Which one doesn't belong: a deep ocean trench, an island arc of volcanic islands, or a mid-ocean ridge? explain your answer.

Mid-oceanic ridge

Explanation:

In a convergent plate boundary, the denser plate sinks below a less denser plate. Due to this, a subduction zone is formed, marked by a deep sea oceanic trench. This trenches are long and narrow depression that separates two plates. The subducting plate undergoes partial melting at greater depths, as a result of which the magma is forced to rise up due to the interior heat supply, resulting in the formation of volcano, volcanic or island arc.

Whereas, mid oceanic ridges occurs in the divergent plate boundary, due to which sea floor spreading takes place, marked by the presence of mid-oceanic ridge where the new materials are added to the crust.

Thus, according to the given options, the oceanic trench and volcanic island arc are the two features that forms in a convergent plate boundary.

Hence, the mid-oceanic ridge is not a feature of convergent plate boundary.

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.

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b
