32) The composition of cell wall of both gram positive and gram negative bacteria are different. The gram negative bacteria consists of lipopolysaccharide (LPS) in its cell wall while techoic acids are found in the cell wall of gram positive bacteria. So, the correct statements are A and D.
33) The substance that is found in archae but not in bacteria is S-layer.
