Waxes, oils and fats are examples of
A
Carbohydrates
B
Lipids
C
Proteins
D
Nucleic Acids
Explanation: 

Detailed explanation-1: -Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein.

Detailed explanation-2: -Fats, oils, and waxes are all examples of lipids. There are lots of lipids, but they all share the trait of being at least partially hydrophobic (meaning they won’t mix with water). Water molecules are polar because they have positive and negative ends, rather like little magnets.

Detailed explanation-3: -Waxes and Oils are lipids, having hydrophobic properties, and are derived from plants and animals. Oil is simply fat with unsaturated fatty acid chains, and is found in liquid form at room temperature.

Detailed explanation-4: -Lipids that are important to our discussion include fats and oils (triglycerides or triacyglycerols), fatty acids, phospholipids, and cholesterol. Fats and oils are esters of glycerol and three fatty acids.

Detailed explanation-5: -Fats are esters of fatty acids with glycerol, and are solid at, room temperature. On the other hand, waxes are esters of fatty acids other than glycerol. They contain one mole of long chain fatty acid esterified with one mole of high molecular weight monohydroxy alcohol.
