    2. BFalso
34. 34Difference between gram + and gram - bacteria
    
    This is due to the difference in the structure of their bacterial cell wall. Gram-positive bacteria do not have an outer cell membrane found in Gram-negative bacteria. The cell wall of Gram-positive bacteria is high in peptidoglycan which is responsible for retaining the crystal violet dye.

    2. BFalso
71. 71Vaccines work by an inactivated or weakened disease-cauing microorganism (virus or bacteria) is introduced to the immune system. Immune cells of the adaptive system recognise a potential threat and elicit an immune response - comprising of the production of antibodies and memory cells. Future encounters with the same disease-causing microorganism will be target and destroyed.
