How do you analyze statement 2? Thank you.
Those parts are thinner in thickness and size relative to the torso and the scull, thus more exposed to the cooling air. They are also further away from the warmer blood which is found nearest to heart than in distal areas of the body and extremities. The thickness of blood vessels is also lower in those areas than the the main arteries of the body.
Cooler areas activate the gene in the cells of those cool areas.
H would be the answer.
