Biology / Sea Lamprey: A Great Lakes Invader
Sea Lamprey: A Great Lakes Invader
Sea lampreys are aquatic vertebrates native to the Atlantic Ocean. Sea lampreys resemble eels, but
unlike eels, they feed on large fish. They can live in both salt and fresh water. Sea lampreys, now
found in all the Great Lakes, attach to fish with a sucking disk and sharp teeth. Sea lampreys feed
on body fluids, often scarring and killing host fish.

Biology / Spinal Cord Regeneration
Spinal Cord Regeneration
Spinal cord injury can occur in many ways ranging from gunshot wounds, stab wounds and also bone displacement. These circumstances can lead to the death of neurons, and the demyelination of axons which causes some loss and damage to neurons. As Hudgins (1998) reports after a primary injury such as above, secondary injury occurs 30 minutes after and also that second...

Biology / Starfish
The asteroid, more commonly known as the starfish, or sea star, is an invertebrate that lives mainly in an ocianic environment. These unique and unusual creatures have a number of arms that protrude away from their spiny skinned bodies. The exact number of arms depends on the species; some have only three, and the most is 42. Most people commonly associate the starfish with haveing five arems. ...

Biology / Surface Currents
In the world's oceans, the surface currents move the oceans' surface water. This occurs in the Atlantic, Pacific and Indian Oceans. From a diagram of these surface currents, a number of conclusions can be made about the general patterns of the surface currents. One of these conclusions includes that they go clockwise in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere. The ...

Biology / The Birth Of Complex Cells
Today, all multicellular organism are composed of eukaryotic cells which are larger and
more complex than prokaryotes. These eukaryotic cells consist of organelles, such as
mitochondria and peroxisomes, which were once believed to have been prokaryotes. We
will find that these two organelles, which have triumphed through evolution, serve
important functions within cells.
We will begin wi...

Biology / The Ceolacanthe
The Coelacanth is a large fish that is closely related to today's lungfish. These two fishes are the lobe-finned fishes left on the earth. They're called lobe-finned fishes because of a muscular lobe they have at the base of each fin. The Coelacanth is believed to have been around since about 350 million years ago. The amazing thing about the Coelacanth is that modern ones are almost identical in ...

Biology / The Potao Famine: Gone But Not Forgotten
A hundred and fifty years ago in September, 1845, the Dublin local paper "Dublin Evening Post", reported a "disease in the potato crop". This turned out to be the potato blight which destroyed 40% of the crop that year and almost 100% the next year. The devatation was known as "The Great Hunger" and resulted in wide spread starvation and mass emigration to Britain and the Americas. As a result,...
