What Are The Major Components Of Biological Membranes And How Do They Contribute To Membrane Function?.
Number of words: 2565 - Number of pages: 10

.... due to its diverse range of functions. There are general functions common to all membranes such as control of permeability, and then there are specialised functions that depend upon the cell type, such as conveyance of an action potential in neurones. However, despite the diversity of function, the structure of membranes is remarkably similar. All membranes are composed of lipid, protein and carbohydrate, but it is the ratio of these components that varies. For example the protein component may be as high as 80% in Erythrocytes, and as low as 18% in mye .....

Urban Heat Islands

.... of heat energy is slowed and even stopped by the tall building walls that do not allow infrared radiation to escape as readily as do the relative level surfaces of the surrounding countryside. The slow release of heat tends to keep city temperatures higher than those of the unpaved faster cooling areas. On clear, still nights when the heat island is pronounced, a small thermal low- pressure area forms over the city. Sometimes a light breeze, called a country breeze which blows from the countryside into the city. If there are major industrial areas along the .....

.... Pacific rise above normal. In normal, non-El Nino conditions, the trade winds blow towards the west across the tropical Pacific. These winds pile up warm water in the west Pacific, so that the sea surface is about 1/2 meter higher at Indonesia than at Ecuador. The sea surface temperature is about 8 degrees C higher in the west, with cool termperatures off South America, dut to an upwelling of cold water from deeper levels. This cold water is nutrient-rich, supporting high levels of primary productivity, diverse marine ecosystems, and major fisheries. Rainfa .....

"Azizia, 25 miles (40 kilometers) southwest of Tripoli, in Libya, holds the record with 136.4o F (58o C), while Death Valley, Calif., comes close with 134o F (56.7o C). "(Genius book of world records 2000) Winters are cold in middle-latitude deserts, located far from the equator. "At Luktchin in central Asia the average temperature in July is 90o F (32o C), while the January average is 13o F (-10.6o C)--a range of 77 Fahrenheit degrees (42.6 Celsius degrees)"(Compton's Encyclopedia).
