All proteins have a primary structure. fibrous and globular proteins have a secondary structure: α helix or β pleated. globular proteins also have a tertiary structure due to interactions of amino acid side chains with water. most globular proteins, including hemoglobin also have a quaternary structure. which of these structures is due to h bonding between amino acid chains?

The correct answer is secondary structure of proteins is formed by the hydrogen bonding between amino acid chains.

Explanation:

The secondary structure of protein is generally stabilized by peptides bond along with hydrogen bonding between hydrogen atom and an electronegative atom such as oxygen.

     The secondary structure both alpha helix and beta pleated sheet are stabilized by hydrogen bonding beside the presence of peptide bonds.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
