Which is not a difference between chemical reactions and nuclear reactions? (1 point The subatomic particles involved in the reaction is different.
The amount of energy absorbed during the reaction is different.
The masses of the reactants and products differ.
The amount of energy released during the reaction is different.

helicase, i think thats it

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.

sodium i think the chemical element of atomic number 11, a soft silver-white reactive metal of the alkali metal group.
