Answer: One consequence of neutralizing the pH in the intestine is that ENZYMES THAT CATALYZE THE HYDROLYSIS OF CARBOHYDRATES ARE ACTIVE.
Explanation: During digestion, partially digested food particles are transported from the stomach to the first part of the small intestines, that is, the duodenum. The food particles that are coming from the stomach are acidic due to the secretion of hydrochloric acid in the stomach. This acidity has to be removed when the food particles get into the duodenum, this is because the enzymes that are needed to break down carbohydrates in the duodenum can not work in acidic medium. Thus, in order for the pancreatic amlayse enzyme to become active and to complete the break down of carbohydrate in the duodenum, the secretin hormone has to stimulate the release of bicarbonate that will neutralize the acidic partially digested food particles from the stomach.
Multicellular organisms require a lot of energy and resources to survive.
Unicellular organisms, on the other hand, require just the basic necessities. On top of that, unicellular organisms don't require a long time to reproduce as multicellular organisms do.
Thus, multicellular organisms are at a disadvantage because they require more energy, sources, and essentially time.
Hope this helps!
