... stories about adorable animals that do something amazing or need our help. There are also stories about animals that are used in good and bad experiments. When you hear about the treatment of some animals for research, you feel like forgetting about research. One such story was in 1988, three gray whales got stuck in freezing waters in Alaska, the whales were at risk of drowning because the holes in the ice that they were using to breathe were slowly freezing over. a large rescue was put together that ended up involving the National Guard and the U.S. and Soviet governments to get the whales free (Luke 87). Another story is of a mother cat that risked burning ...

... seems to bother the person. Heroin is the most addictive narcotic. Of all narcotic addicts, 90-95% use heroin. In the United Stated alone, there are between 500,000- 750,000 heroin addicts. Heroin is often mixed with cheaper substances, so that the dealer can make a larger profit. Since addicts don't know about the purity of a substance, many die because of overdoses. In an overdose of heroin, the lungs stop functioning, and the person dies from lack of air. There can be other effects of heroin addiction, one is that people who have illnesses may have them go untreated because the heroin has masked the pain. Another is that peoples veins collapse, from havin ...

... balance is disrupted and there will be less available for the native species. Once the new species has found its ecological niche however, balance begins to restore itself. When the biodiversity in the ecosystem is reduced, the ability of the ecosystem to grow, or the biotic potential, is as well reduced. More species residing in an ecosystem which depend on each other allows for a greater chance of survival and perpetuation. This may occur for several reasons, for example a bee and a flower. The bee requires the pollen of the flower to make its honey. However, while gathering the pollen from the flowers, it transfers some of the pollen to female flowers, a ...

... 8). Even babies can become depressed if they’re neglected. Many young people that suffer from depression turn to suicide. 5,000 young people take their lives each year (Stewart 9). The rate of suicide dealing with teenagers, 15-19, has tripled in the past 30 years (Salmans 40). Suicide is the 2nd leading cause of death among older teens (Stewart 9). Depression isn’t the only reason for suicide though. Depression has many effects on a person, both physically and mentally. Restlessness, irritability, frequent crying, and change in behavior are all common signs (Kist 26). Chronic aches and pains, such as headaches or stomachaches and other digestive problems th ...

... they spent three billion over the next several years on the clean up. During the cleanup, Exxon employed the assistance of 12,000 people and 1,385 ships and planes. They recovered a little over 2.6 million gallons of oil from Prince William Sound over the cleanup period. The estimated number of dead birds was 33,126 along with 138 eagles and 980 otters. Usually, when we are thinking of oil pollution what comes to mind is maybe a disastrous oil tanker spill somewhere in an ocean that ends up killing thousand upon thousands of wildlife living in that region. One example of this is the Exxon Valdez which spilled oil from its tanker into Alaskan waters and dumped ...

... which can then be used to turn electric generators there must be another method. The concentrated beams of sunlight are collected in a device called a solar furnace, which acts on the same principles as a large magnifying glass. The solar furnace takes the sunlight from a large area and by the use of lenses and mirrors can focus the light into a very small area. Very elaborate solar furnaces have machines that angle the mirrors and lenses to the sun all day. This system can provide sizeable amounts of electricity and create extremely high temperatures of over 6000 degrees Fahrenheit. Solar energy generators are very clean, little waste is emitted from the ge ...

... cost about 57 million dollars to construct. About nineteen major contractors worked on this plant and were supervised by the Engineering firm of James F. Macharen Limited. Although it is the newest plant, it had it’s disasters. Their intake value exploded twice between 1980 and 1995 because of the extreme pressure and Wight of the water. these incidents cause a shutdown of the plant until they could repair it. Production The Frank J. Horgan Filtration Plant needs only one row materials to operate, which is water. The plant is right next to lake Ontario, collecting water to purify. The water enters the plant by means of two 114 and four 182 million litres per ...

... collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. The star manages to av ...

... as a feeling of intense happiness and well being. Most users take the pills orally, often with alcohol. The most common way to get the barbiturates is in tablet form. Other ways to get barbiturates include ampoules, syrup, or capsules. For injection, which is rarely used because of its risk factor, capsules are opened and the powder is added to water. However, this can cause damage to the veins. Barbiturates come in different types such as Soneryl, Nembutal, Amytal, and Tuinal. Small doses relax the user, depressing the nervous system while the effects last up to 8 hours depending on the dosage. Large doses can cause loss of co-ordination, slurred spe ...

... atomic masses). Mendeleyev wrote a two-volume book called Principles of chemistry (1868-1870), which later became a classic. These books included an improved version of the periodic table. Sir Joseph Thomson, another important person in the development of the atomic theory, was born in 1906. Thomson won the Nobel Prize in physics (1906) for his work in the conduction of electricty through gases. He discovered the electron by using cathode rays. An electron is the smallest particle of an atom, the charge on an electron is negative. Ernest Rutherford, who was born in 1871 identified the three main components of radioactivity: alpha, beta, and gamma part ...
