Cloning And Its Impact
Number of pages: 4 | Number of words: 1028.... and biochemical characteristics of an organism, of livestock is accomplished by bombarding embryos of livestock with genes that produce “super” livestock traits; however, this technique is not efficient because only five percent of the offspring express these “super” traits that would guarntee a more productive industry. Scientists can easily genetically alter adult cells; therefore, cloning from an adult cell would make it easier to alter the genetic material. The goal of transgenic livestock1 is to produce livestock with ideal characteristics for the agricultural indu .....

Aluminum
Number of pages: 2 | Number of words: 307.... Rocks
and minerals on the earth's crust. Because aluminum is not very strong and
is highly reactivate with Oxygen, water, acids, and bases it is compounded
with other metals and elements to from alloys for common uses. In Society
Aluminum Alloys are used in many ways because of it's light weight and
versatility. As more and more ways are discovered to strengthened Aluminum
with other elements more uses have also been discovered Aluminum is used in
aircrafts, Electrical Engineering, Windows, doors, buildings, packaging and
many other things. When aluminum is compounded with .....

Orangutans
Number of pages: 4 | Number of words: 1005.... coloured moustache, a pronounced
beard, and a diamond shaped face. Individuals can also be distinguished
chromosomally, biochemically, and by their cranial characteristics.
There is a great deal of individual variety in the orangutan. "Each
orang-utan had a distinct personality and in dealing with such highly
intelligent animals in captivity, the keeper's knowledge of the individual was
probably more important than the knowledge of the overall behaviour patterns "
(Markham, 1980). Orangutan males, however, appear to be totally intolerant of
one another, especially the .....

Acid Rain 2
Number of pages: 3 | Number of words: 695.... An indirect effect of acid rain on humans is that the toxic metals dissolved in the water are absorbed in fruits, vegetables and in the tissues of animals. Even though these toxic metals do not directly affect the animals, they have serious effects on humans when they are being eaten.
How did it happen? One of the main causes of acid rain is sulphur dioxide. Natural sources that let out this gas are volcanoes, sea spray , rotting vegetation and plankton. However, the burning of fossil fuels, such as coal and oil, are largely to be blamed for about half of the emiss .....

Cloning
Number of pages: 3 | Number of words: 683.... the "hasty legislation" that could possibly have negative long-term effects on the future of because 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 .....

The Problems With Acid Rain
Number of pages: 7 | Number of words: 1834.... to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early.
At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of the lakes were beginning to show signs of death. Fish were found dead along the banks .....

The Hale Bopp Comet
Number of pages: 3 | Number of words: 771.... Sagittarius. When I turned to M70, I saw a fuzzy
object in the same field, and almost immediately suspected a comet, since I had
been looking at M70 last month, and *knew* there wasn't any other objects
there."
Thomas Bopp explains his story like this, "On the night of July 22, 1995
some friends and I headed out into the desert for a dark of the moon observing
session. The site, which is west of Stanfield, AZ and a few mile south of
Interstate 8 is about 90 miles southwest from my home.
My friend Jim Stevens had brought his 17-1/2" Dobsonian. We started the
evening observing .....

Manatees
Number of pages: 7 | Number of words: 1737.... are closed by valves, so they can accomplish such feats as
flips and quick turns without losing any air. Manatees have no hind legs, but
instead one big, flat, spatula-like tail (Sentman 327). This feature made people
confuse manatees with mermaids for nearly four centuries (O'Shea 66).
Many biologists say that manatees possibly originated or evolved from
ungulates such as elephants and cows because of the way that they are built, and
certain features that they have in common. Like elephants, manatees have the
peculiar half-moon shaped fingernails, and thick, wrinkled s .....
