The nitrogen cycle is most directly dependent upon-
vovangra [49]

Answer:

B) Nitrogen-fixing bacteria and lightning

Explanation:

Nitrogen cycle is the natural process in which atmospheric nitrogen is converted into nitrite and nitrate with the help of bacteria.

Nitrogen cycle is directly dependent on nitrogen-fixing bacteria and lightning.

As bacteria are responsible for most of the chemical conversion in the nitrogen cycle such as nitrogen fixation (first step) is done by soil bacteria (Cyanobacteria) that form ammonia, which is toxic to plants; nitrification in which ammonia is converted into nitrites and nitrates with the help of Nitrobacter and denitrification bacteria involve Pseudomonas, and Achromobacter which convert nitrite and nitrate into nitrogen.

The lightning breaks nitrogen molecules and allow  it to combine with oxygen in atmosphere which further dissolve in rain and form nitrates.

Hence, the nitrogen cycle is most directly dependent upon nitrogen-fixing bacteria and lightning and the correct option is B.

The bacteria which had mutation became resistant to the antibiotic and survived and keeps on increasing, promoting natural selection.

Explanation:

The bacteria rapidly divide, the chances of mutation in the gene increases manifold.

The strains of bacteria causing tuberculosis and staph infection got mutated at DNA level such that they became resistant to antibiotics when tested those susceptible did not survive. These mutations were not harmful to bacteria and the resultant bacteria survived.

These bacteria which survived and proliferated as the environment was in their favour.

Thus, Darwin's Theory of Natural Selection is acceptable here as it says if a mutation is occurring towards the increase in population, they will be selected ones.
