Accepted Answer

# Brief Explanations:
1. Analyze each option based on the text about corn kernels and digestion - related knowledge.
   - For question 1, the text likely discusses the role of kernels and cellulose. Option d is correct as kernels protect DNA.
   - For question 2, the text mentions that cellulose is a small part of corn and corn has nutrients. Option d is correct as it aligns with the idea that most of corn is nutritious and usable by the body.
   - For question 3, enzymes speed up digestion and break food into smaller molecules, which is a well - known biological fact. Option c is correct.
   - For question 4, enzymes are proteins that catalyze biochemical reactions, including food breakdown. Option c is correct.
   - For question 5, less processed food generally retains more nutrients. Option b is correct.
