    every protein that our bodies make. Similarly‚ the DNA of each plant and animal seems to be ultimately responsible for the size‚ shape and function of every protein that each of them makes. We will now take a small overview on history‚ physical properties ‚ chemical properties of DNA. Overview on History : DNA was first isolated by Friedrich Miescher ‚ who in 1869 discovered a microscopic substance in the pus of discarded surgical bandages that he called ‘NUCLEIN’ Finally in 1953‚ working together

    QUALITIES OF GOOD WATER by Dr. Robert O. Young There are many measurements of water‚ but the most important for determining the best water to drink are‚ the pH‚ oxidative reduction potential—or energy potential/activity—molecular structure‚ and purity. Science has helped us to determine that the best measurements for our drinking water are the pH and purity‚ but little understood is the importance of the molecular structure of water. Assuming that most waters that humans are drinking are purified

    IB Biology Sheran Gu Meghan Lena Nov. 15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site

    The Effects of Varying pH on Enzyme Activity A lab was conducted to test different pH balances on an enzyme. Introduction: Enzymes are protein catalysts that speed up a chemical reaction without being consumed in the process. Enzymes are three-dimensional structures that consist of one or more polypeptide chains. The polypeptide chains form an active site (where a substrate will fit into). Enzyme molecules are folded into a very specific shape held together by the different forces of attraction

    used to do useful things such as propel an automobile or a 747. The principles of thermodynamics govern the conversion of thermal energy to other‚ more useful forms. For example‚ an automobile engine can be though of as a device which first converts chemical energy stored in fuel and oxygen molecules into thermal energy by combustion‚ and then extracts part of that thermal energy to perform the work necessary to propel the car forward‚ overcoming friction. Thermodynamics is critical to all steps in this

    Thomas Newberg Chemical Weapons Convention Historically chemical weapons are rarely seen in combat but when they are they are used to great effect‚ killing thousands and injuring many more. Chemical weapons were first used in combat in May 1915 when the Germans released chlorine gas against the French in the Battle of Ypres. Over the course of WWI new chemical agents were developed including cyanide‚ phosgene and mustard gas. The Geneva Protocol of 1925 condemned chemical weapons but states that
