Explanation:

Green house and hydroponics farming is an innovative farming method that allows crops and plants to grow without soil. The plant and crop roots are supplied with mineral solution essential for its growth. Also the land requirement for such farming is very less and better quality crops can be grown.  

Alley cropping is practiced with the aim of preventing soil erosion. Large woody trees are planted in multiple rows along with crops and plants in between these rows.  

Terrace farming is practiced in mountains. It helps in preventing water loss as well crops in subsequent terraces get water as it flows from top to bottom naturally.  

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.
