A.) Low frequency and Long Wavelength
Proteins have four structures primary, secondary,m tertiary, and quaternary. The primary structure of the protein has been known to have peptide bonds. Thus, option C is correct.
<h3>What are peptide bonds?</h3>
Peptide bonds are the chemical bonds that are involved in protein polymer formation by linking the amino acid chains. They are also called amide bonds that are present between the nitrogen and the carbonyl atom.
The primary structure of the proteins includes the amino linked by the peptide bonds that make them look like linear structures. The secondary structures have hydrogen bonds and the tertiary have ionic and hydrophilic hydrogen bonds.
Therefore, option C. the primary structure of the protein contains peptide bonds.

Answer:
0.43 mol.
Explanation:
- Knowing that the no. of moles can be calculated using the relation:
<em>no. of moles (n) = mass/molar mass</em>
mass of MgCl₂ = 41.0 g & molar mass of MgCl₂ = 95.211 g/mol.
<em>∴ n = mass/molar mass</em> = (41.0 g)/(95.211 g/mol) = <em>0.43 mol.</em>
