Mobile phones harm body cells and damage DNA Radio waves from mobile phones harm body cells and damage DNA in laboratory conditions‚ The research project‚ which took four years and which was coordinated by the German research group Verum‚ studied the effect of radiation on human and animal cells in a laboratory. After being exposed to electromagnetic fields that are typical for mobile phones‚ the cells showed a significant increase in single and double-strand DNA breaks. The damage could not

Animals are Our Lives “Clearly‚ animals know more than we think‚ and think a great deal more than we know.” - Irene M. Pepperberg. I agree with this quote because I believe that animals help humans more than we give them credit for. Many animals are service animals or just companions. Short‚ tall‚ or small‚ animals are an important part of making humans who we are today. To begin with‚ animals can save peoples lives in some situations. For example‚ in the chapter‚ “Dogs Make Us Humans” from the

Chemistry is one branch of knowledge that grew from human curiosity about the world and has played a central role in the development of the modern world. Chemistry is the study of the composition of matter‚ the stuff things are made of‚ and the changes that matter undergoes. Now‚ we may not think chemistry plays such a big role in our life but it perhaps more than any other branch of science has bettered our lives. Almost anything we touch today has benefited from chemical technology‚ and there for

CHE 242 Tutorial 3: Problems & Answers Week 4: Feb 2- 6‚ 2009 1. Consider a gas that occupies 1.00 dm3 at a pressure of 2.00 bar. If the gas is compressed isothermally at constant external pressure‚ Pext‚ so that the final volume is 0.500 dm3‚ what is the smallest value Pext can have? Calculate the work involved using this value of Pext. Solution For compression to occur‚ the value of Pext must be at least as large as the final pressure of the gas. P1 = 2.00 bar‚ V1 = 1.00 dm3‚ V2 = 0.500

Baking Project There are several chemical reactions taking place in the general baking of cakes. Every ingredient has its own function and causes a different reaction Synthesis: * Egg yolks (modify molecule’s structure) helps the oil-based and water-based components of the cake mix together. When eggs are cooked‚ the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked‚ it helps form a
