Answer:
Provide a smooth surface at the ends of synovial joints
Explanation:
Cartilage is the smooth elastic tissue that covers and protects the ends of the long bones. This structural component is present in nose and ear. Different types of cartilage are hyaline cartilage, articular cartilage and so on.
Articular cartilage may be defined as a type of hyaline cartilage that are present on the articular surfaces of the long bones. Articular cartilage is present in close association of menisci. This cartilage provides the smooth surface to the synovial joints and bathed in the synovial fluid.

Chronic obstructive pulmonary disease is a life threatening condition in which the lungs gets affected and the ability of the lungs to breathe decreases.
In this case there is a damage in the airways and the tiny air sacs in the lungs. There is an excess of mucus secretion that ultimately hinders the airways causing difficulty in breathing.
The alveoli is also affected as the bronchi oles and alveoli gets narrow which affects the breathing pattern. The inflammation of the air ways also causes the obstruction in the airflow which causes difficulty in breathing.
Hence, the option B, C and D are all the pathophysiology examination of patient suffering from COPD.

Iodine solution is used to test leaves for the presence of starch. You need to: heat a plant leaf in boiling water for 30 seconds (this stops its chemical reactions) heat it in boiling ethanol for a few minutes (this removes most of its colour)
