Describe the process of signal transduction in cells.

• It involves the direct transfer of DNA between cells.

• It involves the conversion of a signal from one form to another within a cell.

• It involves the breakdown of glucose for energy.

• It involves the replication of RNA.

Which of the following is a component of the central nervous system?

• Heart

• Brain

• Liver

• Kidney

Identify the type of neuron that carries signals from the central nervous system to muscles.

• Sensory neuron

• Motor neuron

• Interneuron

• Glial cell

How do cognitive processes in organisms influence behavior?

• By altering genetic codes

• By processing information and making decisions

• By changing physical appearance

• By producing more red blood cells

What is the function of the myelin sheath in neurons?

• To slow down signal transmission

• To insulate axons and speed up signal transmission

• To produce neurotransmitters

• To connect neurons to blood vessels

Explain the role of neurotransmitters in the nervous system.

• They provide structural support to neurons.

• They transmit signals across synapses between neurons.

• They store energy for neurons.

• They protect neurons from pathogens.
