Answer:
See the explanation below.
Explanation:
Chemical digestion in the small intestine relies on the activities of three accessory digestive organs: the liver, pancreas, and gallbladder.
- The digestive role of the liver is to produce bile and export it to the duodenum.
- The gallbladder primarily stores, concentrates, and releases bile.
- The pancreas produces pancreatic juice, which contains digestive enzymes and bicarbonate ions, and delivers it to the duodenum.
The liver, pancreas, and gallbladder are considered accessory digestive organs, but their roles in the digestive system are vital.

Answer:
The exons may be defined as the coding region of the RNA that codes for the particular amino acid. The introns are the non coding region of RNA and must be removed in the final RNA product.
Exon shuffling result in the formation of new gene. The alteration of the exon and intron structure leads to the new gene function in evolution. The genes that are favored and conserved in the evolution perform new gene function. The genes that are selected against are deleted during the evolution.
