Which is the constant variable in this experiment? a: mass of marble b: kinetic energy of marble c: potential energy of marble d: height of marble from ground

A.) Mass of the marble

The marble remains the same mass throughout the whole experiment, making it the constant variable. Other variables change, such as height from ground and the energy it picks up with movement.

answer: glucoamylase presented optimum activity at temperature of 55â°c, and, in the glycosidic bonds from the non-reducing ends of starch, resulting in the production of glucose. source and type of fermentation can affect the enzyme's properties
