Question

When a frog is transferred from ${20}^o$C to ${30}^o$C, its body temperature ________________.

• A. Falls to ${15}^o$C
• B. Rises to ${30}^o$C
• C. Falls to ${12}^o$C
• D. Remain unchanged

Answer 1

The correct option is B Rises to ${30}^o$C

Frogs are ectothermic. Ectotherms depend mainly on external heat sources and their body temperature changes with the temperature of the environment. So, the temperature rises to 30°C as the external environment temperature.

So, the correct option is B.
