OCEAN THERMAL ENERGY CONVERSION Abstract Ocean Thermal Energy Conversion (OTEC)‚ to me‚ is the developing worlds answer to OPEC (Organization of Petroleum Exporting Countries). We will no longer have to depend on oil supplies from other countries. OTEC is an efficient‚ clean process‚ which utilizes the difference in temperatures between the oceans surface and its depths to produce energy. The ocean thermal energy conversion process works something like a refrigerator in reverse. The

The primary challenge of inhabiting a high salinity environment is balancing osmotic pressure. Since these environments contain high salt concentrations‚ water from the cells of organisms spontaneously diffuses out of the cytoplasm in order to restore osmotic balance. This leaves cells dehydrated and thus‚ eventually causes cell death. In order to ameliorate this predicament‚ halophiles use one of two unique strategies that function to increase the osmolarity of the cell‚ both of which as illustrated

Introduction There are about a million different kinds of seeds in our world with all of the different types of plants that we have. One type of seed that takes between three to five days to germinate is a daikon radish. The radish (Raphanus sativus ) originated from China. It was commonly seen and eaten by the people of Egypt long before the Egyptians started to construct their very own pyramids. Later on‚ radishes became a common vegetable to eat in Greece‚ and since the radish meant so much worth

The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

effect the environment. Abiotic and biotic factors combine together to create an eco system. An ecosystem is a community of living and non living things combined together carefully. Abiotic factors include sunlight‚ temperature‚ water‚ turbidity‚ salinity‚ pH‚ nitrides D.O. These factors have a major effect on the biotic factor in the eco system. Turbidity Turbidity is the measurement of the clearness of the water. The major determination that can affect the turbidity of the waterways is human

Article on Natural environment Natural environment The natural environment encompasses all living and non-living things occurring naturally on Earth or some region thereof. It is an environment that encompasses the interaction of all living specie. The concept of the natural environment can be distinguished by components: Complete ecological units that function as natural systems without massive human intervention‚ including all vegetation‚ microorganisms‚ soil‚ rocks‚ atmosphere and natural phenomena
