<span>Electrocardiography is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin. These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle's electrophysiologic pattern of depolarizing and repolarizing during each heartbeat. It is a very commonly performed cardiology test.

Ion gated channels are used. Usually, they are active transport , they use ATP (energy).
The answer is B: <span>electricity is required to produce the hydrogen fuel. This could still be polluting because much electricity is produced using fossil fuels. However, this question is a bit misleading. If electricity used to manufacture hydrogen is sourced from renewable energy, such as hydropower, solar or wind energy, then hydrogen power in turn is also not polluting.</span>
