Question: Answer the following question given this paragraph: Other lipoproteins also transport lipids throughout the body, but different types of lipoproteins tend to serve different functions. We will discuss some of these differences in the section below on cholesterol and heart disease. Lipoproteins are often classified into five different groups based on their densities. In increasing order of density, these groups include chylomicrons, very-low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). Q: On what basis are lipoproteins classified? Choices: - diameter - mass - weight - density A:
Answer: density
