At the resting membrane potential of an excitable cell, the driving force for ions is?

At a resting membrane potential of -90 mV, there is not only a large chemical driving force, but also a large electrical driving force acting upon external Na+ to cause it to diffuse into the cell.

Explanation:

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
