How do cells become cancerous?

accelorated cell division

Explanation:

the cells grow faster, this is why many use chemotheropy it kills all fast growing cells

Cell multiplication

Explanation:

When a cell strats growth and multiplies too much it becomes a cancer. This results in tumor.

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.
