Explanation:
Natural Selection refers to the survivability of organisms based on different traits or genes that they have which then get passed on to their offspring. Based on this information we can say that a population of mountain gorillas in which individuals with genes for long hair survive the cold better is the situation in which natural selection is most likely to occur. This is because longer hair in this scenario is a gene that drastically affects the chance of survival for the gorillas and will most likely be passed on to their offspring.

I believe you're looking for "chemical digestion".
Chemical digestions is where food that we ate is digested into simpler and soluble molecules that can be absorbed by our body. Enzymes are used as a catalyst to speed up the reaction.
One example is the digestion of lipids. Enzyme named lipase is used to speed up the digestion of lipids into 3 fatty acid molecules and 1 glycerol. This way, our body can absorb these simple molecules, and use them in order to make our body function.
On the other hand, physical digestion does not include enzymes, such as chewing in our mouth, therefore, don't mix them up!
