Question

Cephalization is primarily associated with

A. type of digestive system.
B. adaptation to dark environments.
C. fate of the blastopore.
D. bilateral symmetry.
E. method of reproduction.

Answer 1

Cephalization is primarily associated with bilateral symmetry, where a concentration of nervous tissues and sensory organs in the head region allows organisms to interact with their environment. It is an important step in the evolution of a brain.

Step-by-step explanation:

Cephalization is primarily associated with bilateral symmetry. Bilaterally symmetrical organisms have a concentration of nervous tissues and sensory organs in the head region, which is where they first encounter their environment. This concentration of nerve tissue is called cephalization and is an important step in the evolution of a brain.
