The correct statement that accurately compares a eukaryotic cell and a virus is:
a A eukaryotic cell maintains homeostasis, whereas a virus does not possess the required organelles.
This statement highlights the fundamental differences between eukaryotic cells and viruses, particularly regarding homeostasis and organizational complexity.
While statements b and c are partially correct, they can be misleading without context. For example, viruses can reproduce, but only within a host organism, and although viruses do not "adapt" in the same way living organisms do, they can undergo mutations that can lead to changes over time.
Statement d is incorrect because viruses do contain genetic material, either DNA or RNA, contrary to what this option states.
