Solution

The answers to your questions are:

For the first question, "The change in absorbance is used as the basis for assaying enzymes using __________", the correct answer is d) spectrophotometer. Spectrophotometry is a method used to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution.

For the second question, "In lactose industry, which immobilized enzyme is used?", the correct answer is b) Lactase. Lactase is an enzyme that breaks down lactose, a sugar in milk and milk products. This enzyme is commonly used in the dairy industry, particularly in the production of lactose-free products for lactose-intolerant individuals.
