The correct statement that describes a difference between a jellyfish and a frog is:
A jellyfish lacks vertebrae, whereas a frog has a spinal cord.
This is true because jellyfish are invertebrates, meaning they do not have a backbone, while frogs are vertebrates that possess a spinal column.
The other statements contain inaccuracies:
- Jellyfish can reproduce both sexually and asexually.
- Jellyfish do not make their own food (they are heterotrophs), so both are heterotrophs.
- Both jellyfish and frogs are eukaryotes, as they are made up of complex cells with a nucleus.
