Answer:
The correct answer is -
Independent variable - change in the concentration of carbon dioxide
Dependent variable - bubbles produced
Explanation:
The independent variable of an experiment or study is a variable that is subject to change or being manipulated during the study to find the response on the dependent variable. The concentration of carbon dioxide is here manipulated to find the change in the amount of bubble produced.
The dependent variable is a response that is carried out by the change or manipulation of the independent factor. In this case amount of bubbles is the dependent variable.
Thus, the correct answer is -
Independent variable - change in the concentration of carbon dioxide
Dependent variable - bubbles produced
It allows the cell to adjust a metabolic activity to environmental conditions. That enables the cell to save a lot of energy as transcription and translation of genes is very energetically costly
