It is mobile. It has organ systems. It is made of many cells. It makes its own food.
I gave my students this multiple choice question: A researcher examines a marine organism that is the size of an average human hand. Without more information, which statement about the organism is most likely accurate?

Only one answer is correct among these 4 choices:
- It is mobile.
- It has organ systems.
- It is made of many cells.
- It makes its own food.

Could you tell me which one is correct?

It is made of many cells.
