40. ELECTRO- MAGNETIC RADIATION MECHANICAL CHEMICAL (X-rays…) Ultra-violet visible light infra-red (radio waves..) airwaves Ultra-sound hearing range very-low freqs From outside From inside In mouth From same species From outside From inside some insects human vision pit viper bats, dophins, rats human hearing whales, frogs touch, pain Lateral line of fishes vestibular organ proprioception pheromones, smell smell taste pressure In air

42. Bee’s view of a flower – markings visible only because different parts of the petal reflect ultra-violet rays differently.

45. Physical World Sense Organs BrainPerception

46. Eye movements Point eyes to right place Accommodation focus Pupils Light Adaptation Adjust for the light level Transduction Convert light energy to activity in cells

47. Focusing and accommodation

51. AIR LIVING WATER LIVING

52. 1 put on a mask that keeps air in front of cornea 2 rely on a STRONG lens that can change from air-living to water living eg: otter 3 Have a FLAT cornea (to remove its influence) and then use a WATER-LIVING style lens eg. Penguin, flying fish 4 Have two pairs of eyes - one for each environment eg. Four-eyed fish 5 Use a WATER-LIVING style lens in the water and bi-pass the cornea by using a PIN HOLE pupil on land eg. seal DIVING ANIMALS Air Type Water Type
