One of the effects of the hormone secretin is to stimulate the release of bicarbonate ions into the duodenum, which neutralizes the acid that enters the duodenum with food from the stomach. one consequence of neutralizing the ph in the intestine is that: the enzymatically catalyzed hydrolysis of carbohydrate that began in the stomach is halted in the duodenum. enzymes that catalyze the hydrolysis of carbohydrates are denatured. enzymes that catalyze the hydrolysis of carbohydrates are active. carbohydrates are not as easily broken down in this neutral environment.

enzymes that catalyze the hydrolysis of carbohydrates are active.

Explanation:

The pH within the small intestine should be neutral so that enzymes that break down macromolecules can work properly (unlike in stomach where the enzymes require acid pH). Small intestine is part of the digestive system, in which proteins, lipids and carbohydrates are hydrolyzed. Carbohydrate digestion in small intestine is performed by pancreatic enzyme amylase, maltase, sucrase, and lactase (secreted by the small intestine). Neutral environment is suitable environment for those enzymes.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
