Question

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 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. the results of the experiment most strongly support which conclusion about the polarity of lipid molecules? a. lipid molecules are polar because they mix poorly with liquids, such as water.

Explanation:

Polar molecules interact with water (hydrophilic), while non - polar molecules do not (hydrophobic). Wax, which contains lipids, repels water. This shows that lipid molecules are non - polar as they do not mix with water. Option A is incorrect as it claims lipids are polar when the experiment shows the opposite.

Answer:

There is no correct option shown in the provided text as the correct conclusion is that lipid molecules are non - polar because they repel water, but no such option is given.
