A research laboratory is investigating environmental factors that would inhibit the growth of Archaea. One question they have is if adding the antibiotic penicillin would be effective in controlling their growth. What do you think the outcome would be if they tried this?

  1. The penicillin wouldn't affect the Archaea because it prevents crosslinking of peptidoglycan-Archaea don't have this compound in their cell walls.

  2. The penicillin will inhibit cell wall formation in the Archaea, killing them.

  3. The penicillin will slow down the growth of the Archaea by damaging the cell wall, but they will still be able to grow somewhat.

  4. The penicillin will enhance the growth of the Archaea by providing a rich nutrient source.
