In cell division, the cell that is dividing is called the "parent" cell. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.
Answer:
The inside is becoming positive.
Explanation:
The membrane potential may be defined as the difference in the electric potential between the outside and inside of the cell. This potential difference is important for the conduction of nerve impulse.
The depolarization of the cell occur due to the movement of sodium ions inside the cell. The depolarization of the cell changes the membrane potential from -70mV to +30mV. The inside of the cell become more positive than outside of the cell.
Thus, the correct answer is option (a).
