B. Protein
Amino acids are organic compounds that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
Answer: comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary and phylogeny.
Capillaries are the end structures in the artery system that bring oxygenated blood from your lungs to the rest of your body.

reduce lipid mobility
decrease membrane fluidity
When fatty acid tails are saturated, it means that their conformation is perfectly straight becoming easy to compact more and more fatty acids, as they fit perfectly together, and therefore reducing lipid mobility. In turn, if lipid mobility is reduced, the membrane fluidity is decreased because the lipids are too "stiff" together.
