Answer to Question 1

Answer: C

Answer to Question 2

Answer: LTP is an increased EPSP recorded from dentate cells to a single electrical pulse, when that pulse was preceded by high-frequency electrical stimulation of axons that connect with the dentate gyrus cells. There is evidence that more glutamate may be released from the presynaptic terminal button (perhaps due to the influence of nitric oxide from the postsynaptic cell). On the postsynaptic side, LTP is accompanied by physical reorganization of the dendrite, which includes the insertion of AMPA receptors into the dendrite (more sensitivity to glutamate) and the formation of new dendritic spines, which would serve to increase the postsynaptic response to glutamate.

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.
