Respuesta :
Activate,cells can be classified by their activity.For example fat cells are one of the least active cells and it's hard to activate them;that's why it's hard to lose weight.The least active cells are bone (aka bone marrow cells) that are never active unless there's a fracture.Cells can also be classified by the amount of water they carry and their age.So when you're doing a lot of physical activity your heart rate and breathing increases because your cells are more active.
Answer:
Remove the metabolic waste quickly
Explanation:
The increased breathing rate ensures intake of oxygen into the body while the increased heart rate leads to increased oxygen supply to the muscles. The oxygen serves to remove the metabolic waste (for example: carbon dioxide) produced during muscle contraction and thereby, enables the cells of the body to perform more efficiently.
