Wherever there is water, there is usually mold. From a particular mold Penicillium notatum, the first antibiotic was discovered by Sir Alexander Fleming and was called Penicillin. It is a marine biotechnology where subsequent research on other marine fungi was based.  

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.
