.... not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the Big Bang model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler effect which states that if a galaxy is moving away, the spectral line of that galaxy .....

.... it directly. By hitting the earth's surface at an angle there is not as much radiation warming the surface. As the earth rotates and the sun moves further north the temperature increases and the weather turns warmer. During the three months of spring the sun continues to move north and warming the earth more efficiently. At around June 21st the sun is directly facing the tropic of cancer. At this time the movement north comes to a halt and the earth's surface is at its warmest point, the summer solstice. It is also known as the longest day of the year when the earth is furthest a .....

.... the hare grows a new coat of brown fur. Another hare that changes color is commonly called the snowshoe rabbit. The hare has strong hind legs that enable it to hop 43 miles per hour (69 km/h), as fast as a race horse. Lagomorphs must be able to hop about quickly to escape from predators. Another lagomorph, the pika, dwells among the craggy mountain slopes of Asia and North America. In late summer the little pika might be seen guarding a stack of freshly cut hay with determination. A pika bites off tender shoots of grass and plants and piles them up into stacks 2 to 3 feet (60 to 90 cm) .....

.... bouquet of flowers complete. It is very hard to get any Geraniums to grow in short and cold growing seasons, like in the Pacific Northwest. It was very easy to grow and pick the beautiful flowers in the south. Wisteria is in the legume family of woody, climbing plants. The best know Wisteria are Chinese, but American are just as good. Most people use them for crawling things to go over doorways and porches. Porches in the south were a very important place of the house. To have really colorful plants meant that it was a very happy place to be on warm summer night looking at all the di .....

.... variously thought of as a symptom of psychological or social stress or as a learned, maladaptive coping behavior. More recently, and probably more accurately, it has come to be viewed as a complex disease entity in its own right. Alcoholism usually develops over a period of years. Early and subtle symptoms include placing excessive importance on the availability of alcohol. Ensuring this availability strongly influences the person’s choice of associates or activities. Alcohol comes to be used more as a mood-changing drug than as a foodstuff or beverage served as a part of social custom o .....

.... traditional engineering subjects and living systems. He/she may work applying the patterns of living organisms to engineering design or engineering new approaches or products to improve human health and productivity. On the one hand, the biomedical engineer may use his/her knowledge of physiological systems to reverse engineer nature, creating, for example, artificial tissues and neural networks. “On the other hand, a biomedical engineer may use knowledge of engineering to create new equipment or environments for maximizing human performance, accelerating wound healing, providing non-i .....

.... process called photosynthesis. This converts light energy into the chemical bond energy of carbohydrate which is utilized as cellular energy, plant growth and development. Water, carbon dioxide, nutrients and minerals are also needed for survival. In wetlands, where stagnate water contains acidic compounds and chemicals from decaying organic matter many plants have a difficult time obtaining necessary nutrients. It is in these nutrient poor conditions that some plants evolved different ways of obtaining nutrients. The ability of carnivorous plants to digest nitrogen -rich animal .....

.... a few weeks each larva spins a cocoon around itself and pupates. In a few more weeks, adult workers emerge. It is their job to hunt for food and make the nest bigger. More workers will develop and the colony gets very organized. The new workers will completely take over as caretakers of the eggs, larvae, and pupae. Now the queens only duty is to lay more and more eggs, thousands of them in her lifetime. Many wingless workers develop and help to enlarge the nest into an intricate network of tunnels and chambers that will eventually house thousands of ants. When the colony .....

.... disk. When the power of computers increased, so did the possibilities of CADD. Images on CADD systems are drawn with the aid of a keyboard, mouse, or tracking ball. One selects the starting point of a line, the ending point, and the line is drawn. A scale at the bottom of the screen tells how long the line will be. On some CADD systems, the computer itself can measure how long the line will be while the operator inputs the length of the line. Lines are the basis of all drawings. Straight lines are fairly simple and quick to make, but what about curved or wavy lines? That's what differ .....

.... change are responsible for the disappearance of species. For example, as tropical forests are cut down, primates have progressively smaller feeding and living spaces. They also become more accessible to hunters, who kill monkeys for food and trap many primates for sale as pets, research animals, and zoo specimens. Some animal species may move into human communities when their own are destroyed. Extermination of marauding monkeys, roaming tigers, or foraging deer is easy to justify by people whose livelihood is threatened. Pollution is another form of environments change. Forty sp .....
