The amount of oxygen in a fish tank is a that affects the amount of fish that can live in the tank

Our freshwater that we use can be or ... Movement. • Dissolved oxygen. (+ other gases). • pH. • . • Salinity. • Fish ... Dissolved is the amount of oxygen in water that is for eguli minutes

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.
