Answer to Question 1

ANS: D
Water is a major component of the body. It makes up 45 to 80 of an individual's body weight, depending on that person's weight, gender, and age. Leanness is associated with higher body water content. Obese individuals have a lower percentage of body water (as much as 30 less) than do normal-weight individuals. Men have a slightly higher percentage of total body wa-ter than women have. Total percentage of body water in infants and children is substantially greater than it is in adults. In the newborn, water accounts for 80 of the total body weight.

Answer to Question 2

ANS: A
Similarly, a change in pH of 0.3 units equals a two-fold change in H+.
