Question 31

Section II Question 31 - 2010 HSC

(a) Contruct a table identifying structures used by insects, fish and mammals to detect vibrations. (b) Draw diagrams illustrating vocal folds for high and low pitched notes. (c) Explain the effect of location in the retina on the stucture of cones. Outline the role of rhodopsin in rods. (d) Explain causes for lack of action potentials in part of a mammal's brain. Outline how this condition could change behaviour. (e) Evaluate how understanding of the ear and eye has led to development of 3D images and surround sound systems.
