Answer 34

focuses vision when contracted/divids eye in two chambers

Question 35

photoreceptor cells rods: cones:

Answer 35

more sensitive to light (night vision) less sensitive to light (visual activity and color)

Question 36

optic disc

Answer 36

no rods or cones, blind spot, form optic nerve

outer ear | pinna -> tempanic membrane

Answer 37

pinna (auricle) | auditory canal

Question 38
