Sugar taps into a powerful human preference for sweet taste‚ says Marcia Pelchat‚ PhD‚ a scientist at the Monell Chemical Senses Center‚ a basic research institute in Philadelphia. “We’re born to like sugar‚” she says. Sugar is sucrose‚ a molecule composed of 12 atoms of carbon‚ 22 atoms of hydrogen‚ and 11 atoms of oxygen. Like all compounds made from these three elements‚ sugar is a carbohydrate. It’s found naturally in most plants‚ but especially in sugarcane and sugar beets. The

5000m race the runner must use all 3 energy systems ‚ which are ATP‚ aerobic and lactic acid systems to succeed as the race has different areas needed for their use‚ all 3 energy systems contribute regardless of the intensity or duration of the exercise. When the athlete comes to the starting line he/she most probably will want to make a dashing start to the race to tactically get a good starting position‚ so must get off the line‚ in the first 40-50m‚ as hard as he or she can. By getting off the line

Photosynthesis Lab Gizmo website: www.explorelearning.com Class code: EFVNHTVRGY Gizmo Warm-up During photosynthesis‚ plants use the energy of light to produce glucose (C6H12O6) from carbon dioxide (CO2)‚ and water (H2O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they produce‚ but most of it is released. In the Photosynthesis Lab Gizmo™‚ you

Solar Energy The use of solar energy is increasing throughout the world. Solar energy is used to make light‚ run computers and to conserve energy. Today we used fossil fuel to run factories and make electricity but little do the people know‚ one day we are going to run out of oil because it’s not a renewable source. Then what are we going to do ? We would have no other choice then to start using the sun for energy‚ so why not start now ? Solar energy is one of the world’s

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

hydrogen fuel cells. This power source takes in the most abundant element in the universe‚ Hydrogen‚ and yields immense power without combustion or pollution. The three aspects of this scientific breakthrough are the fuel cells‚ hydrogen production‚ and hydrogen storage. Fuel cells are the devices with which Hydrogen is made into electricity. These use a technology much similar to that of something we are very familiar with: the battery. According to the National Renewable Energy Laboratory‚ or
