The matching of the structure of proteins is as follows:
- Primary structure: Linear polypeptide chain.
- Secondary structure: Twisted polypeptide chain.
- Tertiary structure: Folded polypeptide chain.
Thus, the correct option is A.
<h3>What are Proteins?</h3>
Proteins may be defined as intrinsically appearing, a remarkably complicated substance that consists of amino acid residues united by peptide bonds.
The primary structure of the protein is so simple and it looks like a linear chain of the polypeptide. The secondary structure of proteins consists of alpha-helix and beta-pleated sheet that involves the twisted form of polypeptide chains.
The tertiary structure of the protein is more complicated as compared to secondary and primary. This structure emerges due to the constant folding of polypeptide chains.
Therefore, it is well described above.

Answer:
FALSE is correct
Explanation: Questions protected!
Answer: sand particles, small pebbles and weathered rock
Sedimentary rocks are the rocks that are formed by various physical, chemical, and biological processes. It is formed by the withered remains of the other rocks, biological wastes liberated by the living beings. These rocks are formed when the fine sand particles, stones, small pebbles and biological residues of living beings becomes cluster and attains compaction due to the effect of exerted pressure and temperature.
