The interior surface of a neuron's plasma membrane at resting membrane potential will have a negative charge and contains less sodium than outside of the cell positive charge and contains more sodium than outside of the cell negative charge and contains more sodium than outside of the cell positive charge and contains less sodium than outside of the cell

The answer is 'negative charge and contains less sodium than outside of the cell'. This is called the resting potential. After depolarization, the ion channels open up and the intracellular sodium ions are pumped out of the neurons hence making the inside of the neurons electronegative compared to the extracellular matrix. The membrane potential is usually -70mV.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

this could be newton#'s law of cooling. the cooling curve is exponential
