Question

during a resting state, the inside of the neuron is (negatively/positively) charged relative to the outside.

Explanation:

In a resting neuron, the resting membrane potential is established by the distribution of ions (like $K^+$, $Na^+$) across the membrane. The inside has a higher concentration of negative ions (and relatively more $K^+$) and lower $Na^+$ compared to the outside, making the inside negatively charged relative to the outside.

Answer:

negatively
