The purpose of bothe mitosis and meiosis is to create new cells. Both processes involve replication of genetic material within the cell, and both take place within a sexually reproducing individual. There is difference between the process, however. One is crucial difference? 1.) meiosis creates exact replica of parent cell, while mitosis shows genetic diversity
2.) Mitosis creates an exact replica of the parent cell, while meiosis shows genetic diversity.
3.) only meiosis allows for the possibility of gene point mutations
4.) Only mitosis allows for the possibility of translocation

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.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

it depends on how much it could carry.
