Final answer:
Weight-bearing activities build better bones by stimulating bone cell production and increasing bone density through small fractures that signal the creation of new bone tissue.
Step-by-step explanation:
Weight-bearing activities build better bones because they put stress on the bones, which stimulates the bone cells to increase their production and density. When we engage in weight-bearing exercises, our bones have to work harder to support our body weight, causing small breaks in the bone tissue. These breaks signal the bone cells to create new bone tissue, making the bones stronger and more resistant to fractures.
