Sean wants to know whether monarch butterflies prefer to feed from flowers of a certain color. sean placed different colored lantana flower plants in separate 1-l terra cotta flower pots. he has a white lantana, purple lantana, orange lantana, yellow lantana, and red lantana. sean set the pots on his back porch. he then observed the pots for four days and recorded how many visits each of the flower plants received from a monarch butterfly. what is the variable in sean's experiment?

The INDEPENDENT VARIABLE is Flower color.
the DEPENDENT VARIABLE is how many visits received
the CONSTANT VARIABLE is the type of butterfly, and amount of butterflies used.

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.
