Answer:

C) Primary, tertiary and quaternary levels of protein structure

Explanation:

Primary structure; Covalent bond is present in form of peptide bond in the primary structuture of proteins. The amino acids are held together in the polypeptide chain by peptide bond.

Tertiary structure; Disulfide bonds are present between cysteine amino acids, that keeps the parts of polypeptide chain strongly attached to one another.

Quaternary structure; The Quaternary structure of protein is held together by hydrophobic interaction and disulfide bonds.

Kryger [21]

It is the discomfort, inferiority, embarrassment, rejection, and disapproval we experience in our own skin when witnessing an act that we find repugnant, reprehensible, or pathetic on the part of another person.

<h3>Why is it that everything makes me cringe?</h3>

Cringe, according to developmental psychologist Phillipe Rochat, is an innate empathetic reaction of either scorn or compassion. One cannot cringe without having experienced the discomfort of an embarrassing situation, which is a requirement for an empathy reaction.

<h3>The cringe: How do you handle it?</h3>

You could do the following if you're cringing and criticizing yourself: resisting the want to recall the embarrassing situation. to divert your attention from the memories, engage in something else. telling yourself that what happened wasn't so bad or that nobody cares, so there's no reason for you to feel bad.
