.... and ducks, a nesting habitat for herons and rails, and a source of nutrients for estuarine waters. Marshes are important in flood control, in sustaining high-water tables, and as settling basins to reduce pollution downstream. Despite their great environmental value, marshes are continually being destroyed by drainage and filling. Marine Life, plants and animals of the sea, from the high-tide mark along the shore to the depths of the ocean. These organisms fall into three major groups: the benthos, plants such as kelp and animals such as brittle stars that live on or depend .....

.... deserts, where they grow almost entirely underground and obtain light and moisture through small openings in the ground. Few grow near cities because most cannot survive in industrial air pollution. There are notable exceptions, however: in England, for example, Lecanora conizaeoides is actually confined to areas of high pollution. The body of the lichen, the thallus, has three basic growth forms. These forms are crustose, foliose, and fruticose. Each form is adapted to live under different moisture conditions. The crustose resemble a crust that has become attached to a surf .....

.... how hypnosis works, one has to understand the four different activity levels of the human mind. The first level is called beta. In beta the mind is in complete consciousness. Approximately 75 percent of this level is spent regulating vital bodily functions such as heartbeat, breathing, and digestion. The second state is called alpha. Alpha refers to when the mind is in 95 to 100 percent concentration. When hypnosis is induced, the mind is in the alpha level. In this state the mind is fully aware and conscious, but the outside appearance of the body suggests the perso .....

.... An acidic catalyst works due its acid nature. Catalysts are strong acids and readily give up hydrogen ions, or protons: H+. Protons can be released from hydrated ions, for example H3O+, but more commonly they are released from ionisable hydroxyl groups (R-OH) where the O-H bond is broken to produce R-O- and H+. When the reactant receives protons from an acid it undergoes a conformational change, (change in shape and configuration), and becomes a reactive intermediate. The intermediate can then either become an isomer by returning a proton to the catalyst, or it may under .....

.... in certain area the muscles may become paralyzed due to the damage of the nervous system. Many times since people loose feeling in certain areas of their body, injuries occur to them that are unnoticed and become infected. After the disease has settled into ones body it starts to eat away at thebones causing people to loose parts of their body. All of these signs can be prevented with early detection.In the past chaulmoogra oil was used, thinking that it would make a good treatment for . In today's world there are many drugs that are used to prevent it.The drugs are the best .....

.... on gasoline, which is a mixture derived from petroleum. Gasoline contains hundreds of different hydrocarbons, or compounds containing the chemical elements carbon and hydrogen(Gasoline). When the gas is burned in the engine of the car, several byproducts result. These exhausts include hydrocarbons and oxides of three elements: Carbon, nitrogen, and sulfur(Emissions). Tiny amounts of poisonous trace elements such as lead, cadmium, and nickel also are present. Everything contained in the exhaust affects the environment intensely. Auto engine exhaust contributes about 50% of .....

.... and is named for its golden appearance. It is a member of the hawk family. It has a wingspan of six and a half to seven and a half feet, and can live to be thirty or more years old. The adult golden eagle is evenly dark below, or with a lighting at the base of its tail. An immature golden eagle shows a white flash in the wing at the base of the primaries, and a white tail with a broad dark terminal band. The golden eagle is found in the mountainous regions of the Northern Hemisphere, and is a partial migrant. The golden eagle eats rodents, snakes, birds, and can eat .....

.... is a form of life-support on spacecrafts, helping astronomers' hearts pump while they are outside of the Earth's atmosphere. It is used, on Earth, for those who's hearts have problems with pumping blood. Pens that write upside-down are used in space, where there is no gravity and writing with pens would otherwise be impossible. They are convenient tools on Earth when we are trying to write on vertical surfaces. A zero-gravity training system is used to help astronauts become more comfortable with the conditions in space. It is used in places such as Sportsland, for .....
