Question

Food articles like milk, vegetables, and bread are kept in a refrigerator. Medicines are labeled 'Store in a cool, dry place'. By keeping at low temperatures, they are prevented from decay or destruction, because:

• A. bacteria are frozen
• B. chemical reactions slow down
• C. vitamins protect protein
• D. micro organisms can not survive

Answer 1

The correct option is B chemical reactions slow down

At low temperatures (commonly around $14℉\text{to}-13℉[-10℃\text{to}–25℃]$), chemical reactions take place very slowly and pathogens have difficulty surviving.
