Explain how these features make it easier for reptiles to live on land:

-Fingers with claws

-Eyes covering the eyes

- Horn scales on the body

- Spongy lungs

Explanation:

1. The presence of fingers with claws makes it easier for reptiles to cling on rough surfaces successfully. An example of this is the Gecko lizard.

2. Eyes covering the eyes of reptiles improves their vision so they can see objects from afar.

3. Horn scales on the body is commonly found in crocodiles, this scales are very helpful in preventing external injury on their bodies.

4. Spongy lungs are necessary for successful respiration, without the spongy nature of the lungs, air (oxygen) passage would be difficult for them.
