(1) = 1 answer/part
Module 18
[the] pupil
The adjustable opening in the center of the eye through which light enters is defined as what part of the eye?
Module 18
[the] pupil

Module 18
[the] iris
True or false:

(1) = 1 anwer/part
Module 18
[your] retina
What defines the following?:
The light-sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information
Module 18
[the] retina
What does the retina contain? (3)
(3) = 3 answers/parts
Module 18
- receptor rods
- receptor cones
- layers of neurons

Module 18
accommodation
