Based on the information provided, let's evaluate each statement:
1. **Sharks have more of the traits shown than of all of the other organisms.**
- This statement is likely **incorrect**. Sharks, as fish, do not share traits such as hair or four limbs that are found in other groups mentioned (like mammals and amphibians).
2. **Rodents and Rabbits do have Eggs with Shells.**
- This statement is **incorrect**. Rodents and rabbits are mammals, and they do not lay eggs; they give live birth.
3. **Sharks and Primates do not have a common ancestor.**
- This statement is **incorrect**. All vertebrates, including sharks and primates, share a common ancestor in the distant evolutionary past.
4. **Birds have all of the shown traits that Sharks have, but Sharks do not have all of the shown traits that Birds have.**
- This statement is **correct**. Birds have traits like bony skeletons and vertebrae, which sharks also possess. However, sharks do not have traits like feathers or the ability to regulate their body temperature like birds do.
5. **Crocodiles and Amphibians are more closely related than Birds and Sharks.**
- This statement is **correct**. Crocodiles and birds share a more recent common ancestor (as they are both part of the archosaur group), while sharks are distant relatives compared to these other groups.
So, the correct answers are:
- Birds have all of the shown traits that Sharks have, but Sharks do not have all of the shown traits that Birds have.
- Crocodiles and Amphibians are more closely related than Birds and Sharks.
