1. Interpreting GraphsAccording to the graph at left, what is a temperature range for optimal bacterial growth?2. VariablesA scientist set up three beakers, each containing 500ml of water and 10 worms. The scientist then added 10 drops of Chemical A to the first beaker, 50 drops of Chemical A to the second beaker, and 0 drops of Chemical A to the third beaker. The scientist counts the number of worms alive every 12 hours for 1 week. CONTROL GROUP:INDEPENDENT VARIABLE:DEPENDENT VARIABLE:3. What is the highest magnification for the microscope at right?
