The Human Body Is Made Up of Specialized Cells That

Multiple Choice

The human body is made up of specialized cells that perform different functions. For example, a neuron is a specialized cell of the nervous system that receives and transmits signals throughout the body. To perform these tasks, the neuron uniquely possesses branched protoplasmic protrusions, called dendrites and axons, which conduct the signals to and from its cell body. This illustrates which of the five major biological themes?

A) interaction among biological systems
B) evolution
C) interrelation of structure and function in biological systems
D) activity of living cells
