The nervous system consists of the brain, spinal cord, nerves, and sensory receptors. The sensory receptors detect changes in temperature, pressure, or light, and send messages (via electrical signals called nerve impulses) to the central nervous system (brain and spinal cord) so that it is constantly informed about what is going on. The central nervous system then assesses this information and responds by activating the appropriate body effectors.

What is the difference between active and passive transport?
Active transport requires energy, passive transport doesn't.
Active transport molecules move across a cell membrane and passive transport doesn't.
Active transport involves oxygen and water molecules, passive transport does not.
What does it mean when substances move "down a concentration gradient?" Choose the best answer.
They move from areas where there are few particles to areas where there are lots of particles.
They move from areas with lots of water to areas with little water.
They move from one side of the cell membrane to the other.
They move from areas where there are a lot of particles to areas where there are few particles.
