... e of people to the overlying land. The water
is used for such activities as drinking, personal
hygiene, residential maintenance, and industrial

Gm Foods Genetic Modification
1,195 words
The British Government describes genetic
modification as the altering of the genetic
material in that organism in a way that does not
occur naturally or natural recombination or both.
Therefore genetic modification produces organisms
that would not occur in nature, unlike farming
methods such as selective breeding which could
occur naturally. To opposers of GM foods this
constitutes a fundamental difference. Genetic
modification is when DNA fragments are transferred
into different cells through ...

Role In The Nitrogen Cycle Nitrogen From The Atmosphere Tree
374 words
The nitrogen cycle is a complex biological cycle
involving the recycling of usable nitrogen. If
this cycle ceased to occur, all forms of life on
the planet would die. All life forms, including
humans, use nitrogen in compounds called amino
acids. These amino acids then act as building
blocks for proteins. Nitrogen, in fact, is the
most abundant element in the atmosphere. Most
organisms are unable to use this nitrogen from the
atmosphere and rely on the nitrogen in the soil.
The cycle consists of...

Red Blood Cells Vitamin B 12

Vitamin B 12 Vitamin B 12, scientifically known as
coba lamin, has specific chemical structure and
characteristics which qualify as a water-soluble
vitamin. However, unlike the other water-soluble
vitamins it is not disgorged quickly in the urine,
but accumulates in the liver, kidney and other
body tissues. Therefore, only after 5 or 6 years
of B 12 insufficient diet the vitamin deficiency
can be adequately distinguished. Vitamin B 12
serves as a methyl donor and cooperates with folic

utilised in defence against intracellular

chemical basis for biology has grown, we have
learned more about how molecules which constitute
life. Many scientists are beginning to understand
the connections between the physical and

them. As a result, we can now use these new
understandings of medicine against any dangerous
or unpleasant conditions. For example, depression
can be treated with drugs that can revive the
brain to its normal level....
