Explanation:
Starfish, also known as sea stars, are marine organisms that belong to the Class Asteroidea. They are considered invertebrates because they lack a vertebral column. Moreover, most starfish species have five arms but some species can have up to 15!
Here are some characteristics that differentiate starfish from other organisms and make them so unique:
- Possession of tube feet.
- Most species have pedicellaria, claw-shaped structures with movable jaws.
- Radial symmetry
- They can possess from 5 to 15 arms.
- Do not possess brain.
- They can regenerate parts of their body.
I would say either C or D beside A say most living things are made of cells. No, all living things have cells. And B is right but C or D makes more sense.
