  • C Changing of the body colour of chameleon to match the colour of the foliage on which it is resting
  • D The release of phosphorus into the phloem of a plant growing in a phosphorus-deficient soil
Correct Answer: Option D
Explanation:

When the plant keeps supplying phosphorus to the phloem even in the case of a deficiency in the soil, it maintains a steady balance on its inside irrespective of the lack in the soil.
