An investigation was carried out using the two setups shown below. Other than the difference shown in the diagram, all other conditions were identical.  The tubing connected to both flask setups used in the experiment provides oxygen to the solution.


                      Flask 1                              Flask 2

Flask 1 solution contains all essential minerals.

 

 Flask 2 solution contains all essential minerals except potassium.

 

 

1. State the question being investigated. 

 

2. State one possible hypothesis that could be tested using these setups.  

3. What data should be collected in order to test the hypothesis stated in question 2? 

Bonus: Describe one change that could be made in the investigation to improve it.
