.... (depression), usually with periods of normal mood in between. Some individuals may display mixed symptoms of both mania and depression at the same time, while others may have fewer symptoms of mania (also referred to as hypomania). The type severity, and duration of mood episodes may vary. Some individuals may experience excessive mania, or excessive depression, and some may experience an equal amount of both. The mood episodes can last for a few days to as long as several months, especially when left untreated or not treated effectively. Usually a person with bipolar disorder can exp .....

.... given the zodiac its name, for in greek, it means "route of animals." The sun enters the first zodiacal sign, Aries , and then continues its path through the remaining eleven signs. The twelve signs of the zodiac are: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. The moon and the planets pass through the signs too, but obviously at different speeds from those of the sun. The moon, which is close to the earth, circles the zodiac in twenty-nine days, while the planet Pluto needs two hundred fifty years. Planets also can b .....

.... length of 1.5 m; have a tail 1 m long; stand 2 m tall; and weigh 90 kg. A gray kangaroo can clear more than 9 m (30 feet) at a bound and attain a speed of 48 kilometres per hour. The wallaroo, a smaller and stockier animal, may be dark gray to pinkish brown; it lives in rocky country throughout Australia except Victoria. These large kangaroos travel in groups (mobs) under the leadership of the largest male ("old man," or "boomer"), which dominates younger rivals by biting, kicking, and boxing. Each long, narrow hind foot has four toes. The short forelimbs are used almost .....

.... is the theory that deals with the structure, history, and dynamics of the earth's crust. The earth's crust is formed of 13 continental plates. The boundaries of the zones are where tectonic activities occur, and where earthquakes and volcanic eruptions tend to happen. The plate tectonics theory was thought up in the 1960s and 1970s, with ideas taken from Wegener’s earlier thoughts. Earlier, Wegener and other scientists had noted that continental crust grows by additions and that a ridge in the middle of the ocean runs almost all the way around the world. It was also noted that cont .....

.... pattern in the largest adult males. The terminal male is the one with the brightest colors and gaudiest patterns. The moon seems to play an important role in fish reproduction. According to Peter H. Pressley, it appears that the moon/s light may be as important as its gravitational pull. "Some fishes may use periods of maximum moonlight for effective nest guarding during the week or so it takes for many demersal eggs to incubate. Since the larvae of many dermersal-spawning species are light sensitive, bright moonlight may help to orient them towards the water's shallows after n .....

.... your sensory receptors may detect a change in your blood temperature, or a change outside of your body such as a touch on the arm. Your body then goes through a process know as its integrative function. This is when your nervous system processes information sent via your sensory neurons and in a way “makes decisions” regarding appropriate responses. When all is said and done during this process a decision is made and sent through interneurons that act as a postman and deliver the decision to the motor function part of your nervous system. The motor function involves responding to t .....

.... times more acidic than rain water, and has been recorded as low as 2.5 on the pH scale (forty times more acidic than water.) Acid deposition kill fish, soil bacteria, and as well as aquatic and terrestrial plants. the acid also drain the soil of essential nutrients such as aluminum and releases them into bodies of water such as streams, lakes, and ponds. These bodies of water develop highly concentrated levels of these nutrients which can really harm the aquatic life forms in that area Those areas without any alkaline metal deposits in the soil to neutralize some of the acid are hurt the mos .....

.... have shown that students shown an increase in problem-solving and critical thing sills, enhanced learning in core academic subjects, produce higher quality work and have even provided more one-on one time between teachers and students (THE Journal 16). Technology is an integral component of learning. Being that students learn at different rates, technology can individualize instruction. They can move at an appropriate pace providing a solid foundation of basic skills. Computer based technologies can administer individualized lesson sequences that branch and remediate according to stu .....

.... that if the distance between electric charges is increased, the force of attraction or repulsion decreases. All matter is made up of very tiny particles called atoms. Atoms are made up of even smaller substances called subatomic particles. Scientific studies have found that some of these subatomic particles are charged with electricity. The electric charges are made up of two kinds - positive and negative. The positively charged particles are called protons, and the particles with negative charges are called electrons. In an atom, the protons are located in the center, or nucleus, and the e .....

.... of medicine. continues to grow every year, which makes it a very important issue in our society, in fact 40% of American use some form of herbal or other in the world today (Jonas). This fact just shows how widely used this method is. According to a survey of 1,539 adults in 1990 and 2,055 in 1997, use of at least one type of alternative therapy during the previous year jumped from 33.8 percent in 1990 to 42.1 percent in 1997 (Mann). These facts show just how fast is growing. The option to ignore the use of is gone. For how much this new method of medicine is growing it is almost i .....
