Answer:
Substances that conduct an electric current only under certain conditions are most likely to be METALLOIDS
Explanation:
Metalloids conducts electricity and allows the passage of electron which enhances their conductivity and make them suitable for it. Although this ability is only achieved when there is an increase in temperature in order to achieve this feat.
It's a chemistry question why is it in biology?
