Who Knows The Answer ?

Water consumption rises because suburban communities use  more water.

Explanation:

Urban sprawl can be described as a wide growth of the urban areas without proper planning. When such a large population starts to live in an urban area then the water consumption would be more. Even the construction process to support the urban sprawl will require adequate amounts of water. Hence, option C is correct.

Other options like option D id false because the usage of more water will lead to an increase in water consumption. The water consumption will not drop.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
