They provide insulation and protection for organs.
B
They serve as a primary source of genetic information.

D

Verified step by step guidance1
Step 1: Begin by understanding the role of lipids in the body. Lipids are a diverse group of molecules that include fats, oils, and phospholipids, and they serve several critical functions in biological systems.
Step 2: Review the functions of lipids listed in the question. Lipids provide insulation and protection for organs, function as long-term energy storage molecules, and are important components of cell membranes. These are all well-established roles of lipids in the body.
Step 3: Consider the statement 'They serve as a primary source of genetic information.' Recall that genetic information is stored in nucleic acids, such as DNA and RNA, not lipids. This statement does not align with the biological function of lipids.
Step 4: Compare the incorrect statement ('They serve as a primary source of genetic information') with the other options. The other options accurately describe lipid functions, while this statement is unrelated to lipid biology.
Step 5: Conclude that the correct answer is the statement that does not describe a function of lipids: 'They serve as a primary source of genetic information.'
