The membrane potential of a neuron is measured from the inside of the cell relative to the outside. For a newly discovered neuron with properties that are not yet known, a researcher measures that the outside of this neuron is 60 mV more positive compared to the inside. What is the membrane potential

It is -60 mV.

Explanation:

The membrane potential of a neuron is measured as the difference between its' outside and inside values and the outside value should be greater than the inside value.

fFor the newly discovered neuron with still unknown properties, measuring the outside of the neuron as 60 mV more positive or higher than the inside means that the membrane potential of the neuron is -60 mV since it is calculated as inside value - outside value.

I hope this answer helps.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
