Answer 1

Answer:

c is right answer answer

Answer 2

(A): Digestion of food is a chemical change. Reason (R): No new substance is formed during digestion.

In this A is true, but R is false.

• A chemical change refers to the chemical transition of one chemical compound into another.
• Because enzymes in the stomach and intestines break down huge macromolecules into smaller molecules so that the body may more easily absorb the food, digestion is considered a physical and chemical process.
• Chemical interactions – alter in oxidation states,  bonding, & structure – of materials (food) with other substances ( acids, enzymes,) in our intestinal systems modify the composition of materials (food).
• Digestion is a mix of chemical and mechanical processes (assuming the human digestive tract). The basic purpose is to break down the food's contents into smaller, absorbable molecules before separating them from the "rest."
• To help with this, the food is mechanically chopped into as little bits as possible (chewing), and chemical processes in the mouth are triggered by both high pH and diverse enzymes from the saliva.
• Specialized enzymes, emulators, and the relatively severe pH facilitate the hydrolysis of carbs, peptides, and lipids when the meal reaches the stomach and other regions of the digestive tract.
• As a result, we may conclude that food digestion is an example of chemical transformation.
