An organic chemist is studying a sample of a macromolecule. the compound has carbon, hydrogen, and oxygen in its structure. the physical properties of the compound show it behaving in a hydrophobic fashion. when placed in a calorimeter, it appears to have a high energy storage capacity. which of the four types of biological macromolecules was the scientist most likely studying?

The answer is triglyceride. Triglycerides compose animal adipose fats. They produce the highest energy during metabolism than glucose and proteins.Triglycerides are composed of glycerol and three fatty acid molecules. Each fatty acid contains a carboxyl group while the glycerol contains three hydroxyls groups.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
