<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.

<span>A liquid that can easily pass through cell membranes is water. That is what is used in determining the concentration of the solute inside a living cell. You can place the cells in different osmotic environments. Then you observe and determine the environment that causes no uptake of water.</span>

<span>This process enables the final strand to actually bind itself to the complementary, or matching, pieces of the regional mRNA strands. RNA can be degraded in many different ways that follow many different forms. In this particular case, the degredation of the single-stranded RNA created the new ability for binding.</span>
Answer:
B
Explanation:
Glycogen is the process of storing excess glucose. During fight or flight, catabolism is the fore action of the body. Production of glucose for release of energy not conservation of energy.
