<span>The answer to this question would be: e. increase the rate of the glycolytic reactions.
</span>Lack of oxygen limits the possible chemical reaction that can be done to produce energy. In the anaerobic environment, fermentation of glucose would be the source of energy for bacteria. The net amount of ATP can't be increased, so you need to increase the rate instead.
It would be .5. If there is a probability that two thing could happen it would be 50 50 shot.
The correct answer would be "Density is the amount of matter in a certain volume"
A dependent variable is one whose value depends on another variable. Hope that helps you answer the question!
