B) Decreased blood flow to the skin
C) Dilation of blood vessels in the skin
D) Contraction of muscles
E) Retention of water

Question

Quizplus · Accepted Answer

Decreased blood flow to the skin helps reduce heat loss in marine iguanas when in the water because it minimizes the temperature gradient between the skin and the surrounding water, thereby reducing the loss of heat to the water. This allows the iguanas to maintain their body temperature and conserve energy while swimming in the cold water.
