Some of the symptoms of MLS incude: 1  Small eye. 2  Sclerocornea. 3  Dermal aplasia. 4  Midfacial hypoplasia. 5  Linear erythematous skin lesions.
Best Answer: A. GFCI is the correct answer. Ground Fault Circuit Interruptor: This will open the circuit when a difference in current is detected between the hot and neutral wires in a 120VAC (House current) circuit. B Circuit Breaker will only open the circuit on the hot side when a maximum current is reached. C. Blows open when a maximum current is reached in one line.
The combination electrode measures the difference in potentials between the two sides in the glass electrode. To measure the potentials it must be a closed circuit. The circuit is closed through the internal solutions of the electrode and the external solution that is being measured and the pH meter. As the electrode is immersed in the test solution the glass bulb senses the hydrogen ions as a millivoltage due to the positive charge of the hydrogen ions.
