- Concentration And Reaction Rate
Concentration and Reaction Rate
How concentration affects reaction rate.
The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitat...
Bioethics, which is the study of value judgments pertaining to human conduct in the area of biology and includes those related to the practice of medicine, has been an important aspect of all areas in the scientific field (Bernstein, Maurice, M.D.). It is one of the factors that says whether or not certain scientific research can go on, and if it can, under which rules and regulations it must abide by. One of the most recent and controversial issues facing our society today is the...
- Genetically Engineered Food
Genetically Engineered Food
Millions of people all over the planet suffer from poverty and starvation. One very interesting but experimental solution to the problem of world hunger is genetically engineered food. The process involves the crossbreeding of crops in a laboratory with species that are not plant like. Say for example, that a scientist crossed a fish and a potato. The diversity of this gene mixture is supposed to give this hybrid crop special characteristics like re...
- Y2K: Should We Be Worried?
Y2K: Should We Be Worried?
Some people wonder what Y2K is, and whether it is true or false. Should we be worried about Y2K? Some people are sure it is false, yet the news stresses that it is true. This has many people in fear for their life. Some have been preparing for over a year now because they think Y2K is going to hit and the power will go out and absolutely nothing will work. Should we believe this?
Many people ask, "What is Y2K?". It made me wonder one day, "What does Y2K real...
- Extracting DNA From The Bacterium Escherichia Coli
Extracting DNA from the Bacterium Escherichia coli
Deoxyribonucleic acid is contained in all cells. The structure of DNA makes gene transmission possible. Since genes are segments of DNA, DNA must be able to make exact copies of itself to enable the next generation of cells to receive the same genes. The DNA molecule looks like a twisted ladder. Each "side" is a chain of alternating phosphate and deoxyribose sugar molecules. The "steps" are formed by bonded pairs of puri...

The Eye and Laser Eye Surgery
A Functioning Eye (Emmetropia)
The eye is the organ of sight. It is used in almost everything we do, from playing sport to reading. A normal and well functioning eye can focus objects and images, both near and far, perceive depth and adapt to changes in light.
The perception of depth is due to having two separate eyes creating two separate images, while the ability to adapt to light change is attributed to the iris and the dilator muscles. However these t...
- Melbourne, Australia
Melbourne, one of the most beautiful city's in the world. I have traveled through the USA, Canada & the Bahamas, and still, I find Melbourne is the greatest.
In 1981 I was born in a New South Wales mid-coast town of Port Macquarie. I lived there until I was the age of four, and that's when we made the move to Victoria.
I grew up in Kew, a suburb of Melbourne, not far from the actual city. Most of my family lived there, and was the main cause for the move....
- Current Free Speech Doctrine: Will It Work On The Internet?
Current Free Speech Doctrine: Will It Work on the Internet?
The Internet offers a much greater potential for interactive communication between information senders and receivers than the more traditional methods of communication such as newspaper, radio and television. Freedom of speech ascertained by the constitution is not an absolute right. Depending on the medium through which information is delivered various degrees of the freedom to express one's self is protected. Internet commun...
- Flagella And Cilia
Flagella and Cilia
Flagella are necessary for the active movement of bacterial cells and protozoa. Flagella are single, whip-like structures that propel an organism through an aquatic environment. They use undulatory motions, where the waves of motion start at the base of the flagellum. The size, the volume of the medium, the length, position and width of the flagella on the organism determine the direction and speed propulsion of the cell. There are three different types ...

- Coastal Erosion
With Reference to examples discuss the view that coastal erosion is caused by human intervention as a posed to natural processes.
For many decades the approach to rapid coastal erosion was to build up sea defences, to try and slow down or even stop the erosion. Initially the attempts were thought a success, however after some years it was realised that the power of the sea and waves could overcome human attempts. Only could protection be a success if huge costs ...
- Brazil And Andean Highlands
Brazil and Andean Highlands
The similarities between the societies found in Brazil and those found in the Andean Highlands are relatively few. The Andean Highland dwellers were mostly Incas, found in greatest numbers in Peru. The inhabitants of Brazil were mainly concentrated around the Amazon River Basin area. The Andean Highland people consisted in large part of the Inca civilization (the name of the ruling family, not an ethnicity). However, the geographic location of these societ...
- London Docklands
"Evaluate the success of the economic, social and physical regeneration of The London Docklands."
In Medieval times development occurred on the Thames, where Romans had once settled. Growth of shipbuilding industry led to the development of this area. The London Docks were built between 1700 and 1921. The reason was to ease congestion on the Thames between ships, and the lock gates helped to control the water level in the river. Security was also improved withi...

The Internet: its effects and its future
Internet, its effects in our lives and the future of the Internet:
The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computer...
- Atlantis: We Will Never Know
Atlantis: We Will Never Know
Fantasy is a tough sell in the twentieth century. The world has been fully discovered and fully mapped. Popular media has effectively minimized the legend and the fantastic rumor, though to make up for this it has generated falsities not as lavish but just as interesting. Satellites have mapped and studied the earth, leaving only a space frontier that is as yet unreachable. But standing out is a charming fantasy the modern world has yet to verify or condemn...
