If you want to ask how you will get time to study, then I want to say no time is better from now. 

You should first make goals and give a proper time duration to yourself as 8 hr of sleep 8 hr of job and in rest 8 hr upto 4 to 5 hr to study and next to yourself time. 

After that, you should choose limited and productive study material. 

Give your eagle eyes on previous years question. 

And give regularly mock test. 

If you study only for 4 hours by giving your 100 %, it will much better than providing 10/12 hrs of unproductive study. 

Last but not least, give faith in yourself and your goal. You can do it.

Nitrogen fixation is the process of fix the nitrogen in that form which can easily absorb by the plant. The process in which nitrogen present in air converted into various nitrogenous compound such as ammonia, nitrates, nitrites in soil. Bacteria play an essential role in nitrogen fixation. It is vital for the biosynthesis of plants. 

Fullerene is a spherical molecule of carbon atoms. Carbon can make many allotropes (a structurally different form of the same element) due to its valency. But mainly it has eight allotropes, and buckminsterfullerene/buckyball is one of them. This is C60 spherical carbon allotropes where 60 carbon assembled in pentagon and hexagon. Diamond, graphites and buckminsterfullerene are pure carbon allotropes.
