After 10 years, the isotope would have had two half lives. For each half life, half of the material reacts. Therefore, after one half life, 50% remains. Then, after a second, 25% remains. D is the correct answer.

Answer:
Generally, K+ ions ensures re-polarization of the membrane potential. It always ensures that the neuron returns its resting state, protecting the neurons and ensuring episode of rest before the next action potential.
K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.
Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.
Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.
