Which of the Conditions Can Be Labeled as "Extreme

Question

Which of the conditions can be labeled as "extreme"?
A) near-neutral pH
B) 25°C
C) pressure of 400 atm
D) a salt concentration of 0.9%
E) pressure of 14 psi

Accepted Answer

A pressure of 400 atm is considered extreme as it is much higher than normal atmospheric pressure (14.7 psi) and can have a significant impact on the behavior of gases and liquids. The other conditions listed fall within normal ranges or are close to optimal conditions for biological processes.
