Explanation:

Question 1

The dependent variable is what is being measured and depends on the independent variable. Here, the weight of the cows is measured and depends on whether they got the growth hormone. So the dependent variable is the weight of the cows.

The independent variable is what is manipulated or changed. Here, the growth hormone (giving or not giving it) is the variable being manipulated. So the independent variable is the growth hormone.

Constants are factors kept the same. The amount of food and water, and time of feeding are kept same for both cows. Other options have factors not relevant or not kept constant.

Answer:

a) the weight of the cows
