Cephalization describes the process by which organisms develop a distinct head. The head of a cephalized organism contains a concentrated group of nerves, or brain, that controls the rest of the organism, as well as specialized organs for consumption and perception, like mouths, eyes and ears. Cephalized organisms exhibit a distinct division between parts of the body; they have a front, back, top and bottom. These animals comprise the bulk of animals that are encountered on a daily basis.

Answer:
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
The evolution of similar forms in different lineages when exposed to the same selective pressures is<u> convergent evolution. </u>
<u></u>
Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.
<h3>
What is convergent evolution?</h3>
Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.
Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.
Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.
The evolution of similar forms in different lineages when exposed to the same selective pressures is <u>convergent evolution. </u>

Amoebas are single-celled organisms, which means that they are composed of just one cell. Each amoeba is a cell capable of performing all living functions by itself. They can reproduce asexually. They are protozoans with no fixed shape. Most have no hard parts and look like blobs of jelly.
