Ahuman rbc is approximately 8 µm in diameter. an unknown bacterium measures 1 ocular space using the oil immersion objective compared to 2 minor spaces on the stage micrometer. a. how big is the unknown bacterium (report in micrometers) and b. how does its size compare to the rbc (how many times bigger is one versus the other)?

explanation:

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
