The correct answers are:

• Muscular
• Fleshy lobe

Explanation for each option:

1. Muscular: This is correct. Lobe-finned fishes have fins that are supported by a series of bones and muscles, allowing for greater flexibility and movement.

2. No muscles: This is incorrect. Lobe-finned fishes are characterized by having muscles in their fins, which distinguishes them from ray-finned fishes.

3. Fleshy lobe: This is correct. The fins of lobe-finned fishes are fleshy and lobed, supported by a central bone structure.

4. Bony rays at the tips: This is incorrect. While lobe-finned fishes do have bones in their fins, the description of "bony rays at the tips" is more characteristic of ray-finned fishes, not lobe-finned fishes.

In summary, the fins of lobe-finned fishes are muscular and have a fleshy lobe.
