Question

Which of the following in INCORRECT about conformers?

• A. They cannot maintain a constant internal environment.
• B. Their body temperature changes with ambient temperature.
• C. They perform physiological changes to ensure constant body temperature.
• D. When acquatic, they change osmotic concentration of body fluids as per ambient water osmotic concentration.

Hint:

Conformers = environment-dependent. Regulators maintain constant internal conditions.

Answer 1

The Correct Option is C

Concept:
Conformers are organisms that cannot regulate their internal environment and depend on external conditions.

Step 1: Understand conformers.
• Cannot maintain constant internal conditions
• Body temperature varies with surroundings
• No active thermoregulation

Step 2: Analyze statements.
• (A) Cannot maintain internal environment → Correct \checkmark
• (B) Body temperature varies → Correct \checkmark
• (C) Maintain constant body temperature → Incorrect $\times$
• (D) Osmotic concentration varies with environment → Correct \checkmark

Step 3: Conclusion. \[ \text{Incorrect statement = They maintain constant body temperature} \]
