in which sympathetic pathway does the preganglionic neuron synapse with a ganglionic neuron, and the postganglionic axon does not leave the trunk via a gray ramus, but instead projects directly to the effector?

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.

cell division is not regulated in tumor cells.

the cost of mining is extremely low compared to the money earned from mining, creating income to improve the environment.
