INBDE (Integrated National Board Dental Examination) Practice Exam

Beta hemolysis is the complete lysis of red blood cells in media, while the other options (Alpha, Gamma, Delta) represent partial lysis of the cells. This means that in Alpha, Gamma, and Delta hemolysis, some of the red blood cells remain intact, whereas in Beta hemolysis, all of the cells are broken open and destroyed. Therefore, Beta hemolysis is the only correct answer and the others are incorrect.
