characteristics of animals
always\tsometimes

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

Explanation:

• All animals are multicellular, so this belongs in "Always".
• All animals are eukaryotes, meaning they always have membrane-bound organelles, so this belongs in "Always".
• Animals are heterotrophs, so they never produce their own food.
• Most animals have symmetrical body plans (radial or bilateral), but some rare animals (like sponges) have an asymmetrical body plan, so this is a characteristic that applies "Sometimes".

Answer:

Display an asymmetrical body plan
