Of all the species that have existed on Earth 99 percent have gone extinct and even fewer make it into the fossil record and a very small fraction of those that fossilize are actually found even partially complete.

And also it is highly unlikely that most would be found complete‚ due to the number of natural disasters and processes that have happened from the animal’s death to whenever it is discovered.

Iodine clock reaction This is the hydrogen peroxide/ potassium iodide ‘clock’ reaction. A solution of hydrogen peroxide is mixed with one containing potassium iodide‚ starch and sodium thiosulfate. After a few seconds the colourless mixture suddenly turns dark blue. This is one of a number of reactions loosely called the iodine clock. It can be used as an introduction to experiments on rates / kinetics. 63 Lesson organisation This demonstration can be used at secondary level as an introduction

scientific knowledge has helped humanity comprehend the complex relationships in ecosystems and the devastating effects of human interference. As a result we have become increasingly aware of the need to protect and manage the ecosystems that we do have remaining for their utility‚ genetic‚ intrinsic and heritage values and also for the need to allow natural change and thus evolution to take place. Natural ecosystems have provided much that has been of benefit to humanity and with careful protection

Positive Impact: Although the white goby eat the cyprinids it does not have a large impact on the cyprinids compared to eleotrid which feeds on three endemic cyprinid species. Negative Impact: The white goby swims in fresh water. In Lake Mainit the fish was found in their fresh water container and this was the farm’s main water stock
