Aforest was converted into a natural park this process required constructing roads and highways to make it accessible for people construction of roads inside a forest has resulted in

The process is habitat fragmentation.

Notwithstanding causing direct mortality, roads constructed between the forests can have various aberrant effects which lead to condition called habitat fragmentation. This can result from either creature not having the option to go across the road without being hurt or through shirking of the road.

For instance, a few snakes have been appeared to pivot and not go across the road when they experience it. Some creatures keep away from the outside of the road in any event, when there are no vehicles driving on it.

Flying creatures that normally fly short good ways starting with one tree then onto the next may likewise be reluctant to fly over a huge open space, which confines their developments crosswise over roads.  

b. regulated is the actual answer to your question.

explanation:

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.
