Since the body’s demand for oxygen increases as physical exertion increases, a university athletic coach thought that giving her athletes this oxygenated water would result in better performances.  To test this idea, the coach divided her runners up into two groups.  During practice, one group was given the super charged, oxygenated water to drink.  The other group was given regular water.  Both groups completed the same workout and drank the same amount of water (either oxygenated or unoxygenated).  At the end of practice, she had all the athletes run 400 meters as fast as they could.  She compared the times of the runners who had consumed regular water to those who had consumed the oxygenated water during practice.  The coach found that the average time of the oxygenated water drinkers was significantly faster than that of the runners who had consumed regular water during practice. Which of the following is the hypothesis tested by the coach in this experiment? a- Oxygenated water is healthier for athletes compared to normal water. b- Increased oxygen consumption improves athletic performance. c- If runners drink oxygenated water, they will run faster.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
