B. atrioventricular (AV) valve
Explanation:
The function of the conduction system of the heart is to spread the electric signal and make the heart contract in coordinated timing. Conduction starts at SA node, then the AV node then will spread by bundle branches.
The atrioventricular valve is not part of the conduction system. The valve function is to keep the blood flow back. If the valve is broken and blood did flow back, it can make the heart need to do more work than usual.
Answer:
The fundamental difference between these compounds is the presence of OH groups in the alcohol that are missing in the ether. Because hydrogen bonds can't form between the molecules in the ether, the boiling point of this compound is more than 80°C lower than the corresponding alcohol.
The protein’s function might be disrupted if the hydrogen bonds break and the protein’s structure will change due to the changes in pH or temperature.
