Atmospheric nitrogen, despite being abundant, is largely unusable by most living organisms due to its non-reactive nature. It can only be used after it's converted into reactive forms like nitrates or ammonia, a process carried out by certain bacteria through nitrogen fixation.
Atmospheric nitrogen is largely inaccessible to most living organisms, including plants and animals, due to its stable, triple-bonded molecular structure. However, it can be used by most living things after it has been converted into more reactive forms such as amino acids, nitrates, or ammonia, a process known as nitrogen fixation.
Nitrogen-fixing bacteria, which live freely in the soil or in symbiotic relationships with certain plants, play a fundamental role in transforming atmospheric nitrogen into a form that other living organisms can use for their growth and survival. This process is a vital part of the nitrogen cycle, a crucial ecological system that regulates the amount of nitrogen in the environment.

of time.
Answer:
The answer is Climate.
Answer:
The answer to this question would be: antiviral agents that block any of the steps in the transcription process, since without newly produced RNA, or DNA for the new virions, it would be impossible for the virus to replicate itself and thus spread out to infect further. An example of such a drug is aciclovir, and what they do is inhibit, or prevent, the transcription process, either of DNA, or RNA depending on the invading virus, so that viral proteins cannot be coded for and the new virions cannot be assembled.
These agents usually are nucleotide analogues that mimick the DNA, or RNA, that the virus will need in order to replicate its genetic material for the new viruses. However, since they are not the correct material, these analogues will inhibit correct replication, or further coding, of the genetic material. This in turn will ensure that either no proteins, or weak proteins, will be produced and the virus will be left weakened for the attack of the immune system.
