The neurons of an alien species are exactly the same as humans except thier extracellular fluid of contains a potassium compound which is unable to move into the cell. What would be the most likely difference between the action potentials of the alien's neurons compared to human's?
A) The alien's action potentials would have a shorter refractory period due to electrostatic force.
B) The alien's action potentials would have a lower threshold because of more postive ions outside the cell.
C) The alien's action potentials would have a higher peak since they would start at a less negative value.
D) The alien's resting potential would be less negative due to diffusion.
