Design an experiment to test the effect of aeration on the growth of roots of bean seedlings. in your
answer, be sure to:
• state one hypothesis the experiment would test
• describe how the control group will be treated differently from the experimental group
• identify the dependent variable in the experiment
• state one reason why many setups should be used in both the experimental and control groups
• state one reason why several different kinds of seedlings were not tested in this experiment

One hypothesis can be that there is an effect of aeration on the growth of roots of bean seedlings.

Control group: has "no aeration"
Experimental group: has the aeration treatment

Dependent variable: growth can be measured in the length of the seedlings probably in centimeters

Researching is composed of various explorations in utilizing the scientific method in the process. It also, answers any scientific inquiry with the use of scientific method. Research enables and promotes the scientific community at a larger scale. Contributing and collaborating knowledge all-over the people and persons in science. Researches play a big role in everyone’s academic identity because 
1.       It actively makes the individual scientific in approach to things of curiosity and makes him/her use the knowledge to study and produce results which 
2.       The scientific society will benefit by this particular study and can work together to better explore and discover.    

I think c but i’m not 100% sure
