Question

It can be said that some animals in their evolutionary development preferred to be conformers than regulators. Which of the following can be the best suited reason for it ?

• A. The metabolic reactions of these organisms can occur at a very wide range of temperature
• B. Maintaining homeostasis is an energetically expensive process
• C. The enzymes of these organisms are functional at high temperatures
• D. Both (b) and (c)

Answer 1

Answer: (B)

Maintaining homeostasis, especially thermoregulation is energetically expensive for many organisms. During the course of evolution, the costs and benefits of maintaining a constant internal environment were taken into consideration and thus some species preferred to be conformers.
