The Race To The Moon
.... of the Space Race, success was marked by headline-making, historical "firsts." Some of these firsts included the first satellite, the first robotic spacecraft to the Moon, the first man in space, the first woman in space, and the first spacewalk. To the chagrin of the United States, each of these early firsts were achieved by the Soviet Union, thus sparking the United States to not only catch up with the Soviets, but also to surpass them. (Alexander 37-39).
The Soviet Union stunned the world with the launch of the Sputnik "satellite" on October 4, 1957. Sputnik was a shiny basketball-size sphere containing radio transm .....

Environmentalism
.... trying? Maybe they are right in saying that we will never find the perfect mixture, but this negative attitude is part of the problem. Nothing will be accomplished unless we reject apathy and negativity.
One writer, T.H. Watkins, has criticized the idea of putting a “price tag” on the earth. He thinks that it is wrong to assign a value to out planet. How can we possibly give a monetary value to something that we can’t live without? Although this may be true, is it possible that this monetary value might give us a perspective on just how much the earth’s resources are worth to us? It is said that the “value of the biosph .....

Define A Concept : Astrology
.... forces between the planets involved in Astrology can be simplified into one word : gravity. The Sun has the greatest gravity and, therefore, the strongest affect on Astrology, followed by the Moon and the other planets.
Astrology can be best understood as a philosophy that helpsd to explain life, rather than simply a tool used to predict one’s future or fate. Each of the twelve Star Signs is a unique combination of one of the four Elements (Earth, Air, Fire, and Water) and one of the three Qualities (Cardinal, Fixed, and Mutable). Each of these Elements and Qualities demonstrate that we are all part of the environment and that t .....

The Beaver
.... the beaver can cut down large trees. It usually selects trees 5 to 20 cm (2 to 8 in) in diameter, but it can fell trees with diameters as large as 76 cm (30 in). Beavers have a pair of anal scent glands, called castors, that secrete a musklike substance called castoreum, probably for marking territories. The animals tend to be monogamous and may live 20 years or more. The female has one litter a year, usually of two to four young.
Beavers are social animals. In areas where food is abundant and the locality secluded, the number of families in a beaver community is rather large. The so-called beaver lodge is a unique structure. .....

Photosysthesis Experiment
.... in plants have different polarities, weights, and sizes. Although, it was hard to make a clear hypothesis as to how the pigments would travel due to my lack of knowledge of such pigments, I believed that the different pigments would indeed be divided. Furthermore that the lightest and most polar pigments would travel the most while the most non-polar and heaviest would be left in the bottom of the paper.
The second experiment in our lab consisted on observing electron transport in chloroplasts. This was done using an electron acceptor called DCPIP which is a dye is blue in its oxidized state is blue but after accepting ele .....

Cloning And Its Implications
.... such as makeup and shampoo. Creating life for the simple purpose of injecting a deadly disease in the body to find a cure is just? Another purpose of cloning may be for work labor. Should society create people to work for others like robots? People have different beliefs to answer such questions. A few people believe cloning can be helpful for those unexpected events resulting the death of a love one. If a brother or sister dies, should a person be allowed to create a new one that will be exactly the same? If this allowed, will the clone be exactly the same in sense of the personality and morals? Even clones must start out as bab .....

Genetic Engineering: A Leap In To The Future Or A Leap Towards Destruction
.... can be lifted.
The first step to understanding genetic engineering and embracing its possibilities for society is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process is dependant on the understanding of how individuals pass on characteristics to their offspring. Genetics achieved its first foothold on the secrets of nature's evolutionary process when an Austrian monk named Gregor Mendel developed the first "laws of heredity." Using these laws, scientists studied the characteristics of organisms for most of the next one hundred years following Mendel's discovery. These early .....

Air Pollution
.... pollutants into the atmosphere. The major pollutants from these source are nitrogen- oxides, sulfur-oxides, and carbon dioxide.
The rapid growth of population and industry, and the increased use of automobiles and airplanes has made air pollution a very serious and complicated problem. The air we know today and breathe has become so filled with pollutants that it can cause little health problems to fatal health problems such as lung cancer. Polluted air also harms most kinds of plants, animals, the materials that building are made up of, and fabrics of clothes, and decoration. In addition it causes damages by alter .....

Green Fluorescent Protein Purification
.... and physical characteristics to visualize various cellular activities.
One such application of GFP is to understand the role of a hormone, T3, in the translocation of thyroid hormone nuclear receptors (TRs).* In this project, GFP was fused to the human TR subtype b1 protein and the protein’s intracellular movement was visually tracked in live cells in the presence or absence of the T3 hormone. The prevalent hypothesis of this experiment was that T3 is essential in directing TR proteins to the nucleus of the cell where the proteins bind to DNA, regulating thyroid activity.
GFP was fused to the amino terminal because th .....

Planting Flowers

Because the early merchant ships that sailed from Europe were empty of goods on the trip over, their hulls were loaded with dirt so that they would float properly. When they arrived in America, the dirt was removed and left onshore. The seeds it contained then began to spread, bloom, produce more seed, and eventually spread" (6). Interesting enough, I have learned that another gift from the Europeans is the honeybee, which came to America in the 1600's (8).
Not all wildflowers tha .....

Hydroponic Gardening
.... growing methods is that a person can have a garden in small spaces such as an apartment. In addition a good source of natural sunlight is not required because the gardener will provide the plant's light requirements.
This form of growing plants is not only an interesting topic of study, but also a viable method of producing many species of plants in either a small hobbyist garden or a large industrial crop producing system.
Benefits of Hydroponics
There are a large number of benefits to be taken advantage of with the hydroponic method of growing. In general the plants are going to be healthier, grow faster, grow more den .....

Many problems come with the lagoons. North Carolina is one of the top hog producing states in the country. On June 21, 1995, North Carolina suffered the largest agricultural waste spill in its history: a 7.5-acre, 12-foot-deep lagoon leaked 25 million gallons of hog waste into the headwaters of the New River near Richlands. The waste from the 10,000-head operation, owned by Oceanview Farms, contaminated the water for several miles downstream, increasing the levels of nitrogen, phosphorus, and other nutrients. When nutrient levels increase dramatically in rivers and othe .....
