Answer:
-35 mV and +56 mV
Explanation:
The membrane potential is the energy that is needed to drive membrane changes across the phospholipid bi-layer membrane.
Ions can move in and out of the cell through protein channels. The movement of the ions is as a result of concentration that affect the operation of ion gates.
The reverse potential is given by the Nernst equation:

where, R = gas constant
T = temperature (Kelvin)
z = ion charge
F = Faraday's charge
The potential is calculated and the result is -35 mV and +56 mV respectively.
Answer:
A stable system cannot be maintained in democracy, because that system needs no moderation and democracy is a moderating policy.
Explanation:
Democracy is a policy established by the will of the people. It opposes authoritarian governance that has the control power emanating from one person, giving that power to the people of a region and allowing that people to make the choices of governance and established policies.
Democracy has a moderating character and for that reason, it needs to be installed in an unstable system, allowing people to have options of choice and through instability, to understand which option is better.
The southeast and northeast areas of the United States are incredibly different in terms of their economies and cultures. This was a major reason for the Civil War.
The answer is: C. Not to try and fix them all, but also not participate in them
Thoreau just want people to know that evil exist and there we might not be able to eliminate them completely. By knowing this, we can always prepare ourselves to take care of evils when we need but not completely lose our mind over it. Simply by choosing not to participate is often enough because the more people do it, the less evil would exist in this world.
