Why is the outside of a neuron positively charged?Multiple Choicebecause sodium ions gather around the outside of the cell membranebecause calcium ions gather around the outside of the cell membranebecause potassium ions gather around the inside of the cell membranebecause sodium ions gather around the inside of the cell membranebecause chloride ions gather around the outside of the cell membrane

The negative charge across a resting membrane is due to the more __________Blank ions diffusing out of the cell than __________Blank ions diffusing into the cell.Multiple Choicesodium; potassiumsodium; calciumpotassium; sodiumpotassium; phosphate

Opening of sodium channels in the axon membrane causes: Question 26Select one:a.depolarization.b.repolarization.c.hyperpolarization.d.increased negative charge inside the membrane.e.inhibition.

For a neuron to return to rest the axon must alose a negative charge blose a positive charge cgain a negative charge dgain more sodium
