Explanation / Answer

33) option is 2: during the resting membrane potential inside of the neuron is negative because of the accumulation of more sodium ions are present outside and more potassium ions are inside.outside the neuron is positively charged

34)option 1: sodium potassium pump maintain the resting potential by moving three sodium ions out and two potassium ions inside

35) option A: during depolarization the inside becomes more positive due to influx of sodium ions as they are positively charged

37)the junction of axon with another cell is called synapse

38) b: when the action potential reaches the end of axon tiny bubbles with full of neurotransmitters are released in to the synaptic cleft

39 and 40 are not visible
