<view this essay>.... that "with offshore drilling comes substantial routine pollution in the forms of oil and gas." By routine, the EPA means "a near constant flow from oil rigs and derricks" (Sisskin). Nothing is ever done about the pollution, and until something is done about the oil being put into the sea, our oceans are at risk. So just how much oil is put in the oceans? According to a study conducted by the World Research Institute, "…between 3 and 6 million tons of oil are discharged into the oceans every year" (Gorman 48).

the focus of wood, there is the Western Canadian Boreal Forest which is a large

changes has had large and impacting effects on the construction industry.
Compared to eastern Canada, the southern boreal forest region of western Canada
has a relatively dry climate. Thus, drought effects are one of the major
concerns being addressed by researchers in this region. climate modellers have
predicted a large increase in temperature for this region, which could lead to
even drier conditions and enormous stresses on ve .....

American Alligator

All of the family Crocodylidae is endangered. However, the has undergone a dramatic population resurgence because of human protection. Restrictions are still in place on capturing alligators from the wild (Beck). Studies have shown that using hormones such as norethindrone can be used to feminize alligator embryos at the male producing temperature (Lance, 79). This could lead to a way to help alligators increase in numbers of both sexes as well as help other members of the family Crocodylidae. Alligators are important ecologically and are dependent on the spatial and temporal patterns of water fluctuations. Pa .....

Bacteria 2

Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aer .....

It dissolves in nitric or concentrated sulfuric acid but is resistant to
alkalies. Mercury melts at -39C, boils at about 357C,and has a gravity of 13.5.

sulfide.
Mercury has many uses and is a very important element. A major use of
mercury is in electrical equipment such as fluorescent lamps, and mercury
batteries. Mercury is used in thermometers because the change in volume for
each degree of rise or fall in temperature is the same. The use of mercury in
the thermometer .....

Mistakes People Make With Ster

digested food, reproducing, and getting rid of waste products.

muscular, digestive, and reproductive systems. In the circulatory system, blood
is pumped by the heart in a tube to the aorta, the head, and to other organs
then enters the ostia openings along the sides of the tube back to the heart.
The respiratory systems carries O2 to cells and takes away CO2 from cells
through branching out to call cells of body. The nervous system consists of a
brain receiving information from eyes, antennae, and controls the whole body and
