Question

question 3 of 10
the human brain is a complicated system built on ____ units.

a. independent
b. complex
c. simple
d. electrical

Explanation:

To solve this, we analyze each option:

• Option A: "Independent" units would imply the brain's units don't interact, but the brain is a coordinated system, so A is incorrect.
• Option B: "Complex" units would make the brain even more complicated, but the brain is built from simpler components (like neurons) that work together to form complexity, so B is incorrect.
• Option C: The human brain is a complex system that is built from simple units (like neurons, which have basic functions that combine to create complex behavior). This makes sense as complex systems often emerge from simple components.
• Option D: While the brain has electrical activity, it's not "built on electrical units" in the sense of the structure; the basic units (neurons) have electrical properties but are not defined as "electrical units" in this context. So D is incorrect.

Answer:

C. simple
