Question

which characteristic most likely describes a mushroom but not thermus aquaticus?
cell wall
eukaryotic
unicellular
prokaryotic

Explanation:

1. Cell wall: Both mushrooms (fungi) and Thermus aquaticus (a bacterium) have cell walls, so this is not a distinguishing feature.
2. Eukaryotic: Mushrooms are fungi, which are eukaryotic organisms (they have a membrane-bound nucleus and organelles). Thermus aquaticus is a bacterium, which is prokaryotic (no membrane-bound nucleus). This is a unique characteristic of mushrooms compared to the bacterium.
3. Unicellular: Thermus aquaticus is unicellular, while mushrooms are multicellular, so this describes the bacterium, not the mushroom.
4. Prokaryotic: This describes Thermus aquaticus, not the eukaryotic mushroom.

Answer:

eukaryotic
