One or two words in the following statements are false. Correct them and rewrite the statements.
?? During atmospheric fixation of Nitrogen, urea is produced.
?? sea water is a bad conductor of electricity.

Dear Student

Ans 1. During atmospheric fixation of Nitrogen, Ammonia is produced.

Nitrogen fixation: Process of conversion of nitrogen (N₂) into ammonia (NH₃).

There are two methods that change atmospheric nitrogen into usable forms through the process of nitrogen fixation:

1. During lightning and thunder, the high temperature and pressure in the air convert atmospheric nitrogen into oxides of nitrogen that can dissolve in water to produce nitric and nitrous acids. These fall along with rain.

2. Certain forms of bacteria are able to convert atmospheric nitrogen into usable forms such as nitrates and nitrites. Such nitrogen fixing bacteria are commonly found in the roots of legumes (plants of pulses) inside special structures called root nodules.

These usable forms of nitrogen are absorbed by plants to produce many compounds such as amino acids, which in turn form proteins.

Ans 2. Sea water is a good conductor of electricity.

Sea water is a good conductor of electricity because it contains salts (ions) which help in the conduction of electricity.
