One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, when placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3- and a hydrogen ion (H+). Thus,

H2CO3 ↔ HCO3- + H+

If the pH of the blood increases, one would expect
A) a decrease in the concentration of H2CO3 and an increase in the concentration of HCO3-.
B) an increase in the concentration of H2CO3 and a decrease in the concentration of HCO3-.
C) a decrease in the concentration of HCO3- and an increase in the concentration of H+.
D) an increase in the concentration of HCO3- and a decrease in the concentration of OH-.
E) a decrease in the concentration of HCO3- and an increase in the concentration of both H2CO3 and H+.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
