An experiment is performed to test the effect of three different types of water on the growth of a plant. The test is done by using tap water, distilled water, and carbonated water. Choose the statement below that describes the tap water in this experiment. a. The tap water is a controlled variable for all plants. b. The tap water is the control group for comparison. c. Tap water is the only test condition that will cause measurable changes in the dependent variable, plant growth. d. Tap water is one of the three test conditions of the independent variable, the type of water.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
