Question

1. why are antibiotics ineffective against fungal infections?

fungal cells have more in common with animal cells than bacterial cells.
fungal cells are too small for antibiotics to affect.
fungal cells do not reproduce.
fungal cells do not have dna.

Explanation:

• Analyze Option 1: Fungal cells (eukaryotic) share more cellular features (like having a nucleus, membrane - bound organelles) with animal cells (eukaryotic) than with bacterial cells (prokaryotic). Antibiotics are designed to target bacterial cell structures/processes (e.g., cell wall synthesis in bacteria) that are different from fungal and animal cells. So, antibiotics that target bacterial - specific features won't work on fungi as fungi don't have those bacterial - like targets.
• Analyze Option 2: Fungal cells are not too small for antibiotics to affect. Antibiotics can act on cells of various sizes as long as the target structures/processes are present.
• Analyze Option 3: Fungal cells do reproduce (e.g., through spores, budding), so this statement is false.
• Analyze Option 4: Fungal cells do have DNA (they are eukaryotic cells with a nucleus containing DNA), so this statement is false.

Answer:

A. Fungal cells have more in common with animal cells than bacterial cells.
