Which are characteristics of eukaryotic organisms? check all that apply. may be single-celled or multi-celled have cells that contain dna within a nucleus have cells that contain dna in the cytoplasm are always single-celled include plants and bacteria include animals and plants

The correct statements are may be single-celled or multi-celled, have cells that contain DNA within a nucleus and include animals and plants.

Explanation:

There are 2 types of organisms:

1. Prokaryotic organisms: These are teh organisms which does not have membrane bound organelles. They do not contain nucleus. Example: Bacteria

2. Eukaryotic organisms: These are the organisms which can be single celled like protists or can be multi celled organisms like animals and plants. They contain membrane bound cell organelles like mitochondria, nucleus etc.. DNA information is contained in the nucleus only.

From the above information, it is clearly visible that the correct statements are may be single-celled or multi-celled, have cells that contain DNA within a nucleus and include animals and plants.
