To determine which organisms Peyton would draw on the same branch of her cladogram, we need to consider their evolutionary relationships.
1. **Whale and water boatman**: These two organisms are from very different classes (mammals and insects) and do not share a recent common ancestor, so they would not be on the same branch.
2. **Praying mantis and whale**: These also belong to different classes and do not have a close evolutionary relationship, so they would not be on the same branch.
3. **Praying mantis and cat**: These organisms are from different classes as well (insects vs. mammals) and do not share a recent common ancestor.
4. **Praying mantis and water boatman**: Both praying mantises and water boatmen are insects and are more closely related than to whales or cats, so they could share a more recent common ancestor.
Given these relationships, the correct answer is:
**d) praying mantis and water boatman**
They would be drawn on the same branch of the cladogram, indicating they have a more recent common ancestor compared to the other pairs listed.
