The food molecules that are absorbed from the small intestine lumen into the lacteal, the lymphatic capillary located within the villus would be the lipids. Most of the dietary lipids are neutral fat or the so-called triglyceride. These are composed of a glycerol backbone wherein each carbon is linked to a fatty acid. In the small intestine, the villi, microvilli and plicae circulares functions to increase the surface ares that is available for the absorption of the nutrients. Each of the villus consists of a network of capillaries and lymphatic vessels which are called the lacteals which is responsible for the absorption of lipids.
Explanation: There are many birds with colors that are variously different on the Galapagos.
So, Darwin carefully observed the finches of the Galapagos island. What he noticed was that they were similar to the mainland finches, but each island finch has different colored feathers.
In intravenous ossification, bone develops directly from sheets of mesenchymal connective tissue. In endochondral ossification, bone develops by replacing hyaline cartilage. Activity in the epiphyseal plate enables bones to grow in length. Modeling allows bones to grow in diameter.
