Question

In an experiment, Dr. Travis examined the effects of calcium intake on osteoporosis, a condition that causes an increased risk of bone fractures. In the experimental design, the amount of calcium is variable. The risk of bone fractures is

Answer 1

Osteoporosis refers to a disorder featured by diminished bone mass and loss of bone tissue, which may result in fragile and weak bones.  

Osteoporosis can be caused by having an excess amount of calcium year after year. Thus, in order to inhibit the consumption of additional calcium, the body constitutes as less vitamin D as probable. Hyperthyroidism greatly enhances both the consumption of calcium into the bones and expulsion from the bones, ultimately resulting in osteoporosis.  

In an experiment, Dr. Travis examined the effects of calcium intake on osteoporosis, a condition that causes an increased risk of bone fractures. The amount of calcium is the independent variable. The risk of bone fractures is the dependent variable .

Answer 2

Answer:

The risk of bone fractures is the dependent variable.

Explanation:

A dependent variable is a variable that needs something to happen, in other words, this variable depends on a condition, this condition is the independent variable. In the case of the experiment set out in the question, Dr. Travis examined the effects of calcium intake on osteoporosis, a condition that causes an increased risk of bone fracture, in which case the risk of bone fracture depends on the existence of calcium intake. For this reason, we can conclude that the risk of increased bone fracture is a dependent variable, because it needs the occurrence of calcium intake, which is the independent variable.
