• B) Graded potentials are caused by ligand and mechanically-gated channels that are most frequently found in dendrites and cell bodies.
• C) Graded potentials are caused only by Na⁺ and K⁺ flowing through channels.
• D) Graded potentials are both depolarizing and hyperpolarizing, which means they can't occur in axons where only depolarizing signals occur.
