Which two factors are most likely to cause a plant to wilt? A. Increased rainfall
B. Low turgor pressure
C. Lack of water
D. High turgor pressure

Lack of water, low water pressure

Explanation:

When there's a lack of turgor pressure, the plant can't support itself and have its shoot/s and stem point straight, so the plant would just wilt.

When there's a lack of water, plants start to wilt to conserve as much water as possible, since this reduces water loss by transpiration as the surface area of the leaf exposed to the atmosphere is lower.

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.
