For each of the following, indicate whether the condition will cause the membrane potential to become more positive, more negative, or largely unchanged when compared to the normal physiological resting membrane potential.
1. triple the number of na+ leak channels
2. double the size of cells without adding channels
3. double the number of k+ leak channels
4. double the number of closed channels for k+
5. double the concentration of k+ outside the cell
6. decrease the concentration of na+ outside the cell
