b. Include chemoautotrophs and chemoheterotrophs.
c. Histones are present, and are very similar to those of eukaryotes.
d. Membrane lipids are branched and contain ether linkages.

a. Cell walls lack peptidoglycan. True for archaea but not bacteria

b. Include chemoautotrophs and chemoheterotrophs.
True for Archaea: chemoautotrophs that use bacteriorhodopsin are purple Halobacteria and the Epsilonproteobacteria while Halobacterium salinarum are chemoheterotrophs.
True for Bacteria: Nitrifying bacteria are chemoautotrophs while Lactobacillus are chemoheterotrophs

c. Histones are present, and are very similar to those of eukaryotes.
Histones are not found in bacteria, this is only true in Archaea & Eukarya.
