Answer:
Nitrogen can be transformed into a utilizable form like NO2 by the fixation process.
Explanation:
The conversion of nitrogen into various chemical forms is described through the Nitrogen cycle. The nitrogen of atmosphere is less usable. However, it can be made usable by various interactions of complex genes that allow nitrogen conversion by different organisms.
One such interactive process is of Fixation. In this method, nitrogen is modified into ammonia by symbiotic microorganism. They have the enzyme called nitrogenase which makes the bond of hydrogen with nitrogen to make ammonia.
Answer:
A. Oxygen atoms in water molecules are also attracted to hydrogen atoms in other water molecules.
Explanation:
Water molecules are forge by hydrogen bonds with one another. Here, the partly negative charge on the Oxygen (O) of one molecule would forge a hydrogen (H) bond with the partly positive charge on the hydrogens of its neighbouring or other molecules. Water molecules can also form a bond with other polar molecules and ions.
In the diagram, H is white and O is gray coloured molecules.
