We can count the number of heart beats in a minute of a regular daphnia and try and get a new one with the same specifications as the old one that may have died. It is also a good idea to get a new one as we want to see how much it affects it from ordinary instead of adding the caffeine one after another

These results led to people trying out these trails because the participants knew the shock would be painful but not dangerous. With that being said‚ it shows you the mindset of the people during that time. People were laid back and were
