The answer is (2). The electrolytic cell mechanism is to convert the electrical energy to chemical energy. So it need external energy source. And there is a similar one called voltaic cell which will convert the chemical energy to electrical energy.
Answer:
Human Impacts on the Environment. Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Explanation:
The answer is A) fusion.
