Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are viruses and bacteria alike?
A
Both viruses and bacteria need a host cell to reproduce.
B
Both viruses and bacteria do not have a nucleus or membrane-bound organelles.
C
Both viruses and bacteria have a nucleus and membrane-bound organelles.
D
Both viruses and bacteria can be killed by antibiotics.
Explanation: 

Detailed explanation-1: -All living things, including plants, animals, and microbes like bacteria and archaea, are susceptible to virus infection. There is no nucleus in a virus. Many typical cell components, like the mitochondria, nuclei, and even the ribosome, are absent in viruses. Even some of these viruses are cytoplasm-free.

Detailed explanation-2: -Bacteria do not have a well defined nucleus. Since the nucleus contains DNA, it can be concluded that bacteria do not contain DNA.

Detailed explanation-3: -Viruses do not have organelles or a nucleus. Viruses rely on their host cells to replicate and make new viral particles. eukaryotes: contain a nucleus that is enclosed by a plasma membrane.

Detailed explanation-4: -Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do. However, photosynthetic bacteria, such as cyanobacteria, may be filled with tightly packed folds of their outer membrane.
