<h2>Fixation</h2>
Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
<h3>Biologically: </h3>
Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
<h3>Through lightning: </h3>
Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.

This is false. The more similarities the the amino acid sequences have, the closer related are the species. Therefore the more differences in the sequence, the more further related the two species are.
Answer:
The answer is scientific method.
Explanation:
The Scientific Method:
The Scientific Method is the standard process of experimentation and inquiry used to test hypothesis and answer scientific questions.
Every scientific question requires a specific form of the scientific method, with the variations ranging from the scope of the hypothesis to the experimental design and data analysis methods.
The steps of the scientific method are as follows:
1. Observation/Question
2. Hypothesis
3. Experimentation
4. Data analysis
5. Conclusion
The conclusion includes analysing the results and developing further hypotheses and testing them. If the hypothesis remains irrefutable, it becomes a theory. If the theory remains irrefutable after rigorous experimentation in various studies by multiple scientists, the theory becomes a law.
