Questions: When you're driving in the city, a traffic light turns from green to red. As your textbook discusses transduction: - the red light is a physical stimulus. - your sensory receptors translate the light into signals for the brain. - the light waves are detected by your eyes. - your brain constructs a representation of the stop light, which means "stop."

The answer is the second one: your sensory receptors translate the light into signals for the brain.

Explanation for each option:

1. The red light is a physical stimulus.

   • This statement is true, but it does not directly address the concept of transduction. Transduction refers to the process of converting physical stimuli into neural signals.

2. Your sensory receptors translate the light into signals for the brain.

   • This is the correct answer. Transduction is the process by which sensory receptors convert physical stimuli (in this case, light) into neural signals that can be interpreted by the brain.

3. The light waves are detected by your eyes.

   • While this is true, it describes the detection of the stimulus rather than the process of transduction itself.

4. Your brain constructs a representation of the stop light, which means "stop."

   • This describes the interpretation and cognitive processing of the signal, not the transduction process.

Summary: Transduction involves the conversion of physical stimuli into neural signals by sensory receptors. In the context of the question, the correct answer is that your sensory receptors translate the light into signals for the brain.
