I think you just answered your question. They encourage adolescents to eat calcium-rich foods because it aids in bone formation, like you said.
Answer:
Secondary level of protein structure
Explanation:
The proteins are formed of the monomer units called amino acids which bond with each other via peptide bond and form a linear peptide structure called the primary level structure of the protein.
The proteins to perform several functions in a cell undergoes structural conformation and attain the helical form called alpha helix due to the involvement of alpha carbon in bond formation and a pleated sheet called beta-pleated sheet due to the involvement of beta carbon. These structures are known as a secondary level of protein structure.
Thus, a Secondary level of protein structure is the correct answer.

There are so many changes due to adaptation and climate change
The principal components of the plasma membrane are lipids, proteins, and carbohydrate groups
