Identify if the statement is True or False. If the statement is false, identify what is incorrect and correct it.  1. Liquefactive necrosis is a pattern of cell death characterized by dissolution of necrotic cells (example: abscess) 2. Electrons are frequently added to O2 to create biologically important ROS (.OH, H2O2 and O2-). Free radical is unpaired electron which makes the atom or molecule less reactive. DNA damages can lead to cell severe injury, and apoptosis. An improperly folded proteins can also initiate apoptosis. 3.
