Triglycerides are formed by combining glycerol and three fatty acids. Specifically, the hydroxil groups of the glycerol join the carboxyl group of the fatty acid to form ester bonds.
Phospholipids are made up of two fatty acids namely: long chains of hydrogen and carbon molecules and they are attached to the glycerol "head".
Based on their individual structure, the difference between the two is the number of fatty acids they both contain. Triglycerides has three fatty acids while phospholipids only have two.
The answers are satellites, weather balloons, and automated weather stations these are all correct because I just finished the test and checked.
