Answer:
There are no options to this question, however, it can be answered. The answers to the blank spaces are:
1. Fatty Acids
2. A decrease in the rate of lipid breakdown
Explanation:
Lipids are large biomolecules that are formed from monomeric units called FATTY ACIDS. Digestive enzymes such as lipase as described in this question breaks down lipids into its monomer called FATTY ACIDS. 
However, enzymes are proteinous molecules, meaning they are subject to denaturation when exposed to adverse conditions such as heat. According to this question, the scientist heats the enzymes and finds that it can't bind onto the lipids anymore because it has been DENATURED. This situation will result in the DECREASE IN THE RATE OF LIPID BREAKDOWN because the enzyme in charge is no longer functional.

Answer:
A
Explanation:
Without organizing you can go on with the next steps since data alone is worthless but information (organized data) is the most important thing for a scientific investigation.
