4. Macromolecules with multiple polypeptides form globular or fibrous protein structures (quaternary structure)
Answer:
For the K category it wants you to fill in background information, for example, if you chose the Artificial Heart article. Have you read any stories or seen any movies about this topic?

Answer:
Both are breathing muscles
Explanation:
When rib muscles and the diaphragm contract they increase the volume of the chest cavity, increasing the air pressure outside the body, causing air to rush into the lungs to fill the vacuum created by the increase in volume.
Fatigue in skeletal muscles typically develops during repeated shortening contractions, as during walking or running. However, most experimental fatigue studies have analysed isometric muscle contractions, were the muscle generates force at a constant length.
