Genetic Engineering -
Number of pages: 4 | Number of words: 980.... way. Our goal should be to find areas where it is needed rather than try to misuse it for personal gain. Genetic engineering can provide medical benefits to humans, but limits have to be set.
Our body contains one hundred trillion cells, inside most cells is a nucleus that contains a complete set of the body’s blueprints. Those blueprints are twisted into forty-six packets called chromosomes. Unravel a chromosome, and you get the long, thread-like molecule called DNA. Within the DNA are the blueprints, called genes, for which make proteins. The DNA molecule .....

The Platypus
Number of pages: 4 | Number of words: 961.... There are two different types of burrows, dwelling burrows, and nesting burrows. The nesting burrows are used for rearing young, and the other dwelling burrow is used by both sexes as a place to rest, sleep and eat. Burrows have a problem with maintaining a flow of air through them. If a platypus stays in a burrow for too long it will begin to use up its supply of oxygen. The nesting burrow has an entrance above water level to increase oxygen supply, whereas the dwelling burrows are located below water level.

Science Experiment On Odor Changes Of Various Chemicals
Number of pages: 7 | Number of words: 1820.... to the experiment. The chemicals included vinegar, ethyl alcohol, sulfuric acid, salicylic acid, and methyl alcohol.
RESEARCH OF THE PROBLEM
To start my project, I researched vinegar. Vinegar is a sour liquid with a pungent odor, containing acetic acid, and is made by fermenting dilute alcoholic liquids such as cider, wine, or other fruit juice. Vinegar is used as a condiment, preservative, and in certain medicines (2: 1214).
Ethyl Alcohol is also used in medicines. The formula for this is C2H5OH. It is a colorless liquid with mild characteristic odor. Also known as etha .....

Nuclear Power
Number of pages: 6 | Number of words: 1403.... is because their countries don't have enough concentrated water to create enough energy to generate electricity. (World Book vol. 14, 586)
plants generate only about eleven percent of the world's electricity. There are around 316 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. (General Information) When a free neutron splits a nucleus, energy is released along with free neutrons, fission fragmen .....

Mechanical Energy
Number of pages: 2 | Number of words: 506.... substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening.
The movement of the windsurfer has a different explanation. The windsurfer is propelled along by a sail which collects from the winds that sweep along the water. This energy has been produced by the sun which warms the earth's surface and sets the air above in motion. The sun's heat comes to the .....

Clean Coal Technologies
Number of pages: 6 | Number of words: 1551.... nearly 15,000 Btu's per pound (British Thermal Unit, is the amount of heat needed to raise the temperature of the pound of water one degree Fahrenheit) (Bartow 1) The second type of coal is Bituminous or soft coal. It's the most plentiful type of coal in the States, and is mainly found in the eastern and middle part of the North American continent. Bituminous coal is primary used to generate electricity, and has a carbon content of 45 to 86 percent and a heat value of 10,500 to 15,000 Btu's. Sub-bituminous coal rank just below bituminous coal with 35 to 45 percent carbon c .....

Pheromones
Number of pages: 2 | Number of words: 481.... Pheromones are produced by the body
and usually do not smell at all pleasant, whereas perfumes are either
synthesized or extracted from natural products and are employed because of their
pleasant smell.
Scientific research suggests that there are human pheromones for both
the male and the female. Females have a better developed sense of smell and
testing indicates that they are more responsive to male pheromones than the
reverse.
Research over the years has found that the male pheromones belong to a
class of compounds called steroids, in particular derivatives of and .....

To What Extent Does Acid Precipitation Affect Annelids?
Number of pages: 3 | Number of words: 641.... fuels, mainly in power satations and road transport. (Kucera, (1973) The Challenge of Ecology, The Mosby Company.) Tremendous quantities of this nitric acid and sulfuric acid mix are reflected in the lowering of the acidity of rain.
Earthworms (Annelids) are a species of worm which are many segmented. They live in damp soil, usually forming intricate tunnels beneath the surface. Their bodies are lond and cylindrical, and have "bluntly tapered ends and are somewhat depressed posteriorly." (Storer, et. al, (1972) General Zoology 5th ed., McGraw Hill Books.) As earthworms burr .....
