Astudent is investigating the question “which increases a person’s breathing rate more after three minutes, lifting five-pound weights or lifting ten-pound weights? ” she designs an experiment to test the question. which statement most likely describes the dependent variable in her experiment? the breathing rate is the dependent variable because it can be affected by varying weights. she cannot measure the dependent variable until she finishes the experiment. the time of exercising is the dependent variable because it can be measured. the five- and ten-pound weights are the dependent variable because they can affect the breathing rate.

The breating rate is the dependent variable because it can be affected by varying weights.

Explanation:

In an experiment, the dependent variable is the variable that is not manipulated but is influenced by the changes that are done to the independent variable. In other words, it depends on the independent variable.

So in this case, the breathing rate is the dependent variable and the weight differences is the independent variable because the change in weight is what is changed to see if it will affect the breathing rate, which is the dependent variable.

population. population is the number of people or animals in a particular place. an example of population is over eight million people living in new york city.
