Chained Up

In my AP Biology class, we did a lab about trapping a mouse inside of a respirometer to measure its rate of cellular respiration. I felt so bad for the mouse since it was just a little baby and it would be suffering in the tube because we would put the tube under the water to see how much oxygen it would use up. The mouse inside of the tube could be compared to people who are chained up in a cage, unable to speak out their opinions. These people could be the black slaves back in the day when colored people were treated differently, or just people who were falsely accused of crimes and were punished for something they didn’t do. These people would have to bury their opinions and thoughts inside because they are looked down upon, not being able to express the truth in order to break out of their binds.
