the substance being fermented,
the yeast used,
exposure to oxygen,
time,
sugar levels,

Any of these can be independent variables. The sugar and alcohol levels can be dependent variables.

What causes change in a dependent variable?
The dependent variable is dependent on the independent variable, so when the independent variable changes, so does the dependent variable.
What is the dependent and independent in a experiment?
The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
Why is the output value called the dependent variable?
because it can change according to the independent variable. this dependent variable depends on the independent variable for its output. the independent variable is not affected by the dependent variable because the independent variable if found out first.
What is the definition of an independent and dependent variable?
A independent variable is a particular variable that is being manipulated and the dependent variable is the result of the change of the independent variable. Ex. In an experiment the independent variable is what is being tested and the dependent variable is the result of the test.
Positive correlation implies what--dependent variable improves as independent variable increases or dependent variable decreases as independent variable increases or?
dependent variable improves (or increases) as independent variable increases
