Living things need water in their cells. Water is the universal solvent - most of the chemicals a cell needs is dissolved and transported in water. Water is an environment where chemical reactions can occur and water is needed in many of those reactions - like the hydrolysis reaction (needed in the break down of food molecules). If a cell becomes dehydrated chemical reactions slow down. Chemical balance of the cell is changed as waste materials are not removed fast enough, food is not broken down, etc. Water also helps regulate the heat that can build up in a cell during chemical reactions. A dehydrated cell = increase in cell temp. Water content of a cell also affects the pH of a cell environment. Certain reactions occur better at certain pH. Homeostasis is maintaining a balance with the the environment. Without water the balance is upset.

Out of the following
A. .08 BAL per hour
B. .05 BAL per hour
C. .018 BAL per hour
D. .015 BAL per hour
The answer is D. This is equivalent to 0.015 g / 100mL / hour leaving your body after alcohol intake. This occurs after the alcohol is broken down by the liver to acetaldehyde and then to acetic acid by alcohol dehydrogenase (ADH). The acetic acid is later excreted through the kidneys and skin. On average, the liver can metabolize 1 ounce of alcohol every hour. It takes approximately 5.5 hours for 0.08 ounces of alcohol to leave the system after intake.
