Exxon Valdez Oil Spill
Exxon Valdez Oil Spill
Exxon Valdez Oil Spill ABSTRACT In March of 1989, the Exxon Valdez oil tanker ran aground on Bligh Reef in Prince William Sound, Alaska. An eighteen foot wide hole was ripped into the hull, and 10.9 million gallons of crude oil spilled into the ocean. In the following weeks, many things transpired. This paper will discuss the cleanup, the damage, and the results of the biggest oil spill in United States history. On March 24, 1989, in Prince William Sound Alaska, the Exxon Valdez was moving South
Our Radiant Planet- Depletion of the Ozone Layer
Our Radiant Planet- Depletion of the Ozone Layer
Our Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that w

An Ecosystem's Disturbance by a Pollutant Paul Cordova L. Lehr December 11, 1995 Freedman defines a pollutant as the occurrence of toxic substances or energy in a larger quality then the ecological communities or particular species can tolerate without suffering measurable detriment (Freeman, 562). Although the effects of a pollutant on an organism vary depending on the dose and duration (how long administered). The impact can be one of sublethality to lethality, all dependent upon the factor

I am your usual plant cell. There are trillions of my kind on all plants, grass, and trees. My breed ranges from ten to a hundred micrometers. I am approximately twenty micrometers since I dwell in grass. My organelles stretch out to one to ten micrometers. If you are asking what I really do and how I live, I am going to answer them in this paper. First off, any cells requires a structure, metabolism, energy, nutrients, waste, and communication. I am more complex than most other cells. Bacteria

What makes plants grow Several people have puzzled over this question
What makes plants grow? Several people have puzzled over this question. There is no one single answer to this. Several factors contribute: Tropisms, environment, hormones, biological clocks, and even humans. We are trying to determine the effects of music on plants. It takes all these combined to have a plant that actually grows and a plant that is healthy and happy in its habitat. Hormones Hormones contribute greatly to the growth of plants. Hormones such as auxins, gibberellins, cytokinins, a

Cloning Twenty years ago, scientists said that cloning was completely impossible. But now, the science of cloning has come to realization. Imagine meeting an exact replica of somebody. They look alike, think alike, and even have the same genetic makeup. No, this isn't an episode of Star Trek, this is reality. This is the new world of cloning, and thanks to a 7-month-old sheep named Dolly, a new science has been born. As with every new science, there are those who believe in it, and those who op

The steam turns turbines that generate electricity. Hydroelectric power plants use the great force of rushing water from a dam or a waterfall to turn the turbines. The majority of thermal power plants burn fossil fuels because thermal power plants are cheaper to maintain and have to meet less of the governments requirements co

We all know that we must some day die; yet we continuously deny the forces at work inside ourselves, which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a safe haven and be rewarded for their lives with pleasures and fantasies of an unfathomable scale than to question the existence of a supposed omnipotent being.

The legalization of marijuana has been a long debated subject in America since the 1970's. The pro-marijuana society in America has made several claims as to how marijuana can help cure or lessen the effect of some diseases and that by legalizing the drug; the use of pot will actually decline. The fact of the matter is that marijuana is a drug that can be placed into a similar category as cocaine or heroine. Like these other drugs, pot (marijuana) smoking carries with it serious side effects th

Nutrition is the science that deals with food and how the body uses it. All living things need food to live. The food supplies energy, which people need to perform certain actions. Food also provides substances that the body needs to build and repair its tissues and to regulate its organs and organ systems. Food provides certain chemical substances needed in order for a person to maintain good health. These chemical substances are called nutrients. Nutrients can perform three important function

The outer membrane is what shapes the organelle to its egglike shape. The inner membrane which folds inward makes a set of shelves or cristae that allow the reactions of the mitochondria to take place. The more the mitochondria makes these reactions the more the inner membrane folds. This happens because the mitochondria now has more surface area connecti

Marijuana use among young Americans peaked in 1979 with a 60.4% of high school seniors admitting to at least trying the drug. Today it is said that 60 million Americans have used marijuana at one point or another in their life. That is approximately 1/3 of the nations population (Internet). If so many people have used it or are using it, is it really bad?

Cell division is controlled by DNA, but exact copies of the DNA must be given to the daughter cells (note use of “mother” and “daughter”). Bacteria reproduce by a simple process called binary fission. They have one chromosome which is attached to the cell membrane. This chromosome replicates, then the two copies

There are three characteristics that include: exoskeletons, segmented bodies, and jointed appendages. Another reason why insects are so successful is because most insects are small and therefore have ada
