ok i edited the question

Answer 4

They heartbeats are different because the amounts of physical activity performed at each situation are different. Since a heart is a pump, the frequency of beats quantify rate of circulation of blood through the body. The heart will beat faster when blood needs to circulate faster because it carries oxygen and nutrients that \(O_2\)-depleted tissues need to carry out aerobic respiration.
