In solution hypotonic to the sheep’s red blood cells‚ the red blood cells will lyse‚ as a result of the water entering the cell via osmosis. First‚ a stock solution of NaCl was prepared at concentration 1.0M. Working solutions were made ranging from hypotonic to hypertonic with a negative control at isotonic solution (150mM). The solutions were diluted up to 4 mL into 5 test tubes‚ (0mM‚ 0.13mM‚ 0.15mM‚ 0.17mM‚ 0.3mM 0.5mM) using distilled water to dilute the stock solution. The working solutions

Pediatric Rehydration is the replacement of body fluids lost during dehydration. Dehydration is a condition in which there is not enough fluid or water in the body. There are many ways that dehydration can occur‚ including vomiting‚ diarrhea‚ or excess sweating. In most cases‚ rehydration involves the replacement of not only fluids but also carbohydrates and basic body salts (electrolytes ). While rehydrating and recovering from dehydration‚ it is important for your child to: • Continue to eat to maintain

Experiments were conducted that had athletes run for several miles at certain levels of hydration and dehydration. Shirreffs found that with as little as a two percent reduction in body mass due to water loss athletes performed significantly worse as their dehydration continued. Not only did dehydration cause a reduction in athleticism‚ but it was found motivation to exercise was
