These systems, especially when more distant, often appear to the unaided eye as a single point of light, and are then revealed as multiple by other means.
Answer:
The tertiary protein structure
Explanation:
The primary protein structure consists of amino acids linked by peptide bonds to form a polypeptide chain. The secondary protein structure consists of hydrogen bonding to form an alpha helix/ beta pleated sheet between carboxyl and amino groups of the polypeptide chain. Interactions between the side chain of amino acids are present in the tertiary structure where proteins started folding into it unique conformation.
Explanation:
they are all related to CO2 in a way
The correct answer is option B, that is, functional group.
A functional group refers to a part of a molecule, which is a classified/recognizable group of bound atoms. The functional group provides the molecule with its characteristics, in spite of what molecule comprises it, they are the centers of chemical reactivity. The functional groups in a molecule require to be determined when naming.
