... expanded and cooled. Several million years later, it condensed into galaxies. The universe has continued to expand, and the galaxies have continued moving away from each other ever since. Today the universe is still expanding, as astronomers have observed. The Steady State model says that the universe does 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 f ...

... The car should stay in that spot. This state of being is called inertia. All of a sudden the wind picks up or some kid crashes into the car with a bike. Both the wind and the kid's bike crashing into the bike are unbalanced forces. The car should start to move. The car might accelerate to two miles per hour. Now we would all assume that the car would come to a stop sometime. We assume this because it is true. It is true because there is friction between the tires and the road. The car now has inertia in uniform motion. Since there is friction, the car cannot keep moving forever because friction is an unbalanced force acting upon the tires. What if t ...

... age faster. Good management enhances the effect of PST. Research has made an indication that pigs that have been treated with PST are leaner. Their meet is very similar in color, taste, tenderness, and juiciness to those who have not received PST. As pigs grow closer to market weight, they produce less PST, which results in poor feed efficiency. The muscle gain stays fairly constant while more nutrients taken in by the animal are used in fat production causing the animal to require more energy for the production of muscle. Manufactured PST will provide a boost in the natural levels of PST in a maturing pig. If there is more PST, there will be more efficient u ...

... months. That is why 20% water changes every two weeks is essential to healthy fish keeping. It generally takes a tank 21 days to cycle. During those 21 days there are 3 days where the ammonia spikes to a large amount and 2 days later on when nitrites spike generally. There are 2 types of filtration for fish tanks biological and mechanical. Biological is what I spoke about in the previous paragraph. Those bacteria grow best on objects besides gravel. That is why having plastic plants and other décor in the tank doesn’t just make the tank look nice but also give the bacteria a better place to grow. Mechanical filtration aids in biological filtration in two wa ...

... Association) reported in January of 1997 that 200 macro viruses had been discovered. Six months later the amount of macro viruses had risen by over 300%. At this stage it is estimated that 90% of all companies have at least one macro virus resident somewhere in their computer systems. Types of Viruses Under the main heading of viruses are three types of harmful computer programs, not all of which hide and replicate. The first of these is the Trojan Horse programs, the name of which comes from the Greek legend that told how Greek soldiers gained entry to the city of Troy in a giant, hollow wooden horse and thus captured the city, ending the Trojan War. ...

... 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. This vehicle combination in my opinion is ...

... how it is created. Charles Darwin originated the idea of evolution. Another theory that is used to explain the origin of life is the big bang theory that states that life was created from a cosmic explosion. Yet another theory on the origination of life is the existence of God and that God created the earth and all of the life on earth. Victor Frankenstein is exactly like the scientists of today. Victor Frankenstein is trying to make a human being from other, deceased human beings, this could be compared to cloning today, making one creature from another. The possibility, or theory of genetic engineering can guarantee that humans would be without deformity, af ...

... branches. Known as brachiation, this method of locomotion is so fast that can easily overtake a person running on the forest floor. The great apes include the gorilla, the orangutan, and two species of chimpanzee: the common chimp and the bonobo (sometimes called the pygmy chimpanzee). Great apes are bigger than and also much less acrobatic. However, they are still good climbers. While orangutans spend most of their life in trees, where they use their long arms and dexterous hands and feet to grasp branches and vines, chimpanzees frequently come to the ground to feed. Gorillas are primarily terrestrial, but even fully grown adult males have been observed clamb ...

... time can’t be turned back and much damaged has already occur. Air Pollution Factories and transportation (like cars or planes) depend on huge amounts of fuel every year. When these fuels burn they introduce smoke and other, less visible, by-products into the atmosphere. Although wind and rain occasionally wash away the smoke given off by power plants and cars, the cumulative effect of air pollution poses a grave threat to humans and the environment. In many places smoke from factories and cars combines with naturally occurring fog to form smog. Smog has been long recognized as a potential cause of death, especially for elderly persons and those with severe respi ...
