Question

refer to the passage. the results of the experiment are most useful for explaining which of these functions of lipids in organisms? a teacher assigns the following experiment to a class. draw an outline of a birds feather, and color one half of the outline with a thick coat of wax from a wax crayon. leave the other half uncolored. next, sprinkle a few drops of water on both halves of the feather. you will observe that the water soaks into the plain paper. the waxy coat, however, allows the paper to remain dry. water forms tiny beads on top of the wax instead of soaking through it. forming a waterproof covering on feathers, leaves, & fruits. providing energy for the cell. allowing water to pass through the cell membrane. replacing water in dry environments.

Explanation:

The experiment shows water - repelling property of wax. Wax is a lipid. In organisms, lipids in the form of waxes can form waterproof coverings on feathers, leaves, and fruits. This is demonstrated by the water beading on the wax - coated part of the feather outline while soaking into the uncoated part.

Answer:

A. forming a waterproof covering on feathers, leaves, & fruits
