Step 1

Since there are multiple questions, we are authorized to answer only the first one, that is,11.2. If you require the answers of the other questions, please post the questions separately again.

Step 2

Lipids are one of the four major groups of organic molecules; the other three being proteins, nucleic acids (DNA), and carbohydrates (sugars). Lipids are made up of the same elements as carbohydrates: carbon, hydrogen, and oxygen. However, lipids tend to contain many more hydrogen atoms than oxygen atoms.

Lipids include fats, steroids, phospholipids, and waxes. Lipids play an important role in living organisms. Some of their main functions include energy storage, hormones, and cell membranes.

One main characteristic of lipids is that they are non-polar molecules, which means that they do not dissolve in water.
