Explanation:

Answer 2

Answer:

Different parts of the gastrointestinal tract have different functions to them, acting upon different nutrients and their absorption.

Explanation:

The stomach turns the food acidic with the help of hydrochloric acid, which is then acted upon the pepsin to partially digest the proteins present in it.

It then passes on to the duodenum where it is turned alkaline. Then, the proteins and the carbohydrates are digested by the amylases and proteases.

Then, the nutrients of the rice are absorbed into the bloodstream, while the others are then passed onto the large intestine to be excreted.
