Question

how are viruses and bacteria similar? choose one option:
○ they are both types of fungi.
○ they are both living things with cells.
○ they are both treated with antibiotics.
○ they can both cause sickness in humans.

Explanation:

• Option 1: Viruses and bacteria are not fungi. Fungi are a separate group of organisms (e.g., molds, yeasts), so this is incorrect.
• Option 2: Viruses are not considered living things with cells. Viruses are acellular (they lack cells) and rely on host cells to replicate, while bacteria are single - celled living organisms. So this is incorrect.
• Option 3: Antibiotics are ineffective against viruses. Antibiotics target bacterial processes, so this is incorrect.
• Option 4: Both viruses (e.g., influenza virus causing flu, HIV causing AIDS) and bacteria (e.g., Streptococcus causing strep throat, Salmonella causing food poisoning) can infect humans and lead to illness.

Answer:

D. They can both cause sickness in humans.
