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:

E_{ion} = \frac{RT}{zF} ln\frac{ion_{outside} }{ion_{inside} }

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.

Which provision of the US Constitution is an example of how checks and balances limit the powers of government?
vagabundo [1.1K]

Answer: C. New amendments to the Constitution must be ratified by state legislatures or conventions.

Explanation:

Congress may have the power to enact laws, but they cannot unilaterally change the Constitution. This power would make them absolute and beyond reproach because they could pass laws that are unconstitutional by changing the Constitution.

In view of that, the Constitution prohibits Congress from unilaterally changing it by providing that any new amendments to the Constitution be ratified by three-fourths of the state legislatures or conventions thereby limiting the powers of Congress.
