Answer:
a neutral charge
Dad I'm so taking electron so it would be a neutral charge because it will do something
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.

Explanation:
Daytime temperatures are often around 70°F (25°C) and occasionally 80°F (30°C) at lower elevations. Nights are usually cool and temperatures may drop below freezing at higher elevations.
I believe the correct answer from the choices listed above is option A. When a system is in dynamic equilibrium, the input of the system is equal to <span>the output of the system. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
