Answer:
Height of marble from the ground
Explanation:
An independent variable is the variable in an experiment that you change to see if it has an effect on the dependent variable. In this case, Jack wanted to see whether the position of the marble on the ramp (which would be the height) has an effect on the kinetic and potential energy of the marble, then the height would be the independent because it is what is being changed.
<u>Added note:</u>
The dependent would be the kinetic and potential energy and the constant would be the type of marble.
The changing temperature, odor and bubble formation all indicate that the yeast is responding to external stimuli. This is a characteristic of living organisms. They will respond to changes in their environment. The changes that occur here are a result of the yeast using the sugars in the dough to carry out respiration.
