Brendan made a chart to categorize the characteristics of animals.

Question

An empty 2-column table titled Characteristics of Animals. Column 1 is labeled Always. Column 2 is labeled Sometimes.

Which phrase should be written in the column titled "Sometimes”?

Are multicellular
Have membrane-bound organelles
Produce their own food
Display an asymmetrical body plan

Answer 1

The phrase that should be written in the column titled "Sometimes" is "Display an asymmetrical body plan."

This is because not all animals exhibit an asymmetrical body plan; some are symmetrical (e.g., bilateral or radial symmetry), while others may display asymmetry only at certain life stages or forms. The other options listed (multicellular, having membrane-bound organelles, and producing their own food) are characteristics that are generally true for all animals or specific categories of them.
