Even though they are classified into different kingdoms, protists and animals share some similar characteristics. Which is an example of a characteristic that algae and a lion have in common?

Eukaryotic

Explanation:

The kingdoms of Protista and Animalia both fit under the general domain of Eukarya, which basically includes all eukaryotic animals. Eukaryotic animals are those whose cells have membrane-bound organelles and a nucleus.

Algae is a type of protist, so clearly it must be eukaryotic. Similarly, lions are part of the Animalia kingdom, so it also must be eukaryotic.

Thus, a common characteristic can be eukaryotic.
