<u>Answer:</u>
<em>lightening breaks</em><em> down the nitrogen molecules and provide a suitable environment to mix with oxygen (high temperature and pressure). </em>
<em>When these mix with water, the nitric acids are obtained which dissolves in soil and plants can use those </em><em>nitric acids for growth and development.</em>
<u>Explanation:</u>
The role of bacteria in nitrogen cycle is it breaks down the protein content in <em>dead plants and animals during decay process</em> and ammonia is formed.
Then the<em> nitrifying bacteria causes nitrification</em> which turns nitrogen into soluble nitrates that the plants can absorb.

Explanation:
The body's balance between acidity and alkalinity in the human body is regarded as the acid-base balance which is measured on the basis of the pH and the concentration of carbon dioxide and bicarbonate in the blood. The organs that controls acid-base balance are lungs, kidneys and pancreas. Theses organs control blood pH by releasing carbon dioxide from the lungs because it is a waste product slightly acidic in nature and excreting excess of acids and bases from the body.
