Which examples shows how another uses a pattern to transfer information? a a dolphin uses a series of clicks and whistles b a zebra has repeating black and white stripes c a plant has six petals in each flower 17 Why can humans see objects such as a desk or chair? a because these objects refract light b because these objects reflect light c because these objects absorb light
