Fill in the table below At the end of the activity, the student can :1. Determine the effect of temperature on reaction rate below andabove the optimum.2. Determine the optimum temperature of the enzyme used.Objectives:Reagents: Saliva, 4 ml 1% starch, 4 drops iodine in KI, 4 ml benedict's reagent.Materials: Thermometer, 8 test tubes (20 ml), test tube rack, brush, holder, tripod,wire gauze, 250 ml beaker, 10 ml graduated cylinder, dropper, alcohol lampProcedure:1. Prepare 5 test tubes. Place 1 ml of 1% starch and add 10 drops of saliva toeach tube. Mix thoroughly.2. Place the first tube in ice water, the 2nd tube leave at room temperature, the 3rdtube in 40°C , the 4th tube at 60°Cwater bath and the 5th tube boil for 2minutes..3. Leave the 4 tubes in their respective temperatures for 30 minutes. The 4th tubeallows to stand for 30 minutes after heating for 2 minutes.4.

At this point, 5% of the population had bat wings and 95% of the population had bird wings. The two wing types interbred with each other, and over many generations, the population shifted so that 40% of the people had bat wings and 60% had bird wings. 9 | Page 12/ 20 Questions: 1.
