.... fluids, and brass are also solution. A solution is a homogenous mixture of two or more substances in a single physical state. Solutions are all around you. All solutions share several important properties. The particles in a solution are very small. In fact, they are atoms, molecules, or ions, which is why you cannot see them. The particles in a solution are evenly disturbed, or intermingled informally on a molecular level. A small sample of one part of a solution. The particles in a solution will not separate no matter how long the solution is allowed to stand under constant conditions. In a solution, one substance is usually considered to be dissolved .....

.... that will inevitably occur if the citizens of the world do not realize the seriousness of this problem. To better understand the importance of the rainforest, one must be knowledgeable about what a rainforest actually is. The two main types of rainforests are temperate and tropical. Tropical rainforests are located in Latin and South America, Africa, Southeast Asia, and other areas in which temperatures stay above 80 degrees Fahrenheit year round. They can be found in 85 countries all over the world, however, 90 percent of them are concentrated into fifteen countries, each containing over ten million hectares. Tropical rainforests receive 160 to 400 inche .....

.... the DNA from a six-year-old ewe and fused it with the egg of another ewe after removing the second ewe's own DNA. After fusing, the cell began to divide as would a regular embryo. The embryo was then implanted in a third ewe who only a few months later gave birth to Dolly 1 . Upon news of this, many people began to question the possibility of not only creating genetically identical sheep, but humans as well. There has been much controversy on whether or not the cloning of humans as well as animals is ethical or even moral. Also there has been much discussion as to whether or not the benefits of cloning outweigh the dangers. WHAT ARE THE BENEFITS IN C .....

.... gene is passed from mothers who carry it to their sons. The mothers have subtle eye changes which an ophthalmogist could identigy, but mothers usually have normal vision. For each son born to a mother who carries the gene, there is one in two chance of having X-linked ocular . The description is a hereditary deficiency pigmentation. This could involve the entire body or part of the body. This is believed to be caused by an enzyme deficiency involving the metabolism of melanin during prenatal development. This can be inherited by an dominant or recessive trait. In complete , there is lack of pigmentation in skin and hair, as well as in retinal and iris tissue .....

.... countries, technologically advanced countries, and those in between are at the mercy of these microorganisms, which come in many forms - viruses, bacteria, fungi and parasites. The most dangerous of these forms is the virus. Some viruses, such as the common flu, are considered to have a fairly detrimental capacity. The flu can incapacitate a human for several weeks with various symptoms such as bodily soreness, fever, bronchial complications, and even pneumonia. But while these conditions can be painful and frightening, we are usually confident that proper medication and rest will take care of the matter. However there is a much more severe and indiscriminate .....

.... a silent killer has made it's way into your home. This killer shows no remorse. It strikes men, women, and children. It does not care what color you are, nor does it care what nationality you are. The killer is carbon monoxide. Carbon monoxide, or CO as it is also called, is an odorless, colorless, and deadly gas given off when any fuel is incompletely burned by, for example, a furnace or water heater (Marable 97). Unlike a fire where you can immediately see smoke and flames, carbon monoxide poisoning gives no physical evidence of its presence. But, when taught to see and look for the warning signs of carbon monoxide, deaths in the home due to carbon mo .....

.... of beach sand; some beaches are built to great widths by sediments washed to the sea by episodic floods, gradually eroding until the next major flood replenishes the sand. Beach formation begins as eroded continental material--sand, gravel, and cobble fragments--is washed to sea by streams and rivers. Two separate processes result in the deposit of this sand and sediment on the shore. Most sediment is suspended in sea water and transported along the coast by the longshore current, a stream of water flowing parallel to the beach that is created by the action of waves breaking at an angle to shore. Longshore transport can deliver up to a million cubic yards of .....

.... Sumatran tiger has the most stripes of all the tiger subspecies, and the Siberian tiger has the fewest stripes. Tiger stripes are like human fingerprints; no two tigers have the same pattern of stripes. The tiger's head often carries the Chinese mark of wang or king on the forehead. Most tigers have an orange coat with dark brown or black stripes accented with white. Tigers that live in cold climates (Siberian tigers) have thicker fur than tigers that live in warm climates. A tiger's tail is 3 to 4 feet long, about half as long as its body. Tigers use their tails for balance when they run through fast turns. They also use their tails to communicate with ot .....
