Lipids
yes they can
Marine arctic animals use their fat stores for buoyancy and insulation. The fat is made into a specialized form called blubber.
Glycogen (made up the macromolecule carbohydrates)
It's something like, uhh, origanates.
warm blooded animals
it gives them macromolecules such as carbs, amino acids
Feathers help with pushing air aside (for flying) and in most cases they are also used for insulation.
Polymer
enzymatic hydrolysis
Rock wool is used for lost insulation It could also be used for sound insulation
Insulation (electrical) materials are used in electrotechnics and electronics.
The enzymes that are in the stomach are what causes polymeric macromolecules to break down into smaller pieces so that the body can use them. These are found within the digestive tract of humans and other animals.
