... organism and to
furnish all descendants with protein-synthesis and hence the growth and
development of the organism. So all living things on plant Earth contains the
genetic material DNA and the structure of a DNA molecule or combination of DNA
molecules determines the shape, form, and function of the offspring.
2)The term "genetic technology"(or genetic engineering) is the modification of
the genetic properties of an organism by the use of recombinant DNA technology.
By using this technology it is possible to alert characteristics of living
organisms in specific ways. The chemical languages of DNA ...

Deforestation
Number of Words: 1418 / Number of Pages: 6
... to 58% of the forests are found in
the temperate/boreal regions and 42% in the tropics. For about a millennium,
people have benefited from the forests. Forest products range from simple
fuelwood and building poles to sophisticated natural medicines, and from high-
tech wood based manufactures to paper products. Environmental benefits include
water flow control, soil conservation, and atmospheric influences. Brazil's
Amozonia contains half of the world's tropical rain forests. The forests cover a
region 10 times the size of Texas. Only about 10% of Brazil's rain forests have
been cut to date, but cutt ...

Ebola Virus 3
Number of Words: 476 / Number of Pages: 2
... there were no reported cases of the Ebola virus. Without warning, the Ebola appears and sweeps through Sudan, once more. This time there were only thirty four cases, but took the lives of twenty two patients. All of the victims of Ebola probably ask the same questions, “ God, what did I do to deserve this? ” The doctors still did not find the cause of the Ebola virus. I wonder how are the doctors suppose to explain to the patient’s condition. It must be pretty hard. One such reply would be, “ We do not know the cause yet. But you only have a matter of hours to live. Sorry ...

Then there are three very weird people in the room that are always in the middle
of the room doing the Waltz. They do this some how by themselves and they to
are always winking. They are sometimes on the first floor and sometimes on the
second floor. (Mars, Jupiter, and Saturn) There is also one guy dressed in a
white polyester leisure suit, gold chains, and rings dancing to "Stayin' Alive."
(comet) It seems as though everyone in the universe hears their own music. He
is only in the room for a little bit; he makes his way across the room then
leaves, he must get tired r ...

... as this illness. Here is a statement from before the discovery of the illness:
In 1799, a boy about eleven years of age was found naked in the woods of
Averyron, France. He was dirty, covered with sores, mute, and behaved like
A wild animal. Jean Itard, the physician of the new institution for deaf-mutes,
Was given charge of the abandoned child. From Itard’s description, Victor
Showed many features of autism—he did not look at people and never
Played with the toys, but showed remarkable memory in recalling the position
Of objects in his room and resisted any change of these objects. (Palu ...

Cyclones
Number of Words: 547 / Number of Pages: 2
... Cyclone Tracy hit the coastal city of Darwin on Christmas Day 1974. Although people had warning on New Year's Day about Cyclone Tracy, they were busy preparing for Christmas and thought that the cyclone would pass away just like Cyclone Selma had done three weeks before. Cyclone Tracy came roaring down the Arafura Sea (where most the develop in that area) and was on track to bypass Darwin but changed direction 900 past Melville Island and straight towards the city. At this time most people were asleep or partying. By 1:00 AM, the city of Darwin felt the full effect of the cyclone. Some peo ...

Cloning

... of the bad wording going into some of the laws. Many are afraid that the rich and famous might take advantage of the opportunity to generate copies of themselves. Nash points out that even though the possibility is there, the people who could grow full human clones "aren't going to be doing it."
Nash recognizes that by individual cells for the purpose of eliminating life-threatening diseases many people could be benefited. Doctors could obtain healthy cells from a part of the human body and grow them in dishes to be used to fight against that particular disease. Nash sites that this co ...

On Darwin's Theory Of Natural Selection
Number of Words: 655 / Number of Pages: 3
... evolution.
Darwin's findings begin in the Galapagos Islands where he noticed a wide
array of finches whose beaks were different sizes. He believed that the
physical conditions on the island did not affect the birds' beaks, but it was
the birds' feeding habits. For instance, the birds with the large, powerful
beaks ate large seeds, while the birds with the small or fine beaks, ate small
seeds or insects. He theorized that each bird was suited to its surroundings
and was adapted to its environment, thus the birds best suited to the
environment prevailed and reproduced, leaving those who did not ...

Capacitors
Number of Words: 504 / Number of Pages: 2
... values of capacitance required do not have to be large, but the energy loss in the dielectric must be very small. Some applications for these are in radio- frequency circuits and low- frequency measuring circuits where great precision is required. Another type of capacitor uses castor or mineral oil for the dielectric. Oil insulated are used in applications where larger values of the capacitance are required. also use solid dielectrics such as films of synthetic materials, paper, glass, and mica. Mica has excellent properties as a dielectric. It is both high in its dielectric constant and i ...

Acid Rain 6
Number of Words: 906 / Number of Pages: 4
... the nutrients in the soils are washed away making it hard for some plants to grow. The presence of nitrogen oxide and nitric oxide also can force trees to grow even though they do not have the necessary nutrients. The trees are sometimes forced to grow during late autumn when it is actually the time for them to prepare for severe winter weather.
One of the direct effects of acid rain is on lakes and the whole aquatic ecosystems. There are several ways the acidic chemicals can enter the lakes. Some exists as dry particles in the air while others enter the lakes as wet particles such as rain, sn ...
