For each of the traits described below, indicate if it is true only in archaea, only in bacteria, in both archaea and bacteria or in neither group.

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. - 

4) They have mitochondria. - in neither group

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

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
