El Nino

... allowing the water to grow warm and expand. With the help of the National Oceanic and Atmospheric Administration's weather satellites, tracking shifting patterns of sea-surface temperatures can be made easier. Normally, a "pool" of warm water in the western Pacific waters exists. Under El Nino conditions, this "pool" drifts southeast towards the coast of South America. This is because, in a normal year, there is upwelling on the western South American coastline, and cold waters of the Pacific rise and push westward. However, during an E ...

Ehrlich's Population Bomb

... directly or indirectly linked to overpopulation. Ehrlich explains situation using various examples of how mass starvation is inevitable if population continues to increase the way it is currently. In third world countries their food supplies are becoming increasingly scarce because of their increasing populations. In these third world countries the rich-poor gap is increasing creating the potential for large parts of the population to starve. Paraphrasing Ehrlich's ideas in chapter can be explained as; there is only so many resources an ...

Nuclear Energy

... from atoms). An atomic bomb explosion shows just how powerful muclear energy really is. Such as the underwater explosion of an atomic bomb at Bikini during 1946. This powerful type of energy comes from many things such as atoms and subatomic particles; an atom is a tiny bit of matter that has very little weight. They are much too light to be weighed directly, but scientists have developed methods of determining these tiny weightd by using special labratory instruments. Hydrogen is the lightest of all atoms and carbon atoms weigh twelve ...

Creationism Vs. Evolution

... to us. We question the existence of God, or the creation of mankind rather than blindly accepting faith-filled beliefs we may received from our parents as children. Perhaps it is because we live in a nation filled with many peoples of different beliefs whose Gods are all so varied and different that it is difficult to fathom that they are all the same divine being. It is also plausible that we just have a desire to quench the thirst for knowledge that lies deep within ourselves. As for myself, I cannot believe in a being which cre ...

The Dung Beetle, What A Marvelous Creature.

... chosen this topic for a tribute speech, or maybe why I would even consider talking about it at all, but do you realize what an important role these beetles play all around the world. I remember several days when I was young that I would just go for a walk in my grandfather's pasture. I would enjoy the quiet walks, and sometimes try to scare the cows, but more often than not, I would end up stopping to watch dung beetles frantically work on a big cow pat. I remember how disgusting it appeared, but I was just fascinated at the concept of co ...

Bacteria 2

... Inside the capsule and the cell wall is the cell membrane. In aerobic bacteria, the reactions of cellular respiration take place on fingerlike infoldings of the cell membrane. Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen ...

Polymers

... product celluloid. The prime virtue of is a high strength-to-weight ratio. Industrial-strength surpass titanium in tensile strength. To add strength and improve flexibility, are sometimes fortified with short-fiber additives, mostly fiberglass. This is known as a polymer composite. One particular polymer has three times the strength of tempered steel and is being used in bullet proof vests. Another composite will be used to fasten together the sections proposed space stations. have also been used in cars, including the Chevrolet ...

Some human traits are behavioral, like manual dexterity, sexual orientation, hand-eye coordination, and schizophrenia, and some are not, like blood type (A, B, or O), race, or the hardness of tooth enamel. Some are disease traits: hemophilia, schizophrenia, cancer, color blindness. Some are politically and religiously charged: skin color, sex. Some traits are not politically and religiously charged: the hardness of the enamel on your teeth ...

Cloning: Background

... identical copies of the gene. Scientists used this technique to clone such amphibians as frogs and salamanders as early as the 1950s. In 1996, a group of Scottish scientists used the procedure to clone a sheep. This event marked the first time a mammal had been cloned in this way ("Clone"). The scientist who started cloning is Ian Wilmut (who led the group) (Recer). He cloned Dolly using the nucleus from the cell of its mother, and it had an exact genetic replica of its mother. This spurred arguments about cloning humans (Recer). After Wilmu ...

Household Waste!

... to do… "The Bleach!" I shouted aloud. And then -- it hit me, my mom's hand. "Never, Never, Never, use Bleach with ammonia. Infact don't mix any chemicals with one another." This is an excellent example of common mistakes people make when dealing with household chemicals/cleaners. In this assignment I will examine different cleaners commonly used in my house. I Ajax I go to the cupboard and find a can of the powder, Ajax. The can use to have a piece of tape to cover the top but now it has been lost; a potential problem. The can h ...

Lung Cancer

... of cells in the lung and spread in different ways. Small cell is limited to a section of the chest known as the hemithorax and regional lymph nodes (World Book, “”). Small cell usually exists early and spreads out abruptly (Virtual Hospital, 3/23/99). Non-small cell is first confined to the lung, then spreads throughout the chest (MSKCC, “”). Small cell spreads quickly (World Book, “”). In the United States 85 to 90 percent of all cases are related to smoking. Cigarette smoking is the main cause ...
