.... bright orange regions and darker ,less red areas the outlines and tones change in martian seasons.The reddish color is because of it's heavily rusted surface.The dark areas are thought to have rocks that are simmilar to terrestrial basalts, the surface is even more weathered and rusted.The brighter areas seem to have similar but even more weatherd and rusted material that apparently contain more fine, dust-sized particles than they do the dark reigons. The mineral scapolite,which is rare on Earth,seem's wide spread; it may serve as a store for carbon dioxide in the atmosphere. Bright caps, apparntly made of frost or ice, mark the planet's polar regions . their seasonal cycl ....

.... the other end of the spectrum are the other invisible radiations, ultra- violet, X rays, micro waves and gamma rays. The wavelength of the light is important to the subject of the laser. A laser is made up of COHERENT light, a special kind of light in which the wavelengths of the light are all the same length, and the crests of these waves are all lined up, or in PHASE. The word Laser is an acronym for Light Amplification by Stimulated Emission of Radiation. What does that mean? Basically a laser is a device which produces and then amplifies light waves and concentrates them into an intense penetrating beam. The principles of the laser (and it's cousin the maser) were ....

.... minerals found within it's body. This gave the three swords an almost wood grain effect to their blades. Since the iron in the swords was not pure they were quite difficult to make for the master swordsmith Kinimune Okayoshi. Forging it by folding it over and over did not work out very well. So the forging could only be carried out when the metal had gotten so hot it turned white. Although somewhat irrelevant to the short story about the Shooting Star Swords, meterites do play an important part in science to day, and help scientist decode the birth of earth, our sun, and even the galaxy in which we are in. Today whenever a meteorite is found it is closely strdied by t ....

.... ants), deer and moose fawns, carrion and in coastal areas on spawning salmon. Their habitat includes forests with occasional open areas such as meadows. They occupy all of Canada starting from the tree line going south. They live in all provinces and territories except Prince Edward Island, where heavy de-forestation has happened and preferably away from brown bears (larger competitors). The only main risk for black bears are poachers who sell their parts illegally to the Asian medicinal market. In northern areas of Canada, the bear undergoes a remarkable metabolic transformation as it prepares for hibernation. Hibernation is an energy-saving process bears have develop ....

.... areas in which acid attacks have already begun. The remineralization effect of fluoride is important because it reverses the early decay process as well as creating a tooth surface that is more resistant to decay. Community water fluoridation is the adjustment of the amount of the beneficial trace element fluoride found in water to provide for the proper protection of teeth. Fluoridation has been widely utilized in this country since 1945. It does not involve adding anything to the water that is not already there, since virtually all sources of drinking water in the United States contain some fluoride. Fluoridation is a form of nutritional supplementation that is not ....

.... depend. Of even greater importance to humans are the indirect benefits reaped from the entire plant kingdom and its' more than 3 billion years of carrying out photosynthesis. Today the world's biomass is composed overwhelmingly of plants, which not only underpin all food webs but also modify climates and create and hold down soil, making what would otherwise be stony, sandy masses habitable for life. Cell Structure and Function The tremendous variety of plant species is, in part, a reflection of the many distinct cell types that make up individual plants. Fundamental similarities exist among all these cell types, however, and these similarities indicate the co ....

.... beetles play all around the world. I remember several days when I was young that I would just go for a walk in my grandfather's pasture. I would enjoy the quiet walks, and sometimes try to scare the cows, but more often than not, I would end up stopping to watch dung beetles frantically work on a big cow pat. I remember how disgusting it appeared, but I was just fascinated at the concept of cow poop being rolled into balls and taken away by bugs. To realize why dung beetles are so important, you must first know a few facts about them. Dung beetles are named after their delight in rolling up dung. Dung beetles utilize the dung of cows, horses, rabbits, deer, sheep, and ma ....

.... less than 30 miles per hour the electric motor does the greatest amount of the work. As the cars power sources begins to lose some of its energy the backup gasoline engine starts. This function is similar to how gasoline cars work, with the alternator using the engine's power to recharge the battery. After the power supply is replenished the gasoline engine shuts down. Also the gasoline engine is used to power the vehicle as it reaches the higher speeds where the added horsepower is needed. Usually the speed at which the gasoline engine starts is in the 30 mile per hour range. Even as the gasoline engine runs the electric motor continues to provide power for the vehicle. T ....
