a control helps to increase the reliability of the results. it allows a scientist to compare it to other group(s) in an experiment. if a scientist notices a significant different btwn the control and the other groups, he can logically conclude that the independent variable has an impact on the dependent variable.
a variable is any factor, trait or condition that can exist in differing amounts or types. there are usually three tpes of variables in experiments: the independent, dependent and contolled. the independent variable variable is the one that is changed by the scientists to figure it's affect on something.
Answer:
Reactions require an input of energy to initiate the reaction; this is called the activation energy (EA).
Activation energy is the amount of energy required to reach the transition state.
The source of the activation energy needed to push reactions forward is typically heat energy from the surroundings.
For cellular reactions to occur fast enough over short time scales, their activation energies are lowered by molecules called catalysts.
Enzymes are catalysts
