Answer 2

The platypus lays eggs like a reptile.

Explanation

Some of the common characteristics of mammals are as follows:

1. They are endothermic.

2. They are vertebrates.

3. They have a four-chambered heart.

4. They have hair and fur on their bodies.

5. They have mammary glands.

Some of the common characteristics of reptiles are as follows:

1. They lay eggs.

2. They are vertebrates.

3. They have scales present on their bodies.

4. They are ectothermic.

Based on this, it can be seen that laying eggs is a characteristic of reptiles and thus, the information that platypus although is a mammal but lays eggs like a reptile would help her to construct the tree in a better way.
