A nonopeptide contains………….peptide linkages.

Explanation

To determine the number of peptide linkages in a nonapeptide, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Peptide Linkages**: A peptide linkage (or bond) is formed between two amino acids when they undergo a condensation reaction, resulting in the elimination of a water molecule (H2O).

2. **Identifying the Structure of a Nonapeptide**: A nonapeptide is a peptide that consists of nine amino acids.
