Explanation: Solar power is an example of renewable energy. Renewable energy sources are those that can be replenished naturally or through human intervention, making them sustainable in the long term. Solar power harnesses energy from the sun using photovoltaic cells or solar thermal systems, and it can be converted into electricity or used for heating purposes. Natural gas and coal are non-renewable fossil fuels, and nuclear power relies on the use of radioactive materials, which are finite resources.

   anation: One of the functions of the mineral sodium in the body is mu action and nerve transmission. Sodium plays a crucial role in maintai balance and facilitating the transmission of nerve impulses. It works gside other electrolytes, such as potassium, to regulate the electrical ges across cell membranes, enabling proper muscle function and nerve aling. Sodium is not directly involved in immune system function or t ation of red blood cells. Therefore, option A is the correct answer.
