D)increase the symmetry of the cel.

Quizplus · Accepted Answer

Spines are small protrusions from the dendrites that increase the surface area available for synaptic connections with other neurons. This allows for more efficient communication between neurons and plays a crucial role in synaptic plasticity, which is the ability of the brain to change and adapt over time. Therefore, option A is the correct choice. B, C, and D are incorrect because spines do not play a role in increasing the speed of transmission, eliminating waste products, or increasing the symmetry of the cell.
