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.
Hello, our reflexes are governed by the spinal cord since these actions happen quickly thus needing to bypass the brain. The other functions, meanwhile, are controlled by the brain itself, with motor skills and involuntary functions such as respiration being controlled by different parts of the brain.

The theory of spontaneous generation stipulated that life emanated spontaneously from ‘nothing’.

This showed that maggot was as a result of hatched eggs that were deposited by flies. Life, therefore, emanates from life.
<span>Renewable energy is the type of energy derived from natural resources such as solar energy that comes from the sun, the geothermal energy, hydroelectric power from the water. The renewable energy will not run out based on the fact that it is renewable and comes from our natural resources such as the sun, the water, the wind and a lot more. It does not also emits potential hazards, carbon dioxide and other pollutants. The maintenance of this type of energy is also very affordable unlike other energy that are of high maintenance.</span>
