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.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
