Explanation: 

Detailed explanation-1: -Beeswax is a waxy substance that is produced by bees and then harvested by humans for a variety of uses. Ancient Romans used beeswax as a waterproofing agent because it is not water-permeable. Beeswax is which of the following types of organic molecule? 1-carbohydrate.

Detailed explanation-2: -Chemically, beeswax consists mainly of esters of fatty acids and various long-chain alcohols.

Detailed explanation-3: -Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of lipids called fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic birds and mammals dry because of their water-repelling nature.

Detailed explanation-4: -Fats in the body serve mainly as an energy storage system. They are also used as insulation to conserve body heat and protect internal organs, to form the main structural material in cell membranes, and to manufacture steroids and hormones to help regulate the growth and maintenance of tissue.

Detailed explanation-5: -The waxy covering on plant leaves, young stems, and fruit is called the “cuticle". It is composed of cutin, a wax-like material produced by the plant that is chemically a hydroxy fatty acid. The purpose of this covering is to help the plant retain water.
