.... movie theaters, and a sharper picture. What causes this perk is the fact that digital signals have a higher bit rate. This allows for more bits to be transmitted into the TV (cable, antenna, or satellite). The more bits a TV can transmit, the better the picture or screen resolution. The digital TV signal can carry as many as 19.4 megabits of data, which means a broadcaster can mix multiple programs of varying bit sizes onto a single channel. Say you’re watching a football game, since one camera view only uses up so many bits, you can select a different camera angle while watching the same game on the same channel. It is possible for a network, like NBC, to show two d ....

.... the core temperature in an animal. An ectotherm, or cold blooded animal, warms its body mainly by absorbing heat from its surroundings. The amount of heat it derives from its metabolism is negligible. In contrast, endotherms derive most or all of its body heat from its own metabolism (Campbells,p899). Because ectotherms do not produce their own heat, they cannot actively ensure their ideal temperature for an ideal metabolic rate (aquacult.htp). In the following experiment, we will attempt to examine the relationship between metabolic rate and environmental temperature in both an ectoderm and an endotherm. I predict that for the ectotherm, the metabolic rate will increase a ....

.... to see what AIDS truly was in the late 1970’s to early 80’s, mostly in men and women with multiple sex partners located in East and Central Africa, but also in bisexuals and homosexuals in specific urban areas of the Americas, Ausrtalasia and Western Europe. Aids was and is spread still through infected hypodermic needles which drug abusers are affected by, but also through transfusion of the blood and its components. And sadly, whenever a mother is infected, the unborn child will almost positively receive the virus before, during, or after the pregnancy. The viruses which cause AIDS, otherwise known as Human Immunodeficiecy Viruses(HIV) were first discovered in ....

.... These radioactive nucleuses can be contained and used as fuel for the power. Most of this power is fueled by uranium isotopes. These isotopes are highly radioactive. The isotope catches the fast moving neutrons created by the splitting atoms, it repels the slower moving protons and electrons, then gathers the neutrons and pulls them inward. While all these atoms are flying about they smash together then split many of many times, this is when the reactor grabs and pulls in the frictional energy to be processed into electrical watts. This usually causes heat or thermal energy, this must be removed by some kind of a coolant. Most power plants use water or another type o ....

.... the behavior of shrews that have been caught suggests that occasionally they may tunnel through dead leaves and loose soil in search of food. The shrews burrow is a small underground number of shallow tunnles under flat stones or logs. Burrows found in east Texas were about 2.5 cm round, from 25 cm to 1.5 m long, and not more than 20 cm below the surface. Each burrow has a large area at the end for the nest which was composed of shredded grass. These nests were used for young or as a resting place for groups of adult shrews. Compared to most types of shrews, the least shrew is sociable, and several may be kept together in captivity without conflict. They sleep togethe ....

.... has different colors is through the processes involving heat and radiation. Another reason is that 99.5% of a Diamond is Carbon and the rest are different trace elements. These 0.5% of elements are the reason why a Diamond has different color shades. For example Nitrogen causes it to have a yellow tint , and Boron a blue shade. The pink color in some are thought to be caused by deformation of the atomic structure of the diamond crystal. A pure Diamond , which would be 100% carbon, is colorless were created million years ago, when the earth was formed, the material experienced pressure of 5million times the atmosphere at sea level and temperatures between 1000~1200degree ....

.... The first of these methods, and the most important, is blocking adenosine receptors. As caffeine has a similar structure to the adenosine group, but also has more heavily electrophilic and nucleophilic functional groups than adenosine as, for instance, seen in cyclic AMP. This means that caffeine will fit adenosine receptors as well as adenosine itself will. Thus, cyclic AMP remains active, rather than being broken down. Second among the effects of caffeine is phosphodiesterase inhibition. The phosphodiesterase class of enzymes includes a number of enzymes responsible for breaking down cyclic AMP, thus depriving the body of an energy supply. Caffeine fools phosphodiesterase ....

.... of things. First, a Tsunami(tidal wave) would be created on impact. The wave would be hundreds for feet high traveling hundreds of miles per hour. It would start to slow down crashing ashore through all coastal city. Then, finally wash up hundreds for miles inland. " The mid-Atlantic Ocean impact ranging from 400 meters to 5 kilometers in diameter. This would generate a tsunami that would sweep across the upper East Coast of the United States to the Appalachian Mountains."(Gottschalk 1) The blast of the impact would equal a 300 gigaton blast of T.N.T. Also, 2.4 seconds after impact, a small fireball with a temperature of 5000'C would sweep across long island. A land fall ....
