Which of the following combinations is most likely to result in digestion?
a. amylase, starch, water, body temperature, testing immediately
b. amylase, starch, water, body temperature, testing after 30 mins
explain.

Option (b).

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).

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
