Hydrologic Cycle
<view this essay>.... off. The amount of precipitation that infiltrates, versus the amount that flows across the surface, varies depending on factors such as the amount of water already in the soil, soil composition, vegetation cover and degree of slope. Surface runoff eventually reaches a stream or other surface water body where it is again evaporated into the atmosphere. Infiltration, however, moves under the force of gravity through the soil. If soils are dry, water is absorbed by the soil until it is thoroughly wetted. Then excess infiltration begins to move slowly downward to the water table. Once it reaches the water table, it is called ground water. Ground water continues .....

the anesthetic. NO is not soluble in water. It is a clear gas. When NO is
exposed to air, it mixes with oxygen, yielding nitrogen IV dioxide, a brown gas
which is soluble in water. These are just a few of the chemical properties of
nitric oxide. With the total life expectancy of nitric oxide being from six to
ten seconds, it is not surprising that it has not been until recently that it
was discovered in the body. The compound is quickly converted into nitrates and
nitrites by oxygen and water. Yet even its short-lived life, it has found many
functions within the body. Nitric oxide enables white blood cells to kill tumor
cells and bacteria, a .....

New High-speed Connections Will Change How We Work And Play
<view this essay>.... everyone connects to the Internet using an analog modem. To get online, we boot up our PC’s, and using our telephone line, dial in to our Internet Service Provider.
Because telephone technology is much older than the Internet, there have been limitations to how fast data can travel over existing copper telephone lines. Using an analog modem, data is translated from its digital form to an analog signal, to travel over the telephone lines. Once it gets to its destination, the data is converted back into its digital form. Line noise is a result of data being transmitted as an analog signal. The FCC imposed limitations, decades ago, to minimize the .....

Next, Oprah spoke with a man who had lost his nose to frostbite but was able to grow an entirely new nose from scratch just by attaching the forming skin cells and DNA to his forehead and sewing the newly grown nose back to his face. This brought to mind an article I had recently read about the dangers of scientific some advancements. Coincidentally, the article was called, “Brave New Worlds”. It stated that “Developments in the field of genetics offer the possibility of bringing all life processes under control. We must step carefully into this vast new field of science with the understanding that putting a patent on the mela .....

LSD’s study was revived in 1943, when research indicated it could potentially be used as treatment for schizophrenia, due to its similarity in structure to Nicatamide, a chemical found in the human brain, which directly affects the experiences of a Schizophrenic (DEA,1). On April 16, 1943, while Dr. Hofmann was measuring a fresh quantity of LSD, he accidentally dosed himself and was overcome with confusion. He was then obligated to leave work due to “a sensation of mild dizziness” and “extreme activity of .....

Photosynthesis
<view this essay>.... pigment chlorophyll makes the change of
carbon dioxide and water to glucose and oxygen possible. It was Jan Ingenhouz
with Jean Senebier in Geneva that founded the basic gist of the theory of
photosynthesis in plants.
My experiment involves testing different brands of plant food on plants
to see what brand of plant food makes the plant grow the tallest. I will test
three types of plant food on three sets of plants and one set with no food. I
will water the plants all the same amount and let all the plants get the same
amount of sun, then measure the height of all the plants at the end of six weeks
and record the data.
The first step of photosynthesis is .....
