General Biology

What happens when a penguin's body temperature drops too low?

• Blood vessels dilate to release heat

• The penguin starts shivering to generate warmth

• The penguin spreads its flippers to cool down

• The penguin stops moving completely

Which of the following is an example of positive feedback in penguins?

• Blood vessel constriction to conserve heat

• Penguins huddling together for warmth

• Slowing down metabolism to conserve energy

• Panting to release excess heat
