hi <3
triglycerides are composed of a glycerol molecule and three fatty acid chains. they aren't considered true polymers as there are no chemical bonds between each of the fatty acid chains
hope this helps :)

Answer:
C) It has a long preganglionic fibers
Explanation:
Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:
- somatic (voluntary) nervous system-controls the movements of the skeletal muscles
- autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
- sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions);contains short preganglionic fibers and long postganglionic fibers.
- parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
- enteric nervous system-controls the function of the gastrointestinal tract.
Answer:
The statement true of all proteins, carbohydrates and fats is that human body is able to synthesize them all.
The statement unique to proteins is that proteins are made up of instructions according to DNA.
Explanation:
Carbohydrates, Proteins and fats are macronutrients and required by body in larger amounts. All these macromolecules are made up of building blocks like proteins are from amino acids, carbohydrates from monosaccharides and fats from triglycerides. Human body can also synthesize these macronutrients. Like proteins can be synthesized by central dogma. Glucose can be synthesized by gluconeogenesis from glycogen and fats can be synthesized from acetyl-CoA and NADPH.
The proteins are made up by a process known as central dogma. The first step of central dogma is replication in which a replicated copy of DNA is produced in a cell. The second step is transcription for the production of messenger RNA from DNA. At last mRNA is used for the production of proteins on ribosomes.
