Cancer 2

... A normal human body cell has 46 chromosomes, which contain an average of several thousand genes each. During certain phases of the cell's life cycle, the chromosomes are stretched out into long, thin strands, and they are tangled together into a network called chromatin. In addition to genes, chromosomes contain proteins, some of which cover the genes that are not "turned on" at the particular time. The original genetic information, stored in a coded form DNA, is carried out of the nucleus by RNA and then translated into proteins by ri ...

Lasers 2

... Different wavelengths of light are seen as different colors. Like radio waves, light can also carry information. The information in the beam varies in the frequency or shape of the light wave. Because light waves are of much higher frequencies than radio waves, the have a higher information carrying capacity. In beams of light,individual photon waves are not moving along together because they are not being emitted at the same instant but instead in random short bursts. Such beams are called incoherent. The process for laser act ...

The Evils Of Hunting

... and there is challenge to the sport. However, when land- owners encounter a slob hunter on their lands, they are much less likely to let anyone hunt their land in the future. When a person wishes to hunt on a certain person's land, s/he is often denied the privilege, after the proprietor of the land has had one negative experience with some other hunter. This can make hunting a much harder sport to participate in, even for the people who are hunting for their livelihood. (Satchell 30) Over the years, hunting has reduced the animal population ...

Newton's Laws Of Motion

... object, or change its motion while it is moving. There is an unseen force called friction. Friction is a force between two surfaces that works against movement. One surface tends to work against, or resist, any motion of the other surface. For example, there is a friction between a wood floor surface and the surface of a rubber ball when it is rolled across the floor. The floor surface resists the motion of the rubber ball surface. This resistance or friction will slow down the moving object and eventually bring it to a stop. Frictio ...

Dinosaurs

... who named them iguanodon. About the same time, other fossil teeth and bones were found near Oxford, England, by Rev. William Buckland. These were named Megalosaurus. Thousands of specimens have since been discovered nearly worldwide. Different types of dinosaurs varied greatly in form and size, and they were adapted for diverse habitats. Their means of survival can only be identified from their fossil remains, and some identifications are in dispute. They ranged in weight from 4 to 6 lb., in the case of the compsognathus, and up to ...

Computer Viruses

... virus. A boot sector virus infects the. When the infected boot program executes, the virus is loaded into the computer’s memory. Once the Virus is in memory, it can spread to any floppy disk inserted into the computer. A file virus inserts virus codes into program files… The virus then spreads to any program that accesses the infected file. A Trogan horse virus (named after the Greek myth) hides within or is designed to look like s legitimate program. Some viruses interrupt processing by freezing a computer system temporarily and th ...

Genetic Engenering -4

... and brains" (Bailey 1). On the other hand, the people who feel otherwise say, "Introducing genes into chromosomes is very much a hit or miss proposition. Scientists might achieve the results they intended once in twenty times, making the procedure far to risky to preform on a human embryo" (Nash 2). Many times scientist have proved that they do indeed have the power to duplicate an animal, plant and human body parts so that they are exactly identical to each other. For example, in May of 1998, scientists successfully cloned a calf u ...

Discovery

... “My Place”. The supplementary material that will be “Paperbark-tree” by Oodgeroo Noonuccal and Sarah’s Story from the National Inquiry. Two issues that are raised in “My Place” are the of self and the search for historical truth. Part of growing up involves the of self. This normally means finding out your family’s history. In “My Place”, Sally grows up feeling that there is a lot about her past that she doesn’t know. “the feeling that a very vital part of me was missing and that I’d never belong anywhere.” When s ...

Ibuprofen

... in this report I will attempt to explain the significance of that organism and why I chose to conduct tests on it. I then, with the information at my disposal, conjured a hypothesis which I would test. Using the materials at hand I, to the best of my ability tested my hypothesis. In conducting the tests I created graphs and tables of my work. At the conclusion of my experiment I came up with an answer that was almost unpredictable with the information that I was using. Although this was a crude experiment, I believe that I did gain a lot ...

Ocean Environment

... oceanographers collected seawater samples from all of the seas of the world at a variety of depths. When analyzed, the samples were found to have quite similar characteristics. These findings convinced many that a method of study was needed. The study of oceans was named oceanography. Density, salinity, and temperature are very important concepts in the study of oceanography. The salinity and temperature of the water influence its density, and the differences in density are the major factor in understanding the formation of currents an ...

Hawks

... killing, and consuming live animals has a characteristic similar to the hawk. Even though owls are not related to eagles, falcons, and vultures they have similar hunting habits and similar equipment for catching and killing - sharp, hooked beaks, and strong, sharp, curved toenails or talons. Owls are nocturnal for the most part and the others hunt during the day. Hawks evolved from raptors which also were birds of prey. Hawks evolved with eagles and falcons mainly but also with some other birds as well. Habitat and Biome Hawks live ...

Nuclear Legacy

... all contribute to the growing rate of "unwanted nuclear waste." The issue now is, how do we dispose of these nuclear wastes? Scientist have thought of several methods to dispose the nuclear by- products. They tried to chemically treat the waste and reuse it, but "that would cost a fortune". They thought of launching the waste into outer space but it too will cost a fortune. They tried to dump barrels filled with nuclear waste into the ocean but they started leaking. As you can see, there is a great need for a nuclear waste disposal site. ...
