Lizard Skin
Posted on Tuesday, February 9, 2010 in Bike Parts
The chameleon is a kind of lizard which can change both the colour and pattern of its skin very rapidly.?
a) Explain whether hormonal control or nerve control is more likely to be involved.
b) Suggest how this feature helps control the internal temperature of the animal.
a) It is more likely nerve control. It would be impossible to control the intricate patterns with hormones flowing in the blood.
b) When it is cool it darkens it's skin to absorb more heat from the sun and when it is too warm it lightens it's skin to reflect heat.
I am assuming we are talking about true chameleons and not anoles.
