EUKARYA

Question 20

DOMAIN OF LIFE

(with peptidoglycan) includes all of the pathogenic prokaryotes as well as many of the nonpathogenic prokaryotes found in soil and water and the photoautotrophic prokaryotes

Answer 20

BACTERIA

Question 21

DOMAIN OF LIFE

(prokaryotes that do not have peptidoglycan in their cell walls. ). They often live in extreme environments and carry out unusual metabolic processes.
