Answer 1

A. All lipids are insoluble in water.

Step-by-step explanation:

Macro molecules are also called polymers, which are formed as a result of polymerization of molecules such as carbon, hydrogen and oxygen.

There are four types of macro molecules in the mammalian system which are

• lipids
• nucleic acid
• protein
• carbohydrates

Lipids are macro molecules that do not dissolve in water i.e. they are hydrophobic. they help in the formation of cell membranes and hormones in the body.
