which two characteristics do all animals have?\no they are symmetrical and heterotrophic.\no they are heterotrophs and have a backbone.\no their cells have a nucleus and membrane - bound organelles.\no they have a backbone, and their cells have membrane - bound organelles.

Answer

Brief Explanations:

All animals are eukaryotes, meaning their cells have a nucleus and membrane - bound organelles. Also, animals are heterotrophs as they obtain energy by consuming other organisms. Not all animals are symmetrical (e.g., sponges), and not all have a backbone (invertebrates).

Answer:

Their cells have a nucleus and membrane - bound organelles.
