Other than bacteria, which factor leads to nitrogen fixation?
a. lightning b. flood c. rain

Thank you for posting your question. I hope you found what you were after. Please feel free to ask me more.

A. Lightening

The energy produced by the natural lightening process breaks down the nitrogen molecules present in the air into atoms that combines with the oxygen present in the air results in the formation of nitrogen oxides. These nitrogen oxides combines with the rain water forming the nitrates. These nitrates gets deposited and absorbed by the soil. These nitrates makes the soil fertile.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
