The addition of another person at each end of the rope does not affect the results of the tug of war.
The addition of another man at each end of the rope does not affect the results of the tug of war because the forces exerted by each individual are independent of each other.
In a tug of war, the force applied by each person depends on their individual strength and the technique used to pull the rope.
The total force exerted on the rope is the sum of the individual forces, and it remains the same regardless of the number of people at each end.

Active transport requires energy to move molecules across a cell membrane because it goes against the natural concentration gradient
Because active transport works against the natural concentration gradient, which moves molecules from a region of lower concentration to a region of higher concentration, it requires energy to move molecules across a cell membrane.
To transfer molecules down their concentration gradient (from high to low concentration), passive transport methods like diffusion and assisted diffusion, which don't require energy, are in contrast.

Answer:
Active transport requires energy because it is not a passive process. The molecule has to go against the concentration gradient. Hence it requires energy to be carried by the carrier proteins.
The energy is used is ATP, which comes from respiration
Elastic potential energy
Explanation:
An extended spring stores elastic potential energy.
An elastic potential energy is the energy stored in an elastic object when force is applied to deform it.
