4.4ai. The price elasticity of demand is given to calculate the new price. The fruit stall has 100 peaches initially but 10 peaches are rotten. It means the number of remaining peaches is 90 units. Therefore‚ the question provides the factors such as initial quantity‚ new quantity‚ initial price which are 100‚ 90‚ 1 respectively. Let the new price be x. Therefore‚ we will choose $1.2 per unit as the new price to sell the remaining peaches. 4.4aii. Case 1: If I do not discover the

Sodium was first discovered by Sir Humphrey Davy in 1807. This element is the 11th element found on the periodic table; located in group 1 and period 3. Its chemical symbol is Na and it is classified as a metal.

Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable
