Final answer:
Replacement is the type of neuron regeneration that requires multipotent neural stem cells and can be contested by distance.
Step-by-step explanation:
The type of neuron regeneration that would require a population of Multipotent neural stem cells and would be contested by distance is replacement.
This type of regeneration involves replacing damaged or dead neurons with new, functioning neurons. Multipotent neural stem cells have the ability to differentiate into various types of neurons and can be used to replenish the damaged cells.
Distance is a challenge in the process of replacement, as the new neurons need to grow and establish proper connections with other neurons, which can be difficult if the damaged area is far from the source of the multipotent neural stem cells.
