question 15
1 pts
this layer of the eye is a membrane containing rods and cones, which can become detached:
○ retina
○ aqueous humor
○ sclera
○ vitreous humor
question 16
this layer of the eye is white and fibrous, as seen on the external surface of the eye:
○ cornea
○ iris

Explanation:

Question 15

The retina is the eye's membrane with rods and cones (photoreceptors) and can detach. Aqueous humor is fluid, sclera is the outer tough layer (not with rods/cones), vitreous humor is gel - like. So the correct option is the one with retina.

Answer:

A. retina

Question 16 (assuming the options might be incomplete but from eye anatomy, the sclera is white and fibrous on the external eye. But from given options here, maybe there was a typo, but if we consider the description: the sclera is white and fibrous. But among the given options (cornea, iris), maybe the original options had sclera. But with given options, if we assume a correction, but based on the description, the white fibrous outer layer is sclera. But with given options here (cornea is clear, iris is colored), maybe the options were misprinted. However, if we go by the description, the correct structure is sclera, but if we have to choose from given (cornea, iris), there's an error. But likely a typo, and the intended correct answer related to the description is sclera, but with given options, maybe the question had a mistake. But following the description, the white fibrous layer is sclera.
