UFOs
2685 Words - 10 Pages

.... the next pages the theory that UFOs are real because of evidence the government has covered up, the number of sightings, and the uncountable number of abductions, will become a reality. The first reason that is going to be addressed, is the secrecy and Government coverup of UFOs. "National Security Agency, or NSA, an acronym often assumed by insiders to mean 'NEVER SAY ANYTHING' , (Stacey 40) " has been blamed for millions of UFO governmental cover-ups around the nation. "Our problem is with government secrecy, because it widens the gap between citizens and the government, making it much more difficult to participate in the democratic process (Stacey 40)," says Steven Aft ....


Little Green Men Or Just Little Microscopic Organisms?

.... meteorites that were about 2 to 8 millimeters long and found trace elements of a big mumbo jumbo word— polycyclic aromatic hydrocarbons. That pretty much means that there once was a warmer climate and maybe even lakes or oceans. Life on Mars is now a real idea. The climate of Mars about 3.8 billion years ago was much similar to the young Earth. Microbes and bacteria probably sprouted everywhere in the warm and wet climate. Although now we only see a cold red planet, which was probably due to a collision of an astroid that would have set back the evolution process of Mars, causing it to be a harsh planet. A Viking spacecraft which landed on Mars in 1976 found that ....


Plate Tectonics

.... and called the new theory "Sea-floor Spreading". Among the seafloor features that supported the sea-floor spreading hypothesis were: mid-oceanic ridges, deep sea trenches, island arcs, geomagnetic patterns, and fault patterns. Mid-Oceanic Ridges The mid-oceanic ridges rise 3000 meters from the ocean floor and are more than 2000 kilometers wide surpassing the Himalayas in size. The mapping of the seafloor also revealed that these huge underwater mountain ranges have a deep trench which bisects the length of the ridges and in places is more than 2000 meters deep. Research into the heat flow from the ocean floor during the early 1960s revealed that the greatest h ....


Evolution From A Molecular Perspective
3032 Words - 12 Pages

.... for humans, however. What if the information stored in our genes was available to the public? Would insurance companies and employers base their selections on these traits? Also, with the total knowledge of every sequence of every amino acid chain in a person's genome, couldn't a laboratory perceivably reconstruct an exact copy of, or clone, that person? These are all issues that will have to be dealt with in the near future, but for now we need only concern ourselves with the objective observation of these proteins in our attempt to explain our ever mysterious origin. As humans, we are the first creatures to question exactly where we came from and how we got here. ....

4541 Words - 17 Pages

.... less than fun. I quickly sank to the bottom into a new world, with unfamiliar dangers. I really wasn't ready for this experience. I was disorientated, causing me to panic, which shortened the length of my dive, not to mention my air supply. Let's just say I would not do that again. To start exploring the underwater world, one must first master a few skills. Certification is the first step of learning to dive. From qualified professionals one must learn how to use the equipment, safety precautions, and the best places to dive. This paper is designed to help give a general understanding of the sport and the importance that physics plays in it. Self- contained Underwat ....


The Periodic Table

.... change gradually through a certain number of elements, called a "period" of elements. Then they repeat, through the next period. To express this, Mendeleev stated the periodic law: The properties of the elements are periodic functions of the atomic weights. provides an easy way to show the division of the elements into acid-forming and base-forming types. Those on the left are base-forming; those on the right are acid-forming. Those in between can be either. They have so-called amphoteric oxides and hydroxides that can act like acids or bases. 's arrangement also divides the elements into metallic and nonmetallic kinds. A distinction is usually made between most pure m ....


Afluenza

.... affluenza I hope to shed insight those possibilities. There is a disease that is sweeping the U.S. at an alarming pace. It is called affluenza it is very contagious and growing at frightening rates. In 1997, an amazing 1.1 million debt plagued spenders filed for personal bankruptcy that was a 28.6% increase from '96.

.... the size of the follicle increases until an egg is released. The corpus luteum formed in the follicle secretes progesterone that prepares the lining of the uterus for pregnancy.
