The correct comparison from the options provided is:
A eukaryotic cell responds to changes in the environment, whereas a virus cannot adapt.
Explanation: Eukaryotic cells are complex cells that can respond to stimuli and adapt to their environment, while viruses lack cellular structure and cannot respond independently to environmental changes. However, some of the other statements are partially correct but not entirely true.
- It's important to note that a eukaryotic cell contains genetic material, whereas a virus does contain genetic material (either DNA or RNA) but not in the form of cellular DNA.
- A eukaryotic cell can reproduce to make more cells, but a virus cannot reproduce on its own; it requires a host cell to replicate, which makes the original statement slightly misleading.
- Homeostasis is a process that involves maintaining a stable internal environment, which eukaryotic cells can do, but the statement about viruses lacking required organelles is a bit off as they are not classified as cellular organisms to begin with.
So, while the first choice is the most accurate in comparing their responses to stimuli, the others include inaccuracies regarding their genetic material and reproduction methods.
