Answer the following question given this paragraph: Four interactions stabilize the tertiary structure of a protein: (a) ionic bonding, (b) hydrogen bonding, (c) disulfide linkages, and (d) dispersion forces. When a protein contains more than one polypeptide chain, each chain is called asubunit. The arrangement of multiple subunits represents a fourth level of structure, the quaternary structure of a protein. Hemoglobin, with four polypeptide chains or subunits, is the most frequently cited example of a protein having quaternary structure Saylor URL: http://www. saylor. org/books. Q: Hemoglobin, with four polypeptide chains or subunits, is the most frequently cited example of a protein having what kind of structure? Choices: - binary - unary - ternary - quaternary A:

Q: Answer the following question given this paragraph: Most adults experience at least some hearing loss as they get older. The most common cause is exposure to loud sounds, which damage hair cells. The louder a sound is, the less exposure is needed for damage to occur. Even a single brief exposure to a sound louder than 115 decibels can cause hearing loss. Figure below shows the relationship between loudness, exposure time, and hearing loss. Q: Because it damages hair cells, what is the most cause of hearing loss in adults? Choices: - bacteria - ear wax - water in the ears - exposure to noise A:
A: exposure to noise
