A. only one wavelength that we see as yellow. B. a narrow band of wavelengths that is entirely visible C. mostly long wavelengths that become heat energy. D. a range of many wavelengths from long to very short. Correct response: D Physical Science understanding that the Sun is a source of energy and that energy arrives at Earth’s surface as light with a range of wavelengths Benchmark PS-M-C3: Denise was driving east over a hill in the afternoon, shortly after a rain shower. Suddenly the sun broke through the clouds, and she saw a rainbow ahead of her. Which of the following made the rainbow possible? A. Sunlight can be separated into all the colors of the rainbow. B. Water reflects sunlight like a mirror to make it look colored. C. Overhead black clouds reflect in puddles to cause a mirage. D. Air pollution causes the sky to look colored under these conditions. Correct response: A Life Science Benchmark LS-M-A2: comparing and contrasting the basic structures and functions of different plant and animal cells Which statement about plant and animal cells is true? Both have a cell wall to give them support. A. B. Both have a large vacuole to store water. C. Both use mitochondria to produce energy. Both use chloroplasts to store energy. D.
