The brain is one of the most complex and important organs in the human body. It controls all the functions of the body, allows us to think, feel, and move, and enables us to experience and interact with the world around us.
Structure of the Brain
The brain is divided into several main parts:
Cerebrum: The largest part of the brain, responsible for voluntary actions, intelligence, and sensory processing.
Cerebellum: Located at the back of the brain, responsible for coordination, balance, and muscle control.
Brainstem: Connects the brain to the spinal cord and controls basic functions such as breathing, heart rate, and digestion.
Thalamus: Acts as a relay station for sensory information.
The student demonstrates an understanding of how science explains changes in life forms over time, including genetics, heredity, the process of natural selection and biological evolution by showing the relationship between physical characteristics of Alaskan organisms and the environment in which they live.
