Place the phases of the entire cell cycle in order. #1. chromosomes move away to opposite sides of the cell
12. cell grows
1 3. chromosomes line up across the middle of the cell
14. cell prepares for mitosis
5. cytoplasm is completely divided and new cells are formed
1 6. chromosomes become visible
17. DNA is replicated
18. two nuclei are formed

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
