Wolves are found all over the world, and on almost every major continent
of the earth. The following wolves are types of Gray Wolves (Canis lupus).
In eastern Europe the European Wolf (Canis lupus lupus) can be found

While the first is similar to many of the .....

The most common symptoms of depression include low self-esteem, loss of energy, or lack of interest in activities previously experienced as pleasurable.

George Wald, Nobel Prize-winning biologist and Harvard professor, said that most of the now being used commercially is in the agricultural sector. Plants are genetically engineered to be resistant to herbicides. Insects are being genetically engineered to attack crop predators. Wald noted that research is ongoing in growing agricultural products directly in the laboratory using genetically engineered bacteria.
Genetically engineered animals are being developed as living factories for the production of pharmaceuticals and as sources of organs for transplantation into humans in the United States and abroad. Fish are being gen .....

the south of the star, all the way down to El Nath, the
second brightest star (gamma Auriga) which is actually
shared with Taurus, and also known as beta Taurus.
Auriga's stars are fairly bright; five are second
magnitude or brighter. Alpha Auriga (Capella) is the sixth
brightness star, at a visual magnitude of 0.08. The star is
43.5 light years away, and is about ten times the size of
our Sun. Capella's visual magnitude is really the combined
brightness of the primary star and another star that
revolves every 104 days. This star is also known as
Menkalina. The star name derives from the Arabic name Al
Man .....

Genome Sequencing
<view this essay>.... genitalium finished 1995
Methanococcus jannaschii finished 1996
Synechocystis sp. finished 1996
Mycoplasma pneumoniae finished 1996
Saccharomyces cerevisiae finished 1997
Helicobacter pylori finished 1997
Escherichia coli finished 1997
Bacillus subtilis finished 1997
Archaeoglobus fulgidus finished 1997
The benefits of complete genome sequencing projects include a greater understanding of the organisms being sequenced and acknowledgment of the minimum complement of genes necessary for a free-living organism. Of the organisms that have already had their genomes sequenced, a number are of particular importance. For example, Mycoplasma .....

Aquaria In Relation To Science
<view this essay>.... Lastly a third type of bacteria converts nitrites to nitrates which are not harmful to fish but build up to toxic amounts generally within a few months. That is why 20% water changes every two weeks is essential to healthy fish keeping. It generally takes a tank 21 days to cycle. During those 21 days there are 3 days where the ammonia spikes to a large amount and 2 days later on when nitrites spike generally.
There are 2 types of filtration for fish tanks biological and mechanical. Biological is what I spoke about in the previous paragraph. Those bacteria grow best on objects besides gravel. That is why having plastic plants and other décor in the .....

Darwin’s Finches
<view this essay>.... speciation occurs when members of the same species are geographically separated and they adapt to their new habitats. They are reproductively isolated and soon they cannot interbreed, hence becoming a new species.
Species “A” Geographically Isolated
Permanent Isolation
- Bodies of water
- Mountain formation
- Volcanic activity
- Destruction by man
New Species
A good example of allopatric speciation is the differences between the common giraffe (Giraffa camelopardalis), and the reticulated giraffe (Giraffa cameloparadalis reticula). These two subspecies have formed on different sides of the Tana River in Kenya. They are phenotypically distinct, an .....

Through the computer people are now literally a few mouse clicks away from buying anything from cars to toothbrushes, clicks away from entering a chatroom and conversing with fellow “Netizens”, and few clicks away from databases, essays, articles, and multimedia presentations on any entity whatsoever.
For the same reasons that the World Wide Web is so valuable and popular, it is also bad and dangerous. You might be able to shop around for an airplane ticket and might decide to buy one over the internet, yet the minute you type in your credit card number you attract people in finding that number and using it without your consent. You mig .....
