Question

Fruits stored in a cold chamber exhibit longer storage life because:

  1. exposure to sunlight is prevented
  2. concentration of carbon dioxide in the environment is increased
  3. rate of respiration is decreased
  4. there is an increase in humidity

Answer:

Option C: rate of respiration is decreased
