Question

use the text to compare and contrast baleen whales and toothed whales.
whales are classified into two major groups, depending on whats inside their mouths. toothed whales have teeth that they use to catch food from the ocean. but instead of teeth, baleen whales have plates that filter water out of their mouths and trap krill inside. the physical features and habits of these whales differ in other respects, too. baleen whales have symmetrical skulls, which means their skulls are balanced in size and shape. toothed whales, however, have asymmetrical skulls. baleen whales have two blowholes and large tongues, while toothed whales have only one blowhole each and small tongues. toothed whales live in complex social groups and use echolocation, a process of using sound waves to hunt and navigate. by contrast, baleen whales live in small groups and most likely do not use echolocation.

	baleen whales	toothed whales
have one blowhole
have large tongues
live in small groups
use echolocation

Explanation:

To solve this, we analyze the text for each characteristic:

1. Have symmetrical skulls

• From the text: "Baleen whales have symmetrical skulls... Toothed whales, however, have asymmetrical skulls."
• So: Baleen whales ✔️, Toothed whales ❌

2. Have one blowhole

• From the text: "Baleen whales have two blowholes... Toothed whales have only one blowhole each."
• So: Baleen whales ❌, Toothed whales ✔️

3. Have large tongues

• From the text: "Baleen whales have... large tongues, while toothed whales have... small tongues."
• So: Baleen whales ✔️, Toothed whales ❌

4. Live in small groups

• From the text: "Baleen whales live in small groups... Toothed whales live in complex social groups."
• So: Baleen whales ✔️, Toothed whales ❌

5. Use echolocation

• From the text: "Toothed whales... use echolocation... Baleen whales... most likely do not use echolocation."
• So: Baleen whales ❌, Toothed whales ✔️

Filling the table:

	Baleen whales	Toothed whales
Have one blowhole	❌	✔️
Have large tongues	✔️	❌
Live in small groups	✔️	❌
Use echolocation	❌	✔️
