Answer:
the rats weight loss
Explanation:
The dependent variable would the weight of the rats.
The dependent variable is the variable whose value is dependent on another variable during an experiment. It is the actual variable set out to be measured or tested by researchers. The effect of the manipulation of the independent variable is measured on the dependent variable.
Hence, in an experiment aimed at determining whether a new diet medication will help rats to lose weight, the weight loss by the rats would be the dependent variable.
