Question 9 • Science 7 B (M12 25/26 S2)

Which statement accurately contrasts archaebacteria with eubacteria?

Answer
A
Only archaebacteria live in the human body.
B
Only archaebacteria can live in extremely salty waters.
C
Only eubacteria live in the human body.
D
Only eubacteria can live in extremely salty waters.

Explanation

Some archaebacteria, called extreme halophiles, can survive in extremely salty waters. Eubacteria do not have this distinctive ability, so “Only archaebacteria can live in extremely salty waters” is the accurate contrast. Both groups include organisms that can live in or on the human body, so choices A and C are not correct.
