What is the similarity between digestion of food and formation of curd from milk?
Answer and explanation
Correct answer: New substances are formed in both
Digestion and curd formation are both chemical changes because the original substances are converted into substances with different compositions and properties. Digestive enzymes break complex food molecules into simpler molecules. During curd formation, bacterial activity converts lactose and changes milk proteins, producing curd with new characteristics. Neither process is merely a change of state or shape, so options B, C and D do not describe the similarity.
