Dante loves taking care of the chickens on his farm. He feeds them rice everyday. His Grandma told him that he should feed them corn everyday instead of rice because it will make them grow fatter. He decides to do an experiment to test what type of food will make his chickens fatter. Before the experiment, the chickens weigh an average of 5 pounds. David makes two groups of chickens. He feeds Group A rice everyday, and feeds Group B corn everyday. After one month, David weighs the chickens to see if they gained any weight. Group A weighs an average of 5 pounds and group B weighs an average of 7 pounds. What is the test variable (independent variable) in this experiment? *

They were eaten by birds more and more, while the rare dark colored moths blended in better on the darker trees. This made the dark colored moths have a higher survival rate.
