on Reactive Oxygen Species Abstract Antioxidants are among key molecules for a healthy living. Antioxidants are molecules that prevent damage of cells through inhibition of oxidizing agents such as free radicals. This experiment was aimed at investigating the role of antioxidant on the inhibition of reactive oxygen species. To demonstrate this‚ quercetin was used as antioxidant and its effect on reactive oxygen species examined. RAW 264.7 cells were used as

Geothermal energy What is geothermal energy‚ and how can we use it in society? Geothermal energy is the use of the Earths very own energy. It’s renewable‚ clean and can range to easily acquirable hot springs on the surface or hot rock found a few miles below the surface. Or you can go a bit deeper and hit the extremities of the molten rock (magma). In the US around 80% of all geothermal hotspots are found on the western states i.e. Alaska and Hawaii. Wells are drilled deep into the underground

Solar Energy Alternative energy resources are being closely evaluated because of the depletion of nonrenewable resources‚ such as fossil fuels. Fossil fuels and other nonrenewable resources have damaged earth because of the amount of pollution that is released some‚ in which is known as Carbon Dioxide. Massive amounts of Carbon Dioxide are that is released into our environment every year further damaging our planet. Scientist has been effectively working on ways of conserving energy that is

Analysis of Oxygen bearing Organic compounds Abstract The Unknown sample in the experiment can be tested to yield results such as 1° (primary)‚ 2° (secondary)‚ 3° (tertiary) alcohols. Tests such as the dichromate test‚ Tollen’s test‚ Lucas test‚ DNPH test and iodoform test would be very useful in determining the type of alcohol that the unknown sample belongs to. In the experiment‚ the unknown sample underwent series of testing to identify what property of alcohol it belonged to and the result

Waste-to-energy Taking Care of Garbage Michelle Rowland Buena Vista University Waste-to-energy Taking Care of Garbage We all have to share this world with its limited resources. We must take advantage of all resources we have‚ regardless if they came from the earth‚ are man made‚ or are waste products. The average person in America throws away 3.7 pounds of garbage every day (Resource Recovery Public Works‚ 2009). It is no surprise that this leads to landfills that are filling faster

Work Renewable and Non-renewable energy sources &Fuels: Renewable energy comes from natural sources that are constantly and sustainably replenished. The most common renewable energy sources are biomass‚ hydroelectric‚ geothermal‚ wind power and solar power. Sunlight is the source of most renewable energy power; the sun can be used to produce solar energy which is electricity for heating‚ cooling‚ lighting homes and transportation.
