Step 1
Which row in the table gives the function of structure X and structure Y?
Answer
To identify the functions of structure X and structure Y in the diagram, we need to analyze the roles of the corresponding parts of the eye.
Function of Structure X: Structure X is typically associated with the lens of the eye, which is responsible for refraction, i.e., bending light to focus it on the retina. Therefore, it is accurate to state that structure X 'refracts light.'
Function of Structure Y: Structure Y is likely related to the retina, which detects light and converts it into neural signals for the brain. Hence, structure Y 'detects light.'
Based on this understanding, the correct option that matches these functions from the table is shown below:
- Structure X: refracts light
- Structure Y: detects light
Thus, the answer would be option A: 'refracts light' for structure X and 'detects light' for structure Y.
