<span>A failure of homeostasis -- the balance of essential physiological states -- means disaster for the organism. Failure to maintain body temperature leads to hypothermia or heatstroke. Failure to maintain energy balance can result in obesity and diabetes. Failure to maintain calcium balance in the blood leads to hypocalcemia or hypercalcemia. Failure to maintain water balance results in dehydration or hyperhydration. </span>
Dynamic equilibrium: Particles are moving into and out of the cell, but their concentrations remain stable.
The charge of the electrical impulses sent from stimuli is extremely positive. Thus, the correct option is A. The net charge of such electrical impulses is positive because of the positively charged ions of the Na+.
<h3>What is an electrical impulse?</h3>
An electrical impulse may be defined as a nerve impulse that contains an electrical signal which travels throughout the body by the axon terminal.
In the resting potential state, the potential difference is -80mV, while after reaching the electrical impulse it changes to +40mV. This happens due to an electrical imbalance between sodium and potassium influx and efflux.
Therefore, the correct option is A.
