Question：
Using the example of the mole, explain two different types of underground adaptation.
Sample answer：
The professor talks about two physical adaptations of mole for living underground. One adaptation is used to deal with the challenge to move underground. Moles have wide super strong front feet with big claws that allow moles to dig through the dirt and so to move through thick, dense soil efficiently. Using the shovel-like front feet, the mole loosens up the soil and throw the dirt behind as it moves forward. Another adaptation is used to protect their sensitive parts of body. Moles have developed the hairy membrane on their tiny eyes. The hairy membrane can prevent particles from going into moles’ eyes, the most sensitive parts. And So when mole is digging through the dirt, dirt particles will just slide by its eyes.
