Arrange 5 stages of an action potential in correct order. Cards: 'Resting potential (-70mV): K⁺ leak channels open, Na⁺/K⁺ pump active', 'Stimulus reaches threshold: Na⁺ channels open', 'Depolarization: Na⁺ rushes in, membrane reaches +30mV', 'Repolarization: Na⁺ channels close, K⁺ channels open, K⁺
