The correct answer is option (h) the breathing rate to supply more oxygen to cells for the release of energy.
Breathing refers to the process of inhaling oxygen and exhaling carbon dioxide from the lungs. A normal breathing rate at rest is around 15 breathes per minute which is significantly increased to 40 -50 breathes per minute during vigorous activity or excercise.
During exercise, the breathing rate, pulse rate and lactic acid levels increase in the human body. Muscle cells have an increased need for energy and heart pumps more oxygen to the muscle cells to meet the requirement. Breathing rate increases to supply more oxygen to the muscle cells which is required for the oxidation of the glucose, release of more energy and to get rid of the carbon dioxide.
The answer is: decreased circulation
Increased flexibility tend to be achieved by implementing stretching exercise. When we stretch, we would improve our blood circulation because the movement help the blood to flow in different type of direction. In the long run, exercises to increase flexibility would have positive benefit for our cardiovascular system.
Molecules that have the same chemical formula but have different molecular structures are: Isomers.
Answer:
Higher objects (with further to fall) have greater potential energy. therefore the maximum height would have the highest amount of potential energy
