The statements that apply only to a eukaryotic cell and not to a virus are:
D. A eukaryotic cell contains structures to produce and use energy. E. A eukaryotic cell responds to its environment.
Here's a brief explanation for each:
-
D. A eukaryotic cell contains structures to produce and use energy.: Eukaryotic cells contain organelles such as mitochondria that are responsible for energy production, which viruses do not have.
-
E. A eukaryotic cell responds to its environment.: Eukaryotic cells have mechanisms to respond to environmental stimuli, whereas viruses do not possess the biological machinery to respond to their environment independently.
The other options either pertain to both eukaryotic cells and viruses or do not accurately describe eukaryotic cells alone.
