Anthopleura Elegantissima
Words: 1229 / Pages: 5 .... the sea anemones, Francis dislodged them from the immense rocks to which they were attached. At the laboratory they were kept in glass bowls containing water from the sea and were fed periodically, exclusive of experimentation time. In case of any impairments from the collection process, the anemones were kept in these bowls for a few weeks before any of the experiments started. Only the most healthy anemones were used in the experiment. To free the anemones, Francis hit the bowl against a solid surface. To determine the sex of the anemones, they were severed and inspected for sex organs. When their sex organs are fully grown the female’s are .....

Dreams Rem
Words: 713 / Pages: 3 .... unknown regions within. He saw the dream as significantly analogous to a hysterical symptom. On the surface, they both appear meaningless and bizarre, but they become understandable when understood as
veiled expressions of an unconscious clash between competing motives.
Freud developed an elaborate theory and how the mind works while asleep. In 1953 sleep researchers led by Nathaniel Kleitman made the important discovery of rapid eye movement--or REM-- sleep. Curious about the long-standing observation that the eyeballs of sleeping subjects in both humans and animals periodically move during sleep, they connected laboratory subjects to equipment .....

Genetic Engineering 3
Words: 1929 / Pages: 8 .... With these discoveries comes many implications, In reviewing the literature genetic engineering needs to be banned because of the social, religious, ethical, and legal implications.
The first step to understanding genetic engineering is to know the start of its creation. Genetics achieved its first foothold on the secrets of nature's evolutionary process, when an Austrian Monk named Gregor Mendel developed the basics of how genetics work. Using this, scientist studied the characteristics of organisms for the next one hundred years following Mendel's discoveries. These early studies concluded that each organism has two sets of character det .....

El Nino La Nina
Words: 622 / Pages: 3 .... decreasing hurricanes for that year.
But when the warm waters brought on by El Nino recede, the cold waters of the Pacific Ocean move eastward and bring with it La Nina, the little girl. La Nina has a variety of different names such as El Viejo, anti-El Nino or simply "cold event". When the warmer Pacific water is pushed westward by the trade winds, that water flows toward Asia and makes room for the colder, deep sea water, to rise and flow to the Americas. Because cold water doesn't evaporate, there is a large reduction in the formation of storm clouds. The weather patterns of La Nina are basically an exact opposite of El Nino. Strong high pressu .....

The Problem Of Global Warming
Words: 457 / Pages: 2 .... in about five years.
Trees keep the air clean for the environment by taking the gases in and produces
oxygen out of it. By cutting down the trees we are allowing for more of the
carbon to be exposed into the atmosphere.
Another factor that most people would not consider in the raising of
global warming is the excrement of cows. Cows produces tons of carbon that does
not all get treated for, and is in the top five for highest amounts of carbon
produced per year. This is another factor that somehow has to be dealt with.
All of these causes of global warming have been know by scientists, it's
the effects we are seeing in today's climate now t .....

Depression
Words: 521 / Pages: 2 .... change as well. People with depression may start to sleep a lot more than they normally
would, but again they might also sleep much less than normal. A person with depression
doesn't realize and most of the time has no control whatsoever over these feelings. They
have no idea that what is wrong with them is that they have depression. They might put
the blame on some other stressful thing or even other people.
Changes in the level of energy a person has can be caused by depression. One
possible reason for this ties into their eating and sleeping habits. If a person starts to eat
less, or sleep less they will notice a drop in how much ener .....

The Origin Of Life On Earth
Words: 794 / Pages: 3 .... This ecosystem had a bulb, which contained an amount of water with hydrogen, nitrogen, and simple carbon compounds dissolved in them. These various elements were believed to either formed with the Earth or were picked up by the many meteoric collisions that immediately following the formation of our planet. The bulb had a heating unit under it to stimulate evaporation, then there was a smaller bulb that contained electrodes, simulating lightning and other static discharges, the evaporated water and gasses rose into this electrified bulb and were occasionally energized. The vapor then flowed into a condenser, and finally back into the simul .....

Fission Or Fusion
Words: 1273 / Pages: 5 .... no matter how large, cannot sustain a chain reaction because only the
uranium-235 is easily fissionable. The probability that a fission neutron with
an initial energy of about 1 MeV will induce fission is rather low, but can be
increased by a factor of hundreds when the neutron is slowed down through a
series of elastic collisions with light nuclei such as hydrogen, deuterium, or
carbon. This fact is the basis for the design of practical energy-producing
fission reactors.
In December 1942 at the University of Chicago, the Italian physicist
Enrico Fermi succeeded in producing the first nuclear chain reaction. This was
done with an arrangement of .....

Hail
Words: 1296 / Pages: 5 .... The biggest hailstone ever found was discovered in Coffeyville, a
small town in southeast Kansas. This hailstone weighed 1.671 pounds and
was 17.5 inches in circumference. The largest stone previously on record
was almost the same size. It was found in Potter, Nebraska on July 6, 1928.
The hailstone had a circumference of 17 inches and weighed 1.51 pounds
(Dennis 54).
Hail can be extremely dangerous. It can break windows, damage
roofs, dent cars, injure and even kill people! Crops are greatly affected.
Hail causes around two hundred million dollars in damage a year. That's a
lot of money. When the wind is blowing hailstones are at thei .....

Nuclear Power
Words: 356 / Pages: 2 .... and other pollutants into the
atmosphere.
The cleanest, cheapest, and least polluting power plant of the two types
is the hydroelectric power plant. The main reason most countries use
thermal versus the hydroelectric is because their countries don’t have
enough concentrated water to create enough energy to generate
electricity. (World Book vol. 14, 586)
Nuclear power plants generate only about eleven percent of the world’s
electricity. There are around 316 nuclear power plants in the world
that create 213,000 megawatts of electricity. (INFOPEDIA)
Radioactive, or nuclear, waste is the by-product of nuclear fission.
Fission .....
