Why is it critical that the K+ channel activation gate responds slightly more slowly to depolarization than the Na+ channel activation gate?
A. If they showed identical response times, movements of Na+ and K+ ions would cancel out each other's effects on membrane potential changes. B. If they showed identical response times, movements of Na+ and K+ ions would magnify each other's effects on membrane potential changes, creating dangerously large action potentials. C. It is not critical and there would be no change in action potential characteristics if this difference in response time did not exist.

It has been argued that cutting old-growth forests and replacing them with plantations of young trees would help to alleviate the threat of global greenhouse warming. What important fact does this argument ignore?
A) Forests play too minor a role in global CO2 dynamics, which are affected far more by marine algae. B) Young trees fix carbon at a lower rate per unit mass than old trees. C) Most of the biomass of the cut trees would be added to the atmosphere as CO2 within a few years. D) Most of the young trees would die within a few years.
