The four levels of protein structure are distinguished from one another by the degree of complexity in the polypeptide chain. A single protein molecule may contain one or more of the protein structure types: primary, secondary, tertiary, and quaternary structure. 1. Primary Structure: describes the unique order in which amino acids are linked together to form a protein.
2. Secondary Structure: refers to the coiling or folding of a polypeptide chain that gives the protein its 3-D shape. There are two types of secondary structures observed in proteins. One type is the alpha (α) helix structure. This structure resembles a coiled spring and is secured by hydrogen bonding in the polypeptide chain. The second type of secondary structure in proteins is the beta (β) pleated sheet. This structure appears to be folded or pleated and is held together by hydrogen bonding between polypeptide units of the folded chain that lie adjacent to one another
3. Tertiary Structure: refers to the comprehensive 3-D structure of the polypeptide chain of a protein.
4. Quaternary Structure: is the structure of a protein macromolecule formed by interactions between multiple polypeptide chains. Each polypeptide chain is referred to as a subunit. Proteins with quaternary structure may consist of more than one of the same type of protein subunit.
Answer:
Dispersion of white light by a prism
Explanation:
When white light is passed through a prism, the white light separates into its component wavelengths which are:
Red
Orange
Yellow
Green
Blue
Indigo
Violet
Together, all of these wavelengths constitute the spectrum of white light.
Hence, the dispersion of white light shows that each color of visible light has a specific wavelength.
Some plants also have large leaves to soak up nutrients and water, very helpful in this biome since it rains a lot. - Having some needles cased in wax, withstand cold temperatures and losing water from their leaves. - Having thin bark and shallow roots enables trees to withstand fire.
