Sorry yes it was missing a bit:

If the sodium-potassium-ATP pumps of the nerve cell membrane were to
stop functioning, there would be little change to the resting membrane
potential.

I also have these are they right?


During the relative refractory period it is more difficult to generate
another action potential. yes
Receptor potentials are not conducted along the entire length of the axon. false
a single EPSP is not capable of generating an action potential. true
Disabling the active transport calcium pumps at the presynaptic axon
terminal may disrupt synaptic transmission. true
sympathetic and parasympathetic pre-ganglionic fibres have the same
neurotransmitter substance.true

False, why would the sodium ions leave the axoplasm if there is nothing to make them leave? Sodium/Potassium pumps work from the moment you are born the moment you die, if they stop working you die.

1.During the relative refractory period it is more difficult to generate

2.Receptor potentials are not conducted along the entire length of the axon. false
3.a single EPSP is not capable of generating an action potential. true
4.Disabling the active transport calcium pumps at the presynaptic axon
terminal may disrupt synaptic transmission. true
5.sympathetic and parasympathetic pre-ganglionic fibres have the same
neurotransmitter substance.true
I numbered them for reference, for 1. Definitely true, otherwise action potentials would travel in the wrong direction.
I'm not sure about 2, I think you're right though.
I think you're wrong for 3. Although I can't come up with an explaination, sorry.
4. Disabling the calcium voltaged gated channels will definitely disrupt the synaptic transmission, they cause the vesicles in the presynaptic knob to fuse to the membrane, if there was no calcium around then how do we release neurotransmitters into the synaptic cleft?
not sure about 5.
