Q: Which equation best represents the relationship between bone mass and bone remodeling rate, given that 7% of bone mass is recycled each week?

$$M_{recycled} = M_{total} \times 0.07$$

Q: Which equation best describes the volume of bone replaced after 10 years if the rate of compact bone replacement is constant and the initial volume is $$V_0$$?

$$V_{replaced} = V_0$ \times 1$$
