Step-by-step explanation:
Digestion may be defined as the process of breakdown of large food particles into smaller substances. The product of digestion must be absorbed in the blood stream.
The digestion process can be seen in laboratory as well. Starch, water, body amylase,temperature, testing after 30 mins result in the process of digestion. The digestion takes time to digest the starch by the enzyme amylase and result of digestion will be seen after 30 minutes rather than testing immediately.
Thus, the correct answer is option (b).
