Very few living things survive below which temperature, because of metabolic constraints?
A30 degrees Celsius
B0 degrees Celsius
C4 degrees Celsius
D10 degrees Celsius
Answer & Solution
Correct answer: B. 0 degrees Celsius
1. Temperature exerts an important influence on living things.
2. Few living things can survive at temperatures below 0 degrees Celsius due to metabolic constraints.
3. Therefore organisms must either maintain an internal temperature or inhabit an environment that keeps the body in a workable range.
4. 4 degrees Celsius is where water is densest, which is a different fact.
