When you get sick, your body springs to action. Your body starts to fight the illness. Thats why you want to eat right and get plenty of sleep. You need a strong immune system to fight off illness. Plants dont have an immune system. That does not mean they do not get sick. Plants are affected by disease just like us. Typically, their first line of defense is the death of part of the plant. This prevents the infection from spreading. Many plants also produce special chemicals to fight disease. For example, willow trees produce a chemical to kill the bacteria. The same compound is used in many acne products. You can see a picture of a willow tree in Figure Plants may be smarter than we think. No, they cannot talk to each other. They may be able to send messages, though.

Answer: How might death of part of a plant help the plant?

The Bush administration did not develop new diplomatic initiatives on al Qaeda with the Saudi government before 9/11. Vice President Cheney called Crown Prince Abdullah on July 5, 2001, to seek Saudi help in preventing threatened attacks on American facilities in the Kingdom. Secretary of State Powell met with the crown prince twice before 9/11. They discussed topics like Iraq, not al Qaeda.U.S.-Saudi relations in the summer of 2001 were marked by sometimes heated disagreements about ongoing Israeli- Palestinian violence, not about Bin Laden. The confirmation of the Pentagon's new leadership was a lengthy process. Deputy Secretary Wolfowitz was confirmed in March 2001 and Under Secretary of Defense for Policy Douglas Feith in July. Though the new officials were briefed about terrorism and some of the earlier planning, including that for Operation Infinite Resolve, they were focused, as Secretary Rumsfeld told us, on creating a twenty-first-century military. At the Joint Chiefs of Staff, General Shelton did not recall much interest by the new administration in military options against al Qaeda in Afghanistan. He could not recall any specific guidance on the topic from the secretary. Brian Sheridan-the outgoing assistant secretary of defense for special operations and low-intensity conflict (SOLIC), the key counterterrorism policy office in the Pentagon-never briefed Rumsfeld. He departed on January 20; he had not been replaced by 9/11. Rumsfeld noted to us his own interest in terrorism, which came up often in his regular meetings with Tenet. He thought that the Defense Department, before 9/11, was not organized adequately or prepared to deal with new threats like terrorism. But his time was consumed with getting new officials in place and working on the foundation documents of a new defense policy, the quadrennial defense review, the defense planning guidance, and the existing contingency plans. He did not recall any particular counterterrorism issue that engaged his attention before 9/11, other than the development of the Predator unmanned aircraft system. The commander of Central Command, General Franks, told us that he did not regard the existing plans as serious. To him a real military plan to address al Qaeda would need to go all the way, following through the details of a full campaign (including the political-military issues of where operations would be based) and securing the rights to fly over neighboring countries. The draft presidential directive circulated in June 2001 began its discussion of the military by reiterating the Defense Department's lead role in protecting its forces abroad.

Dam Good Luck: From the beginning, Las Vegas was built to serve travelers. The railroad needed a way station, and Las Vegas was the place. Growth continued for ten years, and by 1915 the town had telephones, round-the-clock electricity, and a growing populationmany of whom worked in the railroad repair shop. But such heady progress would soon come to a halt. The growing competition in rail transport resulted in Union Pacific buying the Los AngelesSalt Lake line. Union Pacific then consolidated its operations, eliminating the Las Vegas repair facility. Additionally, Las Vegas had been made a part of Nevada's new Clark County in 1909, a year when the legislature also outlawed gambling. These unfortunate circumstances threatened to relegate Las Vegas to the status of a small desert community that could no longer support its 3000 residents. But the southwest's growing need for water, combined with Las Vegas's fortuitous proximity to the Colorado River, would give Las Vegas a second chance to achieve prosperity. Construction on Hoover Dam (originally Boulder Dam, subsequently renamed for the president who authorized the project) began in 1931 in a canyon 45 miles (72 km) southeast of Las Vegas. Providing an influx of $165 million to the southwestern economy, Hoover Dam played a major role in preventing Las Vegas from drying up, both financially and literally. Not only did it create jobs, but it also created Lake Mead, the massive reservoir that today provides water to all of southern Nevada. More Government Help: The construction of Hoover Dam did not single-handedly save Las Vegas, however. The state legislature helped as well, by legalizing gambling in 1931 and thus solidifying the future of the town, though legislators and residents could never have known this at the time. The hordes of people who attended Hoover Dam's 1935 dedication set the city's now-formidable public relations machine into action. They went to work on what has become one of the lengthiest citywide tourism campaigns ever attempted. It didn't take long for the city to establish itself as a wild-West town with an "anything goes" attitude. Vices outlawed or heavily controlled elsewhere were legal here, available any hour of any day (or night).
