Which of the structures below represents a fat? A monomer made up of a nitrogenous base, a five carbon sugar, and a phosphate group bonded together. A molecule made up of four carbon rings with other atoms bonded to those rings. A glycerol molecule with three fatty acid chains attached to it. A polymer made up of multiple glucose molecules bonded together.

The correct answer for this question is: "Amino acids." The monomer that varies based on the structure of their side chains is the amino acid.

The correct answer for this question is: "C.Steroid." The type of molecule that is represented by the model below: A molecule made up of four carbon rings with other atoms bonded to those rings, is Steroid.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
