If a neuron were a tree, the trunk would represent the and the small branch extensions would represent the
a. dendrites; axon
b. axon; dendrites
c. dendrites; cell body

B. axon; dendrites

The axon is a long, slender projection of a nerve cell that typically conducts electrical impulses away from the neuron's cell body.

The dendrites are short branched extensions of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body.

b is the best answer for this question.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
