Which process occurs at the anode in an electrochemical cell?
(1) the loss of protons
(2) the loss of electrons
(3) the gain of protons
(4) the gain of electrons

The process that occurs at the anode in an electrochemical cell is the loss of electrons. The answer is number 2. Oxidation occurs as electrons are lost at the anode at one of the electrodes in both an electrolytic cell and a voltaic cell.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
