Explanation:

Question 1 (True/False)

The meninges are the protective coverings of the brain and spinal cord, and they consist of the dura mater (outermost), arachnoid mater, and pia mater (innermost). So the statement is correct.

Photoreceptors (like rods and cones in the eye) are specialized to detect light energy. Photosynthesis is a process in plants, blood chemistry is detected by chemoreceptors, and heat is detected by thermoreceptors. So photoreceptors respond to light energy.

The spinal meninges from superficial to deep are dura mater, arachnoid mater, and pia mater. So the most superficial is the dura mater.

Answer:

True
