Textbook Problem

Which of the following statements is not correct?

  1. (a) Phosphates enhance the growth of algae in surface water.
  2. (b) Melting of the polar ice cap will result in a rise in sea levels.
  3. (c) Heavy metal toxicity can result from the presence of metal compounds of lead, cadmium, and mercury in water supplies.
  4. (d) Reverse osmosis is a good way to effect desalination.

Interpretation Introduction

Interpretation:

The incorrect statement has to be identified from the given options.

Concept introduction:

Growth rate of algae mainly depend on the presence of sunlight and oxygen

Desalination of water is one of the most important steps in the treatment of water and it is carried pout applying the phenomena reverse osmosis.

Melting of the polar ice cap will results in a rise in sea level.

Explanation

Reason for the correct answer:

Growth of algae does not enhance by phosphates (option a) is the incorrect statement.

The growth rate of algae is affected by the presence of sunlight and oxygen. If there is any chemical in great extent then it will negatively affect the growth of algae.

Therefore the option a is the incorrect statement from...
