As blood enters the artery, the walls of these vessels expand and contract, which can be felt as the pulse where the arteries run close to the body surface.
It is common to detect the pulse with a few fingers placed on the radial artery on the wrist, or the carotid artery in the neck.
Because the walls of the arteries pulse whenever the left ventricle contracts, the pulse rate generally indicates the cardiac function, which is normally between 50 and 85 in a healthy adult.
Pulse is usually defined as the rhythmic dilation of the arteries due to flow of the blood caused by heart contractions. The measurement of the pulse rate can be used for the diagnosis of serious disease such as cardiac disease.

Answer:
Substitution mutation is a type of mutation which is responsible for sickle cell anemia disease.
Explanation:
Substitution mutation is also called point mutation. In sickle cell anemia, glutamic acid is converted into a valine acid which is the main cause of sickle cell anemia formation. In this mutation, the shape of oxygen carrying cell i. e. hemoglobin changes into a sickle type. This sickle shape of the cell prevents the flow of blood in the capillaries.
