Bаcteriа аre оften classified by their cell wall cоmpоsition using the Gram stain method. Gram-positive bacteria possess a thick layer of peptidoglycan, a carbohydrate polymer that is a common target for antibiotics. In contrast, Gram-negative bacteria have a much thinner peptidoglycan layer and an additional outer membrane.Scientists tested the efficacy of Antibiotic X, a drug designed to disrupt peptidoglycan synthesis, on three different samples:Sample 1: Staphylococcus aureus (Gram-positive bacteria).Sample 2: Escherichia coli (Gram-negative bacteria).Sample 3: A biofilm of S. aureus, which is a community of bacteria encased in a protective matrix.The results of the "Zone of Inhibition" test (where a larger zone indicates the antibiotic is more effective at killing the bacteria) are shown in Figure 1.Figure 1 | Bacterial Sample | Zone of Inhibition (mm) | | Sample 1 (S. aureus) | 24 | Sample 2 (E. coli) | 11 | Sample 3 (S. aureus Biofilm) | 5 |1. Based on the passage and Figure 1, which of the following statements best explains why Sample 1 had a larger zone of inhibition than Sample 3?
