"Surprising" Phenomenon
Why is the chameleon’s tongue extension speed largely unaffected by temperature drops while the weakened muscle power resulting from such drops dramatically slows the chameleon’s tongue retraction speed?
Objective
The right answer will describe a key difference between chameleon tongue retraction and chameleon tongue extension. That difference must explain why tongue retraction speeds decrease dramatically in lower temperatures while tongue extension speeds remain largely unchanged. The answer will likely explain why tongue extension is less impacted than retraction by the muscle weakening chameleons experience in lower temperatures.
