The nitrogen cycle which is converted to an intermediate, is generally used by the organism at certain levels, hence option c nitrogen gas, ammonium, nitrite, nitrate is correct.
What is the nitrogen cycle?The nitrogen cycle in the biogeochemical cycle converts nitrogen into various chemical intermediates as it cycles into the air, terrestrial, and marine environments.
The nitrogen conversion processes occur through both biological and physical mechanisms. Fixation, ammonification, the first two steps, nitrification, and denitrification are all important processes in the nitrogen cycle.
The bulk of the Earth's atmosphere contains (78%) majorly composed of atmospheric nitrogen, make the primary source of nitrogen.
Therefore, option c begins with nitrogen gas, ammonium, nitrite, and nitrate in the correct order.

A cell membrane is more flexible than a brick wall. Why might many cells benefit from a flexible cell membrane? and A building has different types of openings, such as windows and doors. Do you think a cell also has different types of openings? Give an explanation for your answer. I NEED HELP NOW I HAVE TO SUBMIT
Answer:
plant: This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
animal :This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.
Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell. The bacteria are only a fraction of the size of the nucleus, but their tiny size is typical for bacteria.
A cell membrane's flexibility aids in the selective passage of substances across it. Endocytosis, a mechanism that enables amoeba to take in food particles from the environment, is made possible by the flexibility of the membrane.
What make cell membrane to be flexible?The majority of natural phospholipids' fatty acids include one or more double bonds, which cause the hydrocarbon chains to twist and are challenging to pack together.
The interior of the membrane can displace freely due to the prolonged hydrocarbon chains of the fatty acids, getting the membrane itself negotiable and supple.
Key fatty acids include arachidonic and docosahexaenoic acids. Due to its four double bonds, arachidonic acid's proportion in phospholipid tails can be slightly increased to improve membrane flexibility.
Therefore, cell flexibility is important for cell to function.
