Answer:
False
Explanation:
All bacteria contain peptidoglycan in the their cell wall; the major component of peptidoglycan is the N-acetylmuramic acid. The peptidoglycan in bacteria helps to protect the bacteria plasma membrane and cell as a whole from environmental stress as well as maintaining its cell morphology.
In this case, the unicellular organism that was discovered is most likely an archaea. Archaea are organisms that have a semi rigid cell wall with the absence of peptidoglycan.

When the continents separated, organisms were forced to be placed in different locations with different environmental conditions. In order to survive in their new environment, over time, various flora and fauna developed various body mechanisms to cope up. This brought up the speciation of flora and fauna.
Carbon dioxide moves out of the tissues (cells) into the bloodstream to be exhaled in internal respiration.
