Independent Variable: An independent variable is the variable you have control over, what you can choose and manipulate. It is usually what you think will affect the dependent variable. In some cases, you may not be able to manipulate the independent variable. It may be something that is already there and is fixed, something you would like to evaluate with respect to how it affects something else, the dependent variable like color, kind, time.
Variables Independent: - Temperature Dependent:- Is the rate of reaction(time taken for the milk to curdle). Control Variable:- Same amount of Rennin, same amount of milk, same concentration of Rennin, same type of milk and same amount of time the test tubes were left in water bath(5 minutes).he effect of Temperature on Enzyme Action (Rennin) Aim To investigate the effect of temperature on activity of Rennin Introduction Rennin is an enzyme secreted by walls of the stomach. It acts on a protein in milk causing it to pump into a semi-solid curd. The enzyme is readily available in the form of rennin solution.
