How does a lotus flower survive in aquatic climate?

Explanation:

Leaves of Lotus plant are very wide and disc shaped. This allows them to float on water and absorb large amount of sunlight. The stem and leaf surfaces of Lotus are coated with a wax which is very difficult to wet. Therefore, it keeps the surfaces free from excessive water even in water rich environment

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.
