Which soil and plant condition indicates a need for irrigation

rooting depth

Explanation:

The need for water of plants is determined by the degree of soil moisture. The optimal soil moisture for most vegetable plant species is between 70 - 90%.

When the soil moisture is below 60%, most plants show a symptom of lack of water in the form of sports development of plants, flowers, and fruits fall off, while excessive watering can lead to rot of the plant or the plants have a lush increase, they become thin…

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.
