Final answer:
The correct order of body structures that respond to changes in environmental conditions such as temperature is cell, tissue, organ, organ system, organism.
Step-by-step explanation:
The correct order in which body structures would respond to changes in environmental conditions such as temperature is: cell, tissue, organ, organ system, organism.
When the temperature changes, individual cells will respond first by adjusting their internal processes. Then, tissues made up of similar cells will work together to respond to the change. Organs are made up of different tissues and will also respond to the change. The organ system is a group of organs that work together to perform a specific function and will also react to the temperature change. Finally, the organism as a whole will respond and adapt to the new temperature.
