these occur naturally due to the high evaporation rates and atmospheric accession of salt. There are‚ however‚ a rapidly increasing amount of saline wetlands occurring due to secondary salinization. This salinisation is resulting in the loss of freshwater macro-invertebrate species. (A) Specific descript of issue Land management practices for the purpose of agriculture in the aptly named “wheatbelt” of Western Australia have led to the secondary salinization of many rivers‚ streams and wetlands.

Climatic Change and Its Effect on Society There has been a significant climatic change that has taken place throughout the years on Earth. These changes have effected society in more than one way. However‚ there is nothing society can do about the long term influences of climatic changes. Society has tended to address the short term effects of climatic changes that influence the global temperatures within the life span of present generations. The following will show how climatic changes does effect

The goal of this project is to test whether alcohol and caffeine has an effect on heart rate‚ using the freshwater crustacean‚ Daphnia magna‚ as the experimental subject. For humans‚ alcohol works as a depressant‚ slowing down the heart rate of the consumer; caffeine works as a stimulant‚ increasing the heart rate of the consumer. The heart depends on an internal pacemaker system to keep it pumping consistently and at the right speed. Alcohol disturbs this pacemaker system and causes the heart

of salts and water in the aquatic environment fish‚ and all vertebrates‚ evolved to utilize a very specialized organ to solve this problem: The Glomerular/ Vertebrate Kidney (Washinton). In early evolving species‚ fish were beginning to live in freshwater systems after entire millennia of living in the oceans (Washington). This meant that their cells had a higher concentration of salts than the environment. According to osmosis‚ that meant that excess water (trying to diffuse the salts) and the loss

adopted to resolve conflicts of interest in the management of water resources in trans-border river basins. Water conflicts often enough results from opposing interests of water users. This is especially true in trans-border river basins where the freshwater river travels across more than one country. Conflicts among water users arise as water quality or water quantity degrades and no longer meets the demands of each country. Today we will be discussing on some examples of trans-border river basins
