Answer:
3a. As we know and also mention in the question that lipase is an enzyme that digested and break down the fats into fatty acid and it is also known that the action of an enzyme is as follows:
Enzyme + substrate <===> Enzyme-Substrate <====> Enzyme + Product
and here, E+S <----> ES<---->E+P
So, E is Lipase as the enzyme, S is fats, and P is fatty acids
3b. The control group is in this experiment or research is the group in which activity of the lipase is tested with the help of the chemical Orlistat, present in the diet pill as the control group is used to compare the or test the results of the independent variable's response.
3c. The scientist's prediction would be that in the control group fats will not be digested by the lipase into fatty acids and will not lead to any side effects.
