Which is an evolutionary trend in the development of nervous systems for bilaterally symmetrical animals?

A) Loss of cephalization
B) Decreased number of interneurons
C) Greater resting membrane potential
D) Increased presence of ganglia

Bilaterally Symmetrical

Describes organisms with body structures that are mirror images on either side of a central axis, common in many animals, including humans.

Evolutionary Trend

A pattern or direction of evolution where a species undergoes gradual changes over time, often resulting in increased complexity or specialization.

Nervous Systems

Complex networks of nerves and cells that transmit signals between different parts of an organism's body to coordinate behavior.
