campaign against terrorism.

Question: "Does Powell think America should work with other governments on counterterrorism efforts, even if those governments have a history of human rights abuses?"

Response: "Yes, he believes it's not inconsistent because exposure to the US military could impact them in a positive way and his trip highlighted thes moral ambiguities"

Have you are burned something on the stove or in the oven? Do you know why things burn? It all has to do with temperature. Changes in matter are affected by temperature. For example, what if you place a cake in the oven and you leave it in too long? What do you think will happen? Thats right, it will probably burn. The same thing will happen if the oven setting is too high and you apply too much heat. In either case, heat has affected the rate of change in matter. Its probably obvious that when the temperature is increased a chemical change, like cooking, will occur faster. What about a physical change? Are physical changes affected by temperature? Most of us have seen steam rising off a wet road after a summer rainstorm. This happens because the road surface is very warm. The warm road and warm air temperature causes the water to evaporate quickly. The liquid water is turning into water vapor, but it is still water. The evaporation of water is a physical change. So yes, temperature affects the rate that physical change occurs.

Question: "Why would steam rise off a wet road after a summer rainstorm?"

Response: "Because the road surface is very cool"
