I found the full exercise on the internet. Below are the traits and answer:

1) The cells do not contain ribosomes. - both archaea and bacteria

2) Most of the microorganisms in the group have a cell wall. - both archaea and bacteria

3) When proteins are being made, the first amino acid is a methionine. -

only in archaea (in bacteria is a derivate of it N-formylmethionine)

4) They have mitochondria. - in neither group

5) The fatty acids found in the cytoplasmic membrane have branching chains. only in archaea (f atty acids in bacteria have straight chains)
