Genome Sequencing
Number of words: 1656 | Number of pages: 7.... that have already had their genomes sequenced, a number are of particular importance. For example, Mycoplasma genitalium has a complete nucleotide sequence that is only 580,070 base pairs long, and as such, is believed to be the smallest genome of any free-living organism. Because of it's unique size, this genome presents a way of studying a minimal functional gene set. In addition, complete genome sequencing projects are currently being carried out on a number of microbial pathogens in an attempt to better understand them. The inference of molecular structures, in particular genome sequences, have direct practical consequ .....

INTRODUCTION
Theories explaining biological evolution have been bandied about since
the ancient Greeks, but it was not until the Enlightment of the 18th
century that widespread acceptance and development of this theory emerged.
In the mid 19th century english naturalist Charles Darwin - who has been
called the "father of evolution" - conceived of the most comprehensive
findings about organic evolution ever1. Today many of his principles still .....

in which they occur. For example the Tri-State Tornado of 1925 occured in the
Kansas, Oklahoma, and Texas States. This tornado was one of the largest
tornados recorded in history. It killed nearly 625 people. However, the
tornado which strikes closest to home has occured on what Canadians have come to
know as "BLACK FRIDAY".
The tornado of "Black Friday" touched down on July 31st, 1987 at 2:59 pm.
(See appendix #2 for the torndo path). (See appendix #'s 4&5 for maps locating
the disaster sights). 27 people were killed; 25 people died during the tornado
and 2 died later in the hospital. Hundreds .....

This is something being done, but water does travel and seep through ground so what is this act really doing. The clean water act is designed to protect ground water indirectly by protecting the quality of surface water. The standards for the surface water require sewage treatment , and discharge of industrial and municiple waste water into surface water. There is also the Comprehensive Environmental Response Compensation and Liability Act. (CERCLA) This creates liability and provisions for federal and state to seek reimbursement for resp .....

The Dung Beetle, What A Marvelous Creature.
Number of words: 643 | Number of pages: 3.... To realize why dung
beetles are so important, you must first know a few facts about them. Dung
beetles are named after their delight in rolling up dung. Dung beetles
utilize the dung of cows, horses, rabbits, deer, sheep, and many other
animals. How many of you think dung beetles actually eat manure? The
answer is yes. Dung beetles just love fresh dung. They shove the dung into
their mouths, squeeze it, and drink the juices that come streaming out! The
solid parts of the dung are squeezed for a second time in their jaws, and
then swallowed. If there are any eggs that flies might have laid inside the
dung, this squeezing ac .....

Earthquakes 2
Number of words: 526 | Number of pages: 2.... is a fault along which the two sides of the fracture move with respect to each other. An earthquake is caused by the sudden movement of the two sides of the fault.
Faults are divided into three main groups, depending on how they move. There are normal faults which occur in response to pulling or tension. There are thrust faults which are caused as a result of squeezing or compression. The third group is strike-slip faults which are caused as a result of either type of stress.
Some earthquakes tremendously effect the earth. No earthquake is exactly alike another so the effects vary depending on the part of the world the .....

Acting To Save Mother Earth
Number of words: 500 | Number of pages: 2.... The idea is to prevent unrecyclable materials from even entering the home. For instance, 60 of the 190 pounds of plastic-especially styrofoam-each American uses a year are thrown out as soon as packages are opened. Be kind to your planet by buying eggs, fast food, and other products in cardboard instead of styrofoam cartons. Buy beverages in glass or aluminum containers instead of plastic ones. Buy in bulk to reduce the amount of packaging, you will save money too. Finally, when you can, buy products whose packing shows the "recycled" logo. Materials that have been recycled once can be recycled again.
Wise management of haz .....

Evolution And Creation
Number of words: 601 | Number of pages: 3.... Darwin’s theory was
much more developed and better known. For example Darwin pointed
out that farmers would take certain qualities from two different plants
and mix them together and it would produce the desired plant. He
believed this happened in nature also and he called it “the survival of the
fittest” or “natural selection.”
There are a lot of different creation stories and they are the same
in that since but they are all different. The creation stories start at the
beginning of the world.
The creation myth I’ve chosen to wright about is based on what
native Americans bel .....

Bottle Rockets
Number of words: 452 | Number of pages: 2.... when we shot the rocket it flew at an angle. Also it shows why the launchers had stoppers, because if they didn’t the cork wasn’t strong enough to hold that pressure and would cause the rocket to begin flight prematurely. His second law can be used to describe how high and fast the rocket will go. If you wanted it to go really high and fast you would just pump more pressure into it then if you didn’t want it to go that high. You can determine how much force is needed by multiplying the mass by the acceleration.
Our rocket was fairly decent the only problems were that the wings were not completely stable. Our egg survi .....
