Pesticides
.... like Raid, and ant traps.
Pesticides are dangerous to our environment, but in most cases they help more than they hurt. For example, it is estimated that the food supply would reduce by forty to fifty percent without the use of pesticides on our crops. The FDA, EPA, and the Department of Agriculture try to ensure that the use of pesticides is necessary to the extent in which they actually are used by performing studies and proposing bills and laws to Congress. There is no dispute that pesticides are .....

Can Intelligence Be Measured
.... same in every school. The actual environment that they are taking the test in could be different and affect different individuals in different ways. A person could not be feeling good on the certain day of the test and this certainly affects the outcome of the test. Well if you do badly on it you will just be thought of as stupid and it is not really you're own fault. Normal standardized test get predictable results around the academic standpoint of intelligence, but should not be held to tell weat .....

Animal Uses
.... conducting animal tests to see if there product are irritating (664). These experiments were tested on rabbits only because they have no tear glands to wipe away any foreign objects on the eye. The animal would be strapped down and the "product" would be dropped into the eyes. After irritation came pain, after pain came ulceration and bleeding, blindness would follow. Other tests would include "forcing hair dye or face powder into a dog or rat through a stomach tube until its internal organs rupture. .....

Anthopleura Elegantissima
.... bowls containing water from the sea and were fed periodically, exclusive of experimentation time. In case of any impairments from the collection process, the anemones were kept in these bowls for a few weeks before any of the experiments started. Only the most healthy anemones were used in the experiment. To free the anemones, Francis hit the bowl against a solid surface. To determine the sex of the anemones, they were severed and inspected for sex organs. When their sex organs are fully grown the .....

The Beginning Of The Universe
.... 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 found that can prove the Big Bang model is more reasonable than the Steady State model. Firs .....

The Problems With Acid Rain
.... great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early.
At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were no .....

Genetic Cloning And Frankenstein
.... exhortation for today’s technological advances in genetic cloning.
Mary Shelly’s “Frankenstein” provides a clear distinction between the theoretical grandeur of man’s ability to scientifically author life and the stark reality, which it encompasses. Mary prophetically illustrates some of the potential hazards of breaking through the barrier that separates man from God (Bloom 611). Her insight allows the reader to trace these repercussions through Victor Frankenstein, the monster, and eventu .....

Research And Patterns Of Thinking
.... decided to visit the few I singled out which greatly helped me choose this for my education. Next I had to perform and even harder task, choosing a major. It's very difficult to decide what you want to do with the rest of your life in just a short time. I had the plans of working in the woods, so I talked with some friends who work with wildlife conservation and they told me parks and recreation was the way to go. After this strenuous research, I was very glad to get it over with.
Another time I used .....

Diffraction And The Debye-Scherrer Camera
.... = Acos(wt + f)
where x is the position along the x axis
A is the amplitude or in other words the maximum possible
displacement
w is the angular frequency and f is the phase constant
or phase angle and has units of radians per second.
The phase constant determines the position of the particle at time t = 0. The quantity (wt+ f) is called the phase. The above function x repeats itself whenever wt = n2p where n is an integer. The period T of the motion is the time it takes for the mot .....

Tomatoes
.... weeds (nightshades, jimson weed). It may have been this association with the nightshades which originally led people to believe the tomato to be poisionous. It was therefore fortunate that Miller changed the species name to esculentum which roughly means "edible".
The common cultivated tomato belongs to the genus Lycopersicon. This genus exhibits a vast reservoir of genetic variability which remains largely underexploited. Some disease resistance, which is now a part of most commercially available cu .....

Flooding

There were those who believed people should not be allowed to rebuild in hazardous areas and those who would not forbid them to build as long as they did not ask for recompense when they got into trouble. One group has felt property owners s .....

Water Pollution
.... 5,550,000 plastic, metal, and glass containers into the ocean in a single day.2
The most harmful of these is plastic. Sea mammals such as birds and dolphins often get tangled in the plastic six-pack rings, fishing lines, and net that humans discard into the ocean waters. Once entangled, they are unable to free themselves which can cause deep cuts, starvation, and drowning. Many ocean mammals have died as a result of ingesting these plastic items. In 1985, a sperm whale beached itself on a New Jer .....

Advanced Green Builder Demonstration House

Large metallic cisterns, which store rainwater, are placed near the front of the house in such a way that it creates an entranceway into the house that lets visitors know the occupants concern for the environment. Along side the huge silver cisterns is the waste water cleaning system that was designed to be as aesthetically pleasing as possible through the use of indigenous plan .....

The Effects Of Hurricane Gilbert
.... Atmospheric conditions were some of thefactors that contributed to Hurricane Gilbert's intensity. Hurricane Gilbert had extremely powerful winds that reached 160 knots which is about 175 mph and gusts up to 121 mph (Stengel 18). At 10, 000 feet, Gilbert's Counter clockwise winds reached up to 200 miles per hour, and at ground level the winds were around 175 mph(Stengel 17). With winds that strong, almost nothing could stop that storm. When the winds began to spread out over a large area, they stirred the .....

Nuclear Power
.... versus the hydroelectric is because their countries don't have enough concentrated water to create enough energy to generate electricity. (World Book vol. 14, 586)
Nuclear power plants generate only about eleven percent of the world's electricity. There are around 316 nuclear power plants in the world that create 213,000 megawatts of electricity. (INFOPEDIA) Radioactive, or nuclear, waste is the by-product of nuclear fission. Fission occurs when atoms' nucleus' split and cause a nuclear reaction. ( .....
