Question

which trait describes all animals? animals can make their own food. animals are made up of one cell. animals have cells that have a nucleus.

Explanation:

• Organisms that make their own food are autotrophs (like plants); animals are heterotrophs, so the first option is incorrect.
• Animals are multicellular; only single-celled organisms (like bacteria or some protists) are made of one cell, so the second option is incorrect.
• All animals are eukaryotes, meaning their cells contain a nucleus enclosed by a membrane, which is a universal trait for animals.

Answer:

Animals have cells that have a nucleus.
