If these were the choices:
A. modeling an ocean ecosystem with a saltwater aquarium
<span>B. observing the behavior of male caribou on the arctic tundra </span>
<span>C. using dissection to study the general structure of lily flowers </span>
<span>D. growing algae in different environments found on a spacecraft
</span>
Then, my answer would be C. USING DISSECTION TO STUDY THE GENERAL STRUCTURE OF LILY FLOWERS.
Other choices are very hard to do. Maintaining a salt-water aquarium is very hard while going to an arctic tundra or space is impractical.
