Answer:
Fish utilise a counter-current system in order to maximise the amount of oxygen that can extracted from water. Water has a much lower oxygen content than air and as such fish need a much more efficient system that can extract a much higher proportion of oxygen from the surrounding water.
Explanation:
Nerve cells, also called neurons, are specialized cells for the nervous system that is responsible for movement and response system. This is done through action potentials that lets the neurons generate a electric synapse to that received stimuli.
When there is an unequal amount of charges between the sides of the neurons, this can be described as diffusion potential or the resting potential.
