Draw a picture to illustrate resting potential, and explain how it transmit signals in neurons.

The resting potential is the potential between the neuron and the outside of the cell is -70 mV. There are more potassium ions inside the neuron that outside. To balance this, the concentration of sodium ions outside the neuron is higher than the inside.

No that answer is wrong. you have written the function of mitochondria in chloroplast and function of chloroplast in mitochondria.
