Question

The archaea lack which of the following that are normally found in gram-negative bacteria?

• A. outer membrane
• B. a complex peptidoglycan network
• C. they lack both outer membrane and a complex peptidoglycan network
• D. they lack neither outer membrane nor a complex peptidoglycan network

Answer 1

The correct option is C they lack both outer membrane and a complex peptidoglycan network

Gram-positive bacteria lack an outer membrane but are surrounded by layers of peptidoglycan many times thicker than is found in the Gram-negatives.
