Question

what one characteristic do all lipids have in common?
all lipids are insoluble in water
all lipids provide quick energy storage.
all lipids pass on genetic information.
all lipids dissolve easily in water

Explanation:

Lipids are non - polar molecules. Water is a polar molecule. Due to the principle of "like dissolves like", non - polar lipids are insoluble in polar water. Lipids are not for quick energy storage (carbohydrates are for quick energy), and they do not pass on genetic information (nucleic acids do that).

Answer:

All lipids are insoluble in water
