The independent variable is the amount of water consumed by the football players.
The dependent variable is the football players' endurance, measured by how many times they can run up and down the bleachers before catching their breaths.
The coach's hypothesis was that the more water consumed, the more endurance the players will have.
There is not a control group present in this experiment, but it would be the set of players who did not drink a bottle of water before practice.
The experimental group is the set of players who did drink a bottle of water before practice.
The constants in the experiment are the operational definitions of endurance (how he measures their endurance), the amount of water each player drinks throughout the week, and the players used in the experiment.
The lack of a set control group poses a threat to the accuracy of the experiment's results.

cAMP is the second messenger in the pathway.
cAMP or Cyclic AMP is a secondary messenger because it transmits signals from a receptor to a target cell. When the level increases rapidly, it starts following receptor-mediated activation of AC (adenylyl cyclase), and that catalyzes the conversion of AMP (adenosine monophosphate) to cAMP.
The cAMP pathway is also known as the adenylyl cyclase pathway, which is a G protein-coupled receptor that is used in the cell signaling process. It works by activating protein kinase A. Therefore, cAMP is considered a secondary messenger which also regulates various cellular functions like cell growth, cell differentiation, etc.
