b. Domains are stable because they conserve their tridimensional structure in physiological conditions even if they are separated of the rest of the protein.

c. The ß-barrel motif is a type of motif localized in single-stranded DNA viruses.

d. Calmodulin is a protein that contains calcium-binding motifs that enable to sense intracellular calcium levels.

e. Domain folding patterns are critical transitional states that allow the proteins their interaction with specific ligands in different physiological conditions.

f. Motifs are sometimes independently stable, but due to their short length (3-15 amino acids), protein motifs are generally unstable in different conditions.
