What are five problems with this experimental design that could have caused the inconsistent results? the rest that you can not read is: already started growing.

Results: Some of the roots seemed really big. Other roots seemed normal or small.

Conclusion: They couldn’t tell what the effect of the compost was because the results were inconsistent.

Hello. You forgot to show the description of the experiment. The description of the experiment is attached:

The problems were:

Explanation:

An experiment must be carried out with completely equal resources, elements and factors for all tested objects and variables. In this case, for the experiment to have an efficient result, it would be necessary that the same species of plant be used (since the same species would present the same elements of development). In addition, all plants should be exposed to the same environment and receive the same amount of compost at the same stage of vegetative growth. These things did not happen in this experiment and therefore the results were inaccurate.

these have to be in your own words
