Susan was examining a cell under the microscope and noticed the formation of a cell plate in the midline of the cell and the formation of nuclei at opposite poles of the cell. The cell under examination was most likely .

plant cell undergoing Cytokinesis

Explanation:

Cytokinesis is the final stage of cell division process, during which the cytoplasm splits into two and the cell divides.

In plant cells, a cell plate forms along the middleline of the cell. Then, a new nuclei form along each side of the cell plate.

The cell under examination was most likely a plant cell undergoing cytokinesis.

Explanation:

Cytokinesis is the final step in cell division, coming right after mitosis (the process in which a eukaryotic cell divides itself into two identical daughter cells). Cytokinesis consists of the split in two of the cytoplasm.

In plant cells, cytokinesis begins when a cell plate forms along the equator, from which new cell membranes will form to wrap the new daughter cells.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
