Resting potential and action potential are both names for the measure of electrical voltage within the membrane of a cell. Specifically, these terms are used in describing the transfer of information along neural pathways. Resting potential is a state where cells are at rest. However, if an electrical response or depolarization reaches threshold, then ion channels open, allowing sodium ions to rush into the membrane and increase the voltage measure, firing an action potential along the length of this membrane.
Since the concentration gradient is very large for potassium (where the concentration is much greater ( ~20-30X) inside the cell than outside the cell), reducing this concentration gradient by increasing the concentration of extracellular potassium would result in decreased efflux of potassium through leak channels. This decrease in efflux would result in immediate depolarization of the cell membrane, and would probably be sufficient to generate an action potential (if the depolarization met the threshold level of ~55mV). Now this would only apply to the first generation of an action potential, because if the cell were not able to restore its resting membrane potential (as in the case of increased XC potassium), no subsequent action potentials would be generated. Remember that eventually, equilibrium would be reached between the concentrations of potassium inside and outside the cell, meaning no net flux of those ions, meaning no membrane potential.
"Active" in this context means that energy is required. A substance will flow in a certain direction, through diffusion, without having to provide additional energy. To force the substance in the opposite direction would require energy; the cell has to be "active" to achieve this, and this requires energy.
No, it is not possible if the body is of a fixed dimension and the charges are electrostatic. The potential of a body is directly proportional to the charge on it. If the body is experiencing decreasing potential, it is because charges are being transferred. The charge is changing to effect the change of potential. If a given electrostatic potential is assigned to a balloon, and charges are being transferred as air is let out of the balloon, it is possible to achieve a decrease of potential while maintaining a constant charge density on the surface of the balloon, but that's afield of the question. Charges must be transferred to effect any change in potential, so overall charge will change as potential changes in a body under consideration.
A hypotonic solution causes water to move into the cell. To further elaborate, a hypotonic solution has higher water potential and less solutes as compared to inside the cell. Bear in mind that osmosis is the movement of water from a region of high water potential to a region of low water potential. Therefore, this causes water to move into the cell. I hope this will be helpful!:)

Latent heat is the heat required to achieve a change of phase - for example, to melt ice and convert it to water. As to the relationship with potential energy, latent heat IS a type of potential energy.

To not achieve the highest potential. Or in a good form as in the best.

I think that according to me endless efforts are required to achieve your desired goal. because it's not necessary that you achieve your desired goal by doing first step only so it's necessary to keep pace with the work every day to achieve your desired goal.
Doing nothing will achieve the required aim.
No, all humans have the potential to be saints but only a few achieve that title.

Genetics shape us in many ways including our potential to excel in sports. Training, diet, and other factors play a large role in developing our potential, but our genes may also limit performance. You may have the genetic potential for being a champion athlete, but if you live a lifestyle of overeating and no exercise you are unlikely to achieve that potential. On the other hand, someone with limited genetic potential can find ways to compensate and become a solid performer. Genetics have a large influence over strength, muscle size and muscle fiber compostion(fast or slow twitch), anaerobic threshold, lung capacity, flexibility, and, to some extent, endurance. Soo you are more likely to be born with it.
