Question

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

Answer 1

Answer: i'm way late, in simpler terms the answers are 2 and 4

Step-by-step explanation:

got it correct.

Answer 2

Hypothesis can be: There is a significant difference between plants' height with aeration and with no aeration.

Independent Variable: Aeration and no aeration
Dependent varibale: growth of the plant measure through its height

Many setups should be done to avoid inconsistencies and validate between results in the two treatment conditions.
