Secondary structures are stabilized by which type of interaction?
Brrunno [24]
This pertains to the structure of proteins. Secondary structures are stabilized by the presence of hydrogen bonds. The common types of secondary structures of proteins are the alpha helix and the beta sheets, each performing different functions. 

Primary structure of protein is the peptide molecule comprised of peptide bonds. Once these peptide grows long enough, it will either be arranged into alpha helices or beta sheets stabilized by hydrogen bonds and this is the secondary structure. Once there is protein folding involved in the secondary structure of protein, then the folded protein is called the tertiary structure (or a protein subunit). When protein subunits come together to perform a specific function, then that is the quaternary structure.

Attached is a figure concerning the protein structures.

mash [69]

Answer:

C. Large, deep body of water that contains fresh water

Explanation:

Keywords in question: "Freshwater wetland"

Answer A does not have those keywords in the answer. It does not talk about water, it talks about acidic areas!

Answer B does talk about water, but it's not specifically saying anything about freshwater. It talks more about the landscape of the area feeding water into rivers.

Answer C says fresh water at the end of the answer. It's telling you that the body of water contains fresh water. So, this phrase does describe the qualities of fresh water wetland.

Hope this helps you! :3
