Question

which of these functions is not related to lipids? lipids can
form a protective cushion around major organs.
dissolve easily in water.
form much of a cell membrane.
insulate against heat.
provide water-repelling coatings.

Explanation:

Lipids are hydrophobic (water-fearing) molecules, so they do not dissolve in water. The other options describe valid biological functions of lipids: adipose tissue (a lipid) cushions organs, phospholipids form cell membranes, lipids like fat insulate the body, and lipids such as waxes create water-repellent coatings.

Answer:

dissolve easily in water.
