Carnivorous Plants

grows on dry gravelly hills. Like other green plants, carnivorous plants
contain the organic pigment chlorophyll. This pigment helps to mediate a
chemical process called photosynthesis. This converts light energy into the
chemical bond energy of carbohydrate which is utilized as cellular energy, plant
growth and development. Water, carbon dioxide, nutrients and minerals are also
needed for survival. In wetlands, where stagnate water contains acidic
compounds and chemicals from decaying organic matter many plants have a
difficult time obtaining necessary nutrients. It is in these nutrie .....

Chemistry

and the darting hail that prevents little boys and girls to attend school. I am
the vivid part of life. I shield protection for those below me from the sun's
intense heat. I am fed and drunk by those who go through hunger. As acid
contained in the human body, I digest food and clean out wastes. I am a
desperate hope for a cure, yet poison, slowly spreading in the air and along the
land. I am the colorful fireworks "sprocketed" across the dark sky when the
touch of two soft lips are gently pressed together. I am the warm tears
trickling slowly down a child's face when the thought of going to school all
alone crosses h .....

IS projects under development include the introduction of Individual Savings Accounts, with other likely future projects including telephone banking, credit cards, and auto/property insurance.
The fact that MSFS has entered the Financial Services Sector comparatively recently and with a established IS knowledge base from the parent company has meant that existing information systems have been well developed in terms of technology and are compliant with the latest industry regulations. Therefore there is little or .....

The General Effects Of Fire On
Words: 1481 - Pages: 6.... food supply or quality, or by altering interactions of species. Fire suppression has allowed forested areas to achieve a climax state which provides less forage for wildlife. While terrestrial wildlife is benefited by fire, aquatic ecosystems are negatively impacted by large fires through the increase in sediment flow. Fire is essential in maintaining biological diversity in the Northern Rocky Mountain forests.
NEGATIVE EFFECTS - AQUATIC ECOSYSTEMS
Contrary to the beneficial impacts of fire on terrestrial wildlife, aquatic ecosystems are negatively affected, such as the decrease in fish populations by fire. In the North Fork Shoshon .....

The Shrew
Words: 531 - Pages: 2.... burrow is a small underground number of shallow tunnles under flat
stones or logs. Burrows found in east Texas were about 2.5 cm round, from
25 cm to 1.5 m long, and not more than 20 cm below the surface. Each burrow
has a large area at the end for the nest which was composed of shredded
grass. These nests were used for young or as a resting place for groups of
adult shrews.
Compared to most types of shrews, the least shrew is sociable, and
several may be kept together in captivity without conflict. They sleep
together and help eachother to some degree in digging tunnels and finding
food. One nest found in December in Texas contai .....

be caused by another, less serious conditions. Some symptoms include enlarged lymph glands,
tiredness, fever, loss of weight, diarrhea, and night sweats.
AIDS is caused by two viruses that belong to a group called retroviruses. The virus

that produces AIDS. This such virus became known as HIV-2 and occurs mainly just in Africa.
The virus,HIV-1 is spread throughout the world . HIV
infects certain white blood cells, including T-helper cells and macrophages, that play key roles in
the functioning of the human immune system. T .....

Nuclear Energy
Words: 1733 - Pages: 7.... highly radioactive. The isotope
catches the fast moving neutrons created by the splitting atoms, it repels the
slower moving protons and electrons, then gathers the neutrons and pulls them
inward. While all these atoms are flying about they smash together then split
many of many times, this is when the reactor grabs and pulls in the frictional
energy to be processed into electrical watts.
This usually causes heat or thermal energy, this must be removed by some
kind of a coolant. Most power plants use water or another type of liquid based
formula. these coolants are always base related, never acidic. Very few use
gas related coolants i .....

Big Bang
Words: 1243 - Pages: 5.... from each other ever since. Today the universe is still expanding, as astronomers have observed. The Steady State model says that the universe does not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler effect wh .....

How far will we let biotechnological discovery take us? What

The earliest and maybe simplest use of genetic manipulation
was in the selection of the sex of an unborn child. In Vitro
Fertilization(IVF - A procedure in which a woman’s eggs are
removed from her body, fertilized outside using sperm from her
husband or another donor, and then transferred back to her body.)
