Answer:
Faster or slower diffusion depending upon the concentration
Explanation:
Given: When you added different concentrations of [tex]KMnO_4[/tex] to wells in a Petri plate, they had different larger or smaller rings of diffusion
Solution:
If we add more concentration of [tex]KMnO_4[/tex], there will be more gradient which results in faster diffusion.
If we add less concentration of [tex]KMnO_4[/tex], there will be less gradient which results in slower diffusion.
