What is the purpose of the control group in the experiment?  

• to change the detergent concentration  

• To compare the results with a standard where no detergent is used  

• to test different seed types  

• To increase the number of variables tested 

How are the dependent variables measured in this experiment?  

• By measuring the amount of water used  

• By counting the number of seeds germinated and measuring root length  

• By observing the detergent color change  

• By checking the temperature of the dishes

What does the term “biodegradable” mean in the context of this experiment?  

• It prevents water from affecting the seeds.  

• It can be broken down by bacteria in water.  

• It stops the growth of algae.  

• contains phosphates.

What would happen if a farmer irrigated crops with water containing 1% detergent?  

 

• The crops would grow faster.  

• The crop yield might be reduced.  

• The crops would not be affected.  

• The detergent would help the plants absorb more nutrients.

In the experiment, what was the hypothesis?  

   a

• The seeds will germinate only in full light.
