A metal paper clip would be a conductor since heat energy is easily conducted through metal. If it is off a different material such as plastic it would be a better insulator than a conductor but most paper clips are metal so your answer would be the first sentence.
Active transport uses energy molecules to move particles like sodium, against their concentration gradients, from areas of low concentration to areas of high concentration.
Electrolytes are nothing but minerals that have electric charge when it is mixed in liquid like blood. thus the sodium and potassium electrolytes will help regulate the nerve and muscle function. They also maintain the acid-base balance by regulating the electric charge on the cells and water flow across the membrane.
