independent
growth hormone administration

Explanation:

Identify the experimental setup

Using the Experimental Variables knowledge point, we analyze the scenario:

• Independent Variable: The factor manipulated by the researcher, which is the administration of growth hormone.
• Dependent Variable: The factor being measured to see the effect of the independent variable.

Determine the measured outcome

The scenario states: "Both cows were weighed at 2 years."
Therefore, the measured outcome (dependent variable) is the weight of the cows.
