Step-by-step explanation:

Answer 2

The risk of bone fracture is the dependent variable.

Explanation

A dependent variable is the variable in the test experiment which is being measured by the scientist. The independent variable is that one which changes or is being controlled in the scientific experiment.The effect/amount of calcium intake on osteoporosis is a condition controlled by the scientist Dr. Travis thus it is the independent variable. How the risk of bone fracture occurs (maybe increase or decrease) would be the dependent variable.
