Catalysts are substances that increase chemical reactions while using less energy. They also remain unchanged after use‚ which enables it to be used repeatedly. Cells have special catalysts called enzymes‚ which are specialized proteins that help accelerate chemical cell reactions. (Evert‚ RF & Eichhorn‚ SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB 2013). This experiment focuses on the enzyme catalase. Catalase breaks down hydrogen peroxide

Energy Debate The use and costs of energy in the United States has been a debate that has been going on for many years and will only continue to go on for more. People believe that decreasing dependency on oil and using alternative sources will be a solution to the many problems we face. The costs are high to do the switch‚ but may pay for its self in the long run. This debate may never be solved because everyone has a different opinion. I feel as though both sides have valid viewpoints. I believe

issues in today’s world is that of energy sources to power an increasing global demand. Traditionally‚ humans have converted energy from natural resources like coal and natural gas for use. However‚ these sources of energy are both nonrenewable and cause large amounts of pollution. As we progress through the 21st century‚ renewable energy sources like solar and wind energy will see increased use to replace traditional sources. One of these sources‚ wind energy‚ is seeing a rise in development because

electrical energy have drastically increased in the past number of years. The sharp escalation of fuel consumption caused the demand for fossil fuels‚ which generate electrical energy‚ to increase as well. Almost 80% of domestic electricity use is used for space and water heating. To reduce the amount of energy produced by fossil fuels‚ the amount of electricity used must be lessened‚ and other renewable methods of electrical energy generation must be found.

Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance

On February 20 2012‚ me and my daughter went to the Gates Planetarium in Denver to see the showing of the Wildest Weather in the Solar System. The first thing we did was to walk around the Space Odyssey and explore some of the exhibit they had. Then we went to see the show which I must say was far more thrilling then I or my daughter could have imagined. When you first walk into the Space Odyssey you are amazed it almost looks as thought your walking on to a spaceship or what I would imagine it

The Origin of the Solar System A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. The disturbance could be‚ for example‚ the shock wave from a nearby supernova. As the cloud collapses‚ it heats up and compresses in the center. It heats enough for the dust to vaporize. The initial collapse is supposed to take less than 100‚000 years. The center compresses enough to become a protostar and the rest of the gas orbits/flows around it
