Abiotic means something dead. Its not that hard.
Explanation:
You test a hypothesis by carrying out an experiment.
<span>Your paper towel rope (or wick) starts getting wet, after a few minutes you will notice that the empty glass is starting to fill with water, it keeps filling until there is an even amount of water in each glass.</span>
The purpose of this is to indicate the changes or effects in pulse rate bought by exercise.
We can also call this the control set up, it is where all the setting is same except without the variable that is going to be tested. So in this case, that variable is exercise.
So it is supposed that both set up has same settings such as the amount of time measuring the pulse, or the position of arm or neck etc.
