Quart
The liter is a metric unit of volume. The U.S. Customary unit of volume most nearly equal to the liter is the quart.
A quart is a unit of measurement used to measure the volume of a liquid (how much liquid a container can contain). A quart is a quarter of a gallon and it is divided into two pints or four cups. There are three types of quarts that are been used. They include the; the dry quart of the US customary unit, the liquid quart, and the imperial quart. They are all approximately equal to one metric liter.

Answer:
a. polarized
Explanation:
The whole living cell and in particular the nerve cells show electric potential difference between the inner and outer faces of their cell membrane.
The resting potential of a cell refers to the difference in electrical potential that the inner and outer faces in the membrane of a neuron that is not transmitting nerve impulses. The resting potential value is around -70mV (milliVolts). The negative sign indicates that the interior of the cell is negative relative to the exterior.
The existence of the resting potential is mainly due to the difference in concentration of sodium (Na +) and potassium (K +) ions inside and outside the cell. This difference is maintained by a mechanism of active ion pumping through cell membranes, in which sodium is forced out of the cell and potassium in.
At rest, the alternation between passive and active ion transport occurs. There is passive input of sodium (Na +) ions, which are subsequently actively expelled, while potassium (K +) ions enter actively. Then K + passes passively from the cell, making the external medium positive relative to the internal medium. With this, the cell becomes polarized.
