Answer: Closed
Explanation:
At resting membrane potential( RMP) sodium channels remained shut, this is because , previously in depolarisation,the voltage gated sodium channels were opened for sodium to diffuse into the Axon. However these channels closed after reaching their refractory period,s.
Therefore a change in the extracellular concentration of sodium will not open them
The answer for the given question above would be the third option. Why there are always more members on the lower trophic levels than the higher trophic levels is because, as <span>energy moves from one trophic level to the next, less and less energy is available for the next level limiting the number on the next level. Hope this answer helps.</span>
