Answer 1

The correct option is A A- 4, B- 2, C- 3, D- 1

The stomach starts chemical digestion of protein. The enzyme pepsin is responsible for protein breakdown. The large intestine is primarily responsible for removing water from the contents of the intestine and making it ready for removal from the body. The small intestine is the part of the intestines where 90% of the digestion and absorption of food occurs. The main function of the small intestine is absorption of nutrients and minerals from food. Liver is an accessory digestive gland and produces bile, an alkaline compound which aids in digestion via the emulsification of lipids.
