Where do animals live without a brain? What are they called?​

Відповідь:

Animals that live without a brain are called single-celled organisms, such as bacteria, amoebas, and some types of algae. These organisms are capable of carrying out basic functions like movement, feeding, and reproduction without the need for a central nervous system or a brain. They have simple structures, often consisting of just a single cell, and are capable of performing basic functions through the use of specialized organelles, such as a pulsing membrane or a flagellum, that help them move and respond to their environment.
