A cross section of tissue layers from a whale is shown above. The thick layer of blubber insulates the whale against the extremely cold waters the whale inhabits. What class of biomolecule makes up this blubber layer?

The blubber is an adipose tissue that insulates the animals body, keeping its interior warm and avoiding heat loss. The biomolecules that make up this blubber layer are LIPIDS.

That is the function of blubber in cetaceans?

Bubbler is a thick layer of fatty tissue covering cetaceans' bodies. Its main function is to insulate the animals from the environmental conditions in which they live.

Deep diver individuals are exposed to extremely low temperatures. To survive in these conditions, cetaceans have developed different strategies. One of them is having the bubbler.

This adipose tissue keeps the animal's interior warm enough to accomplish its physiological functions. Besides, it lets the outermost skin layer be as cold as the environment to avoid losing heat.

The composition of the blubber might vary among cetaceans. All of them are composed of lipids, but their lipidic nature might vary. Some of them exhibit more triacylglycerols, while others wax esters.

Besides, fatty acids are stratified through the tissue.

The biomolecule that makes up this blubber layer is LIPID.
