Answer:
ligament of Treitz
Explanation:
On the basis of anatomy and functions, the small intestine is divided into duodenum, jejunum, and ileum. Duodenum is the first part of the small intestine that starts at the pyrolic sphincter and ends at the suspensory ligament of Treitz. Beyond the suspensory ligament of Treitz, jejunum, and ileum are present without any anatomical distinction to delineate them from each other. Also known as suspensory ligament of the duodenum, the ligament of Treitz is a thin band of muscle and holds duodenum and jejunum in place.

Answer:
<em>No, these exceptions do not discredit natural selection.</em>
Explanation:
Natural selection tends to favour those organisms which are better adapted to live in an environment. But it does not completely remove the other organisms from the world that are less adapted to live in an environment. Usually, the number of these organisms that are not favoured by natural selection is very less as compared to the number of organisms which are favoured by natural selection. As we see, the number of albino animals is far lesser as compared to their wild-type animals.
