which of the following best describes how the brain grows or develops over the course of the lifespan?

c)axons become coated with myelin sheath.

b)the brain prunes or eliminates unused neural connections.

a)the brain forms new neural connections.

d)all of the above statements accurately describe how the brain grows and changes over time.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: The brain does form new neural connections throughout life, especially during learning and development.
• Option B: Neural pruning (eliminating unused connections) is a key process in brain development, refining neural networks.
• Option C: Myelination (axons being coated with myelin sheath) occurs over time, speeding up neural transmission and is part of brain development.

Since all A, B, and C are accurate descriptions of brain growth/development over the lifespan, option D is correct.

Answer:

D) All of the above statements accurately describe how the brain grows and changes over time.
